Giving An Effective Oral Presentation Goals English Language Essay

Giving An Effective Oral Presentation Goals English Language Essay INTRODUCTION An effective oral presentation achieve their objective and usually bring some benefit and learning to all the people involved in them, whether presenter, audience or tutor Chivers, B. Shoolbred, M. (2007) 1.1 What Is Oral Presentation Oral presentation involves communication between a speaker and an audience. Oral presentation is a process of speaking to a group of audience. The aim of presentation is usually to inform, to persuade the audience to act, to influence, to entertain, or to make audience think in a certain way. 1.2 Outline Academic Context Where English Is Important According to Crystal, D. (1997), English language is important because it has been widely dispersed around the world, become the leading language of international discourse, and has acquired use as lingua franca in many regions. English is a dominant language or in some instance even the required international language of communication, science, information technology, business, aviation, entertainment, radio and diplomacy.  [1]   1.3 Need For Speech Training In English Speaker can refine their craft with ongoing training and education. Speaker will be a more effective communicator and will be able to influence and persuade audience as speech training increase speaker confident in spoken skills. Skills training included: Interpretion of symbols to create meaning. Regulative rules and constitutive rules in communication. Punctuation in communication affects meaning. Voice attributes (i.e., volume, pitch, intonation, tone, tempo, enunciation and pronunciation) affect speech quality. A confident speaker is more likely to use this as excitement and create effective speech thus increasing their overall ethos.  [2]   SPEAKING IN A FORMAL ACADEMIC CONTEXT 2.1 Description Of The Transactional Model Of Communication Transactional model shows communication as an ongoing and continuously changing process which takes into consideration the effects of noise, time and systems. In transaction model, communicators can be a speaker and a listener, and can send and receive messages simultaneously. In fact, the word transaction indicates that the communication process is cooperative. In other words, communicators that is senders and receivers are both responsible for the effect and effectiveness of communication. In a transactional encounter, people do not simply send meaning from one to other and then back again; rather, they build share meaning.  [3]   2.2 Public Speaking Skills And Strategies Speaker can improve social skills to conquer fear of speaking in front of an audience. Speaker can boost self-confidence and project better in diverse situations. An effective speaker exerts a dynamic hold on an audience and can be very persuasive. A good speaker is usually sensitive to audience needs and reactions. Public speaking enhance academic and professional abilities. Speaker can be more critical when analysing arguments and information given. Speaker also able to respond appropriately to criticism and arguments. Public speaking skills help speaker to be more adept at reaching out to various types of people as speaker tailor speech to the needs of different audiences. Speaker also enhance leadership skills as speaker learn to present views and convince, and sway audience all without causing offence or slight to any group of people. There are many strategies to delivery presentation: Think positively. Change the way to think. Build confidence through careful preparation. Make use of a positive visualisation process to reduce anxiaty. Go through a positive public speaking experience or enlist the help of someone who can guide. Systemic desensitisation is used to treat many fear. It focuses on reducing the physical symptoms related to anxiety associated with any event and teaches people how to relax. The aim is to associate feeling good and relaxed with communication situations. Skills training in public speaking will teach ways to organise ideas as well as prepare and delivery speeches. Learning more about oral presentation skills will also help feel confident about giving speeches. Prepare and practse speech. Remember the main points, write down notes on cue cards and express what to say naturally.Get family or friends to listen and get feedback. Many relaxation techniques can be used to help to release tension when to give a speech. A simple one is to breathe deeply and then exhale slowly. The best way to minimize fear or anxiety is to get as much public speaking experience. With experience, initial fear will give way to comfort, confidence and even enjoyment. 2.3 Importance And Types Of Audience Analysis Audience analysis is essential in determining how speaker can build their presentation. Speaker would need to know the audience and purpose of the presentation because it affects the equipment to use, the level of preparation need to make, the type of attire need to wear etc. Make enquiries about the audience, with respect to their gender, age, social, economic, and educational backgrounds, prior knowledge, expectation, likes and dislikes, occupational backgrounds, place of residence, habits personality etc. The style of presentation should also be in tune with audience. PREPARING AN ORAL PRESENTATION 3.1 Setting And Audience Speaker familiar with the setting in which the speech is to be made is one way to reduce panic attacks and minimise the risk of unexpected problem cropping up at the last minute. For instance, speaker should find out the exact location of the place where the presentation is to be held. Start off early for the place if it is in the midst of a traffic congestion area. If arrive early, check whether need to go up on stage to present talk, and if there is a rostrum or not. Also check the public address system and the equipment that needs to be utilised. There is always the risk that the computer and the LCD projector might not function properly, find out how can get in touch with technicians who can assist when this happen. Purpose And Topic Purpose of presentation must be linked to the presentation topic. Based on this purpose, speaker must then spell out the objective. According to Cleary, S. (2008), the presentation must have a clearly defined purpose, to ensure a clear focus. The purpose of the presentation influences the choice of objective. The objective should be more specific. Structuring The Presentation Presentation must be structured in such a way so as to reflect clarity and smoothness. Audience is a listening audience and not a reading one. Audience cannot pay attention for a long period of time and may find the presentation difficult to follow if it is not systematically structured and organised. Structuring begin from main ideas. The issues that need to be discussed within each main point should be reduced in scope, especially when there is a likehood that the presentation would go beyond the limit. Each of the main ideas should be properly introduces, arranged and concluded. The sequence of main ideas should in a a manner that makes it easy for the audience to follow, such as start from the easier to the more difficult, or from the known to the unknown. Speaker can also opt to follow a time sequence. The arrangement of the points can also follow a logical sequence. Choosing Appropriate Support Materials Information can be found anywhere. In formal ways as in lectures, tutorials, books, newspapers, speeches, radio, TV etc., or in informal ways as in conversations, gossip, personal notes, memo, hearsay etc. Information can be found in a variety of media, formats and scripts. Not all information is relevant or suitable for speaker presentation. Evaluate the information obtained and select that which important for presentation. The ideal stage for evaluating the materials retrieved should be at the point of reading them, following the criteria setted. The scope, range and depth of presentation will depend on the evaluation and selection criteria that have setted. There are five criteria used in evaluating information; authority, accuracy and reliability, objectivity, currency and scope.  [4]   The material collected can be put into certain categories based on the main ideas raised. There might be a nedd to create sub-ideas under each main idea. Rehearsing The Presentation Speaker should rehearse presentation until confident that speaker can handle all aspect with finesse. Rehearse not only the verbal content of the presentation but also speaker posture, gesture and use of presentation aids.  [5]   Rehearsing can be done in front of a mirror. Speaker can see how their stand, look and deliver presentation. Rehearsing also can be done in front of friends who will give fair and honest feedback about content and delivery. MAKING AN EFFECTIVE ORAL PRESENTATION 4.1 Introducing The Topic An important step when giving an oral presentation is to introduce the topic before beginning to talk about it. This help to prepare the audience to listen to the presentation. 4.2 Presenting The Content When presenting the content, it is important to organise the presentation. It is good to outline what is speaker going to speak about. Make sure that the outline consists of introduction, body of content and conclusion. When making a presentation, make sure to stand straight and maintain eye contact with the audience. Dont forget to greet the audience before start presentation. Try not to read from notes. Talk to audience instead. Speak with an even tone. Be loud enough to be heard but do not shout. Drawing A Conclusion An important step when giving an oral presentation is to conclude the talk well. Speaker should summarise the main points of the presentation. This helps the audience to grasp what has been said. When its over, thank the audience for being good listener and leave with a smile. 4.4 Tips For Effective Delivery Here some proven tips on how to build confident and give better presentation: Know more about material than what been include in presentation. Use humour or personal storiese. So, that way speaker would not easily forget what to say.  [6]   Practise, practise and practise! Rehearse out loud with all equipment to use. Revise as necessary. Work to control filler word; practise, pause, breathe. Practise with a timer and allow time for unexpected.  [7]   Know the room. Arrive early, walk around the speaking area and practise using the microphone and any visual aids.  [8]   Know the audience. Greet the audiences. Its easier to speak to a group of friends than to strangers.  [9]   Relax. Transform nervous into enthusiasm. Concentrate on the presentation. Focus attention away from anxiety. SUMMARY

CIRCUIT SWITCHING AND PACKET SWITCHING 1) INTRODUCTION Telecommunication networks carry information signals among entities, which are geographically for apart. The communication switching system enables universal connectivity. Switches can be valuable asset to networking[1]. Overall, they can increase the capacity and speed of our network. Every time in computer network we access the internet or another   computer network outside our immediate location, our messages are sent through a maze of transmission media and connection devices.The mechanism for moving information between different computer network and network segment is called switching in computer network[2]. Figure 1: Switched network Long distance transmission is typically done over a network of switched nodes. Nodes not concerned with content of data. A collection of nodes and connections is a communications network. Data routed by being switched from node to node. Nodes may connect to other nodes only, or to stations an d other nodes. Node to node links usually multiplexed. However, switching should not be seen as a cure-all for network issues.There are two different switching technologies which are: 1) Circuit switching and 2) Packet switching. 1. Circuit Switching Circuit switching was the first switching technique have been used in communication network. This is due to easy to carry analog signals. Circuit switching  network establishes a fixed bandwidth channel between nodes before the users may communicate, as if the nodes were physically connected with an electrical circuit. The bit delay is constant during the connection, as opposed to packet switching, where packet queues may cause varying delay.In circuit switching, the transmission medium is typically divided into channels using Frequency Division Multiplexing (FDM), Time Division Multiplexing (TDM), or Code Division Multiplexing (CDM). A circuit is a string of concatenated channels from the source to the destination that carries an inf ormation flow. To establish the circuits, a signaling mechanism is used. This signaling only carriers control information, and it is considered an overhead. Since all decisions are taken by the signaling process, the signaling mechanism is the most complex part in circuit switching.Each circuit cannot be used by other callers until the circuit is released and a new connection is set up. Even if no communication is taking place in a dedicated circuit then, that channel still remains unavailable to other users. Channels that are available for new calls to be set up are said to be idle. Telephone network is example of circuit switching system. Virtual circuit switching is a packet switching technology that may emulate circuit switching, in the sense that the connection is established before any packets are transferred, and that packets are delivered in order.Unlike with packet switched networks, we cannot just send a ‘packet’ to the destination. We need to establish and la ter terminate the connection. We need to have some way of transmitting control information, we can either do this in band that the same channel we use for data or out of band which is on a seperate dedicated channel. Phone networks used in band signaling a while ago we could control switching and other functionality by playing tones into the telephone. Today in band signaling is considered unsecure and is not used except for compability with old systems[3]. 2. Packet SwitchingPacket switching  is a communications paradigm in which packets are routed between nodes over data links shared with other traffic. In packet-based networks, the message gets broken into small data packets. These packets are sent out from the computer and they travel around the network seeking out the most efficient route to travel as circuit become available. This does not necessarily mean that they seek out the shortest route. Each packet may go different route from the others. Each packet contains a  "header† with information necessary for routing the packet from source to destination.The header address also describes the sequences for reassembly at the destination computer so that the packets are put back into the correct order. Each packet in a data stream is independent. To be able to understand packet-switching, we need to know what a  packet  is. The  Internet Protocol (IP), just like many other  protocols, breaks data into chunks and wraps the chunks into structures called packets. Each packet contains, along with the data load, information about the IP address of the source and the destination nodes, sequence numbers and some other control information.A packet can also be called a segment or datagram. Once they reach their destination, the packets are reassembled to make up the original data again. It is therefore obvious that, to transmit data in packets, it has to be digital data. The packet switching can broadly be divided into two main categories, first is the virtual circuit approach and other is the datagram approach. In the virtual circuit approach to packet switching, the relationship between all packets belonging to the message or a session is preserved. A single route is chosen between the sender and the receiver at beginning of the session.When the data are sent, all packets of transmission travel one after another along that route. The wide area networks use the virtual circuit approach to the packet switching. The virtual circuit approach needs a call setup for establishing a virtual circuit between the source and destination. A call teardown deletes virtual circuit. After the setup, routing takes place based on the identifier known as the virtual circuit identifier. This approach can be used in the WANs, frame relay and an ATM. In the other approach of packet switching that is the datagram approach, each packet is treated independently of all others.Even if one packet is just a piece of a multi-packet transmission, the ne twork treats it as though it is existed alone. Packets in this approach are known as the datagram. The internet has chosen datagram approach to switching in the network layer. It uses the universal addresses defined in network layer to route packets from the source to destination. In  packet-switching, the packets are sent towards the destination irrespective of each other. Each packet has to find its own route to the destination. There is no predetermined path; the decision as to which node to hop to in the next step is taken only when a node is reached.Each packet finds its way using the information it carries, such as the source and destination IP addresses[4]. 2) HISTORY OF CIRCUIT SWITCHING AND PACKET SWITCHING * Evolution of Circuit Switching Switches are used to build transmission path between telephone set on a flexible basis. Without switches, each telephone set would require a direct, dedicated circuit to every other telephone set in order to be able to communicate. This is a full-mesh physical topology network. Such a full mesh network clearly is resource-intensive, impractical and even impossible, as early experience proved.Circuit Switching were developed for voice communications. Contemporary circuit switches provide continuous access to logical channels over high-capacity physical circuits for the duration of the conversation. In January 1878, the first telephone switch went into operation in New Haven Connecticut. Switching technology had advanced drastically over the intervening decades, yet the basic function had remained the same: interconnect users of telephones by creating circuits between them. Every telephone has a line, or circuit, that connects physically to a telephone switch.In the simple case of both the person making the call and the person being called are connected to the same switch, the caller dials the number of the desired person, the switch checks to see if the line is available, and if it is, the two lines are interconnec ted by the switch. The connection is maintained until one person hangs up his or her telephone, at which time the switch terminates the connection, freeing both lines for other calls. Three characteristics of this type of switching, called â€Å"circuit switching,† are important.First, before the two parties can talk the circuit between them has to be created, and it takes time for a switch to check if a connection can be made and then to make the connection. Second, when a connection has been made, it creates a dedicated connection. No other party can reach either party of a dedicated connection until that connection has ended. Three, since switches are very expensive one accounting policy telephone companies implemented to recover their investment was to institute a minimum charge for every telephone call, generally three minutes.For voice calls that lasted many minutes, a minimum charge did not represent a problem. But communications between computers often last less than seconds, much less minutes. It was difficult to image how circuit switching could work efficiently for computer communications when such a system took minutes to make a connection, created dedicated connections so only one person, or party, could be in connection with another party, and had a prohibitive cost structure. Although these issues were generally understood before the experiments of Roberts and Marill in 1965, they were once again strongly confirmed.The experiments also made it abundantly clear that the problems confronting computer communications were not only with the circuit-switching architecture of the telephone system. Host operating system software of the day assumed there was only one Host and all connecting devices were as if â€Å"slaves. † Hosts were not designed to recognize or interact with peer-level computers; the concept of peer-level computing did not yet exist. Thus, in interconnecting two computers, one had to be master and one slave. The problem only became worse if more than two computers wanted to interconnect and communicate.Nevertheless, the problem of Host software was considered to be solvable if a suitable communication system could be designed and made to work. Fortunately, an inquisitive innovative scientist, Paul Baran, had already explored the problems of circuit switching beginning in 1959. By 1962, he had made his concept of a message-based communication system publicly known. Independently, in 1965, an English scientist, Donald Davies reached the same conclusions as had Baran and would coin its name: packet switching. * Evolution of Packet Switching The concept of packet switching had two independent beginnings, with Paul Baran and Donald Davies.Leonard Kleinrock conducted early research and authored a book in 1961 in the related field of digital message switching without explicitly using the concept of packets and also later played a leading role in building and management of the world’s first packet s witched network, namely the ARPANET. Baran developed the concept of packet switching during his research for the US Air Force into survivable communications networks, first published in 1962, and then including and expanding somewhat within a series of eleven papers titled â€Å"On distributed communications† in 1964.Baran’s earlier paper described a general architecture for a large-scale, distributed survivable communication network. His paper focused on three key ideas: 1) the use of a decentralized network with multiple paths between any two points, 2) dividing complete user messages into what he called message blocks (packets), and 3) delivery of this message by store and forward switching. Baran’s study paved the way for Robert Taylor and J. C. R.Licklider, both wide-area network evangelists working at the Information Processing Technology Office, and it also helped influence Lawrence Roberts to adopt the technology when Taylor put him in charge of developm ent of the ARPANET. Baran’s packet switching work similar to the research performed independently by Donald Davies at the National Physical Laboratory, UK. In 1965, Davies developed the concept of packet switched networks and proposed development of a U. K. wide network. He gave a talk on the proposal in 1966, after which a person from Ministry of Defense told him about Baran’s work.At the 1967 ACM Symposium on operating system principles, Davies and Robert bringing the two groups together. Interestingly, Davies had be chosen some of the same parameters for his original network design as Baran, such as a packet size of 1024 bits. Roberts and the ARPANET team took the name â€Å"packet switching† itself from Davies work. In 1970, Davies helped build a packet switched network called Mark I to serve the NPL in the UK. It was replaced with the Mark II in 1973, and remained in operation until 1986, influencing other packet communications research in UK and Europe[5]. 3) COMPARISON BETWEEN CIRCUIT AND PACKET SWITCHINGCircuit Switching: In circuit switching a message path or data communication path or channel or circuit is dedicated to an entire message block during the process of message transmission. The entire bandwidth is dedicated to the said message as it were, and before any data transmission can take place circuit initialisation and setup has to be done to enable or determine the avalaibility of the link as in trying to make a call using the telephon line for voice messaging or even dial-up procedure where you need to establsih that the line is free for use in the first place; and then have the line engaged all through your time of use.All the message travel through the same path and keep the link engaged all the while when the block of message is been relayed or transmitted. In circuit switching, whole of the data travels along a single dedicated path between the two terminals whereas in datagram switching data is divided into packets an d each of these packets are treated indepently and travel along different paths, source and destination being the same. Circuit switching concept is used in Telephony networks where a dedicated line is assigned to particular connection, the connection in this case is permanent during the connection.Considerable amount of bandwidth is wasted in this process and at a time only one way communication is possible. Circuit switching is done at physical layer whereas datagram switching is generally done at network layer. Circuit switching requires the resources to be reserved before the transmission of data but datagram switching doesn’t require such reservation of resources. Advantages: 1. Fixed delays, because of the dedicated circuit – no interference and no sharing. 2. Guaranteed continous service, also because of the dedicated circuit. . Guaranted the full bandwidth for the duration of the call. Disadvantages: 1. Takes a relatively long time to set up the circuit. 2. Dif ficult to support variable data rates and is not efficient for burst traffic. The equipment may be unused for a lot of call, if no data is being sent the dedicated line still remains open. 3. During crisis or disaster, the network may become unstable or unavailable. 4. It was primarily developed for voice traffic rather than data traffic. Packet Switching:In packet switching the block of data is split into small units with each unit having a sequence number attached to it for orderly identification within a given message block and these different units are usaully sent across the available diffrent links or channels of data transmission from one end to the other end point where they arrvive at different times but have to be assembled together in the correct order at this location via the sequence numbers to get out the original message back without any data degredation occuring as a result of the different paths of transmissions from source to destination.Also no single data channel is dedicated to any given message block in the course of transmission as many units of different messages can be multiplexed and then get demultiplexed at their deffferent destinations correctly since there are codes to differentiate each unit of message, resulting to no conflict at all. Packet switching splits messages into small units and transmitting them to destination using different paths while at the same time keeping tracks or maintaining an orderliness of the units for proper and correct reassembling of the units to get the original message back.Packet switching is generally used in Internet data transmmission where we send data without minding if the link is free or not as far as we are connected and the pieces of information that we sent are then split into smaller units and then sent in packets, with each packets switched through different data channel most times and with no loss at the end. The main advantage of packet-switching is that it permits â€Å"statistical mu ltiplexing† on the communications lines. The packets from many different sources can share a line, allowing for very efficient use of the fixed capacity.With current technology, packets are generally accepted onto the network on a first-come, first-served basis. If the network becomes overloaded, packets are delayed or discarded (â€Å"dropped†)[6]. Advantages: 1. Since packet are typically short, the communication links between the nodes are only allocated to transferring a single message for a short period of time while transmitting each packet. Longer messages require a series of packets to be sent but do not require the link to be dedicated between the transmission of each packet.The implication is that packets belonging to other messages may be sent between the packets of the message being sent from one node to other node. This provides a much fairer sharing of the resources of each of the links. 2. The ability to do statistical multiplexing which can exploit the i nherent â€Å"burstiness† in many data applications and thereby enable sharing of the network resources more efficiently among multiple data streams is a major advantage. 3. Pipelining†- This simultaneous use of communications links represents a gain in effieciency, the total delay for transmission across a packet network may be considerebly less than for message switching, despite the inclusion of a header in each packet rather than in each message. Disadvantages: 1. Packets arriving in wrong order. 2. Under heavy use there can be delay. 3. Protocols are needed for a reliable transfer. 4. Not so good for some types data streams. Real-time video streams can lose frames due to the way packets arrive out of sequence[7]. ) PERFORMANCE ANALYSIS Circuit Switching In circuit switching, a unique connection is used to move data between the two end user[8]. â€Å"Circuit-Switched type networks† are most commonly portions of the ubiquitous telephone networks to which we ar e all accustomed. In these networks, which generally transmit voice or data, a pribate transmission path is established between any pair or group of users attempting to communicate and is held as long as transmission is required.Telephone networks are typically circuit switched, because voice traffic requires the consistent timing of a single, dedicated physical path to keep a constant delay on the circuit. Figure 2: Example of circuit switching Figure 3: Public circuit switching network Subcribers: The device that attach to the network. Subscriber loop: The link between the subscriber and the network. Exchanges: The switching centers in the network. End office: The switching center that directly supports subscribers. Trunks: The branches between exchanges. They carry multiple voice-frequency circuit using either FDM or synchronous TDM.Figure 4: Circuit establishment Basic performance equation for a single link in a circuit-switched network: Let’s consider a system with N cir cuits on a single link, with customers arriving according to a Poisson process at rate ? customers per second, and with successful customers having a mean holding time of h seconds, distributed as a negative exponential distribution with parameter ? = 1/h. If a customer attempting a new call finds all the circuits busy, there are no waiting places, so we’ll assume that the customer just goes away and forgets about making the call.Define the state of our system by the random variable K, where K represents the number of customers currently in the system, then K can take on any integer value in the range from 0 to N. With these assumptions, our model is simply a state-dependent queue, with arrival rate (independent of the state), and service rate i when the system is in state K=i. This is known as an M/M/N/N queue: Markovian arrivals, Markovian service time, N servers, and a maximum of N customers in the system. We can draw the following Markov chain diagram to represent the sy stem.When there are I customers the service rate is i , which is due to the fact that there are i customers, each with a service rate ? , so the total service rate is i. Figure 5: Markov chain diagram Under conditions of statistical equilibrium, the solution is: pi=AiN! j=0NAjj! Observe that this is simply a truncated Poisson distribution and also the result depends on the traffic A, and not the specific values of ? and ?. To establish a path in circuit switching three consecutive phases are required: 1. Connection establishment. 2. Data transfer. 3.Connection teardown. Elements of a circuit-switch node (Figure 6): * Digital Switch: Provides a trasnparent signal path between any pair of attached devices. * Control Unit: Establishes, maintains and tears down connections. * Network Interface: Functions and hardware needed to connect digital and analog terminals and trunk lines. Figure 6: Circuit switch element Packet Switching In packet switching, data are broken into packets of fixed or variable size, depending on the protocol used. The performance of packet switching is called best effort performance.If you transmit from sender to receiver, all the network will do its best to get the packet to the other end as fast as possible, but there are no guarantees on how fast that packet will arrive. Figure 7: Example of packet switching Packet switching is used to optimize the use of the channel capacity available in digital telecommunication networks such as computer networks, to minimize the transmission latency, the time it takes for data to pass across the network. It is also used to increase robustness of communication. These layers are introduced to break down the complexity of communications.The top layer (layer 7) is the layer at user level. As the layers go down, they get increasingly primitive. Layer is most primitive from as it is just binary numbers prepared to be transmit to the end node. Seven layers of open systems interconnection models are shown in ta ble 1[7]: Layer Number| Name| Description| 1| Pysical Layer| Deals with physical connection between nodes in network. | 2| Data Link Layer| Maintaining and optimising actual connection. | 3| Network Layer| Deals with communication of data on a network. | 4| Transportation Layer| Sequencing, error detection and optimisation of communication. 5| Session Layer| Controls the communication between applications running on end nodes. | 6| Presentation Layer| Format data and provides syntaxes for application. | 7| Application Layer| Contains management functions. | Table 1: Layers of open systems interconnection model Every packet contain some control information in its header, which is required for routing and other purposes. Figure 8: Packet data format Initially, transmission time decreases as packet size is reduced. But, as packet size is reduced and the payload part of a packet becomes comparable to the control part, transmission time increases.Figure 9: Variation of transmission time with packet size. As packet size is decreased, the transmission time reduces until it is comparable to the size of control information. There is a close relationship between packet size and transmission time as shown in Figure 9. In this case it is assumed that there is a virtual circuit from station X to Y through nodes a and b. Times required for transmission decreases as each message is divided into 2 and 5 packets. However, the transmission time increases if each message is divided into 10 packets[9].The packet switched networks allow any host to send data to any other host without reserving the circuit. Multiple paths between a pair of sender and receiver may exist in a packet switched network. One path is selected between source and destination. Whenever the sender has data to send, it converts them into packets and forwards them to next computer or router. The router stores this packet till the output line is free. Then, this packet is transferred to next computer or router ( called as hop). This way, it moves to the destination hop by hop. All the packets belonging to a transmission may or may not take the same route.The route of a packet is decided by network layer protocols. As we know there are two approaches for packet switching which are: 1. Datagram switching, 2. Virtual circuit swtiching. 1. Datagram Switching: Each packet is routed independently through network which is also called connectionless packet-switching. Datagram packet switching sends each packet along the path that is optimal at the time the packet is sent. When a packet traverses the network each intermediate station will need to determine the next hop. Routers in the internet are packet switches that operate in datagraam mode.Each packet may travel by a different path. Each different path will have a different total transmission delay (the number of hops in the path may be different, and the delay across each hop may change for different routes). Therefore, it is possible for the p ackets to arrive at the destination in a different order from the order in which they were sent[10]. Figure 10: Datagram packet switching Figure 11: Delay in datagram packet switching There are three primary types of datagram packet switches: * Store and forward: Buffers data until the entire packet is received and checked for errors.This prevents corrupted packets from propagating throughout the network but increases switching delay. * Fragment free: Filters out most error packets but doesn't necessarily prevent the propagation of errors throughout the network. It offers faster switching speeds and lower delay than store-and-forward mode. * Cut through: Does not filter errors; it switches packets at the highest throughput, offering the least forwarding delay. 2. Virtual Circuit Switching: Virtual circuit packet switching (VC-switching) is a packet switching technique which merges datagram packet switching and circuit switching to extract both of their advantages.VC switching is a v ariation of datagram packet switching where packets flow on so-called logical circuits for which no physical resources like frequencies or time slots are allocated shown in Figure 12. Each packet carries a circuit identifier, which is local to a link and updated by each switch on the path of the packet from its source to its destination[10]. A virtual circuit is defined by the sequence of the mappings between a link taken by packets and the circuit identifier packets carry on this link. In VC-switching, routing is performed at circuit establishment time to keep packet forwarding fast.Other advantages of VC-switching include the traffic engineering capability of circuit switching, and the resources usage efficiency of datagram packet switching. Nevertheless, a main issue of VC-Switched networks is the behavior on a topology change. As opposed to Datagram Packet Switched networks which automatically recompute routing tables on a topology change like a link failure, in VC-switching all virtual circuits that pass through a failed link are interrupted. Hence, rerouting in VC-switching relies on traffic engineering techniques[6].Figure 12: Virtual circuit packet switching Figure 13: Delay on packets in virtual-packet switching 5) APPLICATION OF CIRCUIT AND PACKET SWITCHING Circuit Switching 1. Plain Old Telephone Service (POTS) The plain old telephone system (POTS) is the largest circuit switched network. The original  GSM  network is also circuit switched. Prior to the existence of new types of networks, all communication systems had to be built based on the existing telecommunications facilities, which were largely oriented to what the common carriers refer to as plain old telephone service, known as POTS.Consequently, even today, in order to use POTS for data communications, it is necessary to use a modem to convert the data to a form suitable for voice-transmission media. The data transmission rate that can be obtained over a POTS connection is typically les s than 64 Kbps. These rates are adequate for text and audio transmission. However, they are not suf? cient for good quality video transmission in real-time. 2. Switched 56 Service Switched 56 service is a dial-up digital service provided by local and long distance telephone companies. For a connection, a data service unit/data channel unit (DSU/CSU) is used instead of a modem.Switched 56 service uses a 64 Kbps channel, but one bit per byte is used for band signaling, leaving 56 Kbps for data. This service allows the transmission of information over one or two twisted cable pairs to multiple points at a data rate of 56 Kpbs. 3. Integrated Services Digital Network (ISDN) The ISDN was designed in the 1980s to offer end-to-end digital connectivity, while providing the required QoS with data rates in the range of Kbps to Mbps over switched connections. In order to provide even higher data rates, the original ISDN was extended to broadband ISDN (BISDN) (Martin, 1985).The ISDN services are provided to users as ISDN interfaces, each comprising a number of ISDN channels. Using 64-Kbps channels, called bearer or B channels, ISDN provides access to the digital network. ISDN provides lower error rate compared to typical voiceband modems and a relatively high bandwidth data channel[11]. Packet Switching 1. VOIP It is becoming increasingly accepted to transmit delay sensitive data through a packet switched network (rather than circuit switched). There are protocols that can create a virtually real-time environment – which, for voice conversations, is sufficient.Voice over IP is essentially a voice signal encoded into a digital format, being sent through a packet switched network (or possibly any other network) using the Internet Protocol (IP). Over recent years there have been standards developed and supported by major companies including ITU-T H. 323. VOIP has a long way to evolve before it is used as widespread as circuit switched networks, but it is well on its wa y. 2. IPv6 The current protocol that is employed almost everywhere IP (IPv4) has come to the end of its useful life. This is mainly because it has run out of addresses to uniquely identify every non-private computer in the world.IPv6 has been deigned to be more efficient than IPv4 and solve the addressing problems that we face at present. Ipv6 will use 128 bits to address nodes, which provides 2128possibilities (roughly3. 4? 1038). It will incorporate a special ‘option mechanism’ to store optional headers in the transport layer (to maximize efficiency by reducing required space). Finally, Ipv6 will have support for resource allocation, allowing packets to be part of a ‘traffic flow’ which will provide better communication of data such as video/voice streams [VOIP]. 6) CONCLUSION In large networks there might be multiple paths  linking sender and receiver.Information may be switched as it travels through various communication channels. Data networks can be classified as using circuit-switching or packet-switching. Packet switching, which forms the basis of the Internet, is a form of statistical multiplexing in which senders divide messages into small packets. The switching centers receive the control signals, messages or conversations and forwards to the required destination, after necessary modification link amplification if necessary. In computer communication, the switching technique used is known as packet switching or message switch (store and forward switching).In telephone network the switching method used is called circuit switching. Circuit switching  is a technique that directly connects the sender and the receiver in an  unbroken path. In the modern and fast paced world, what we are looking for is efficiency, low costs and reliability and packet-switched networks seems to fulfill most of the criteria that the society is looking for. It would only be a matter of time before circuit switching becomes a thing of the past. 7) REFERENCES [1] Stallings, W. , Data and Computer Communications, 7th ed. 1999, Upper Saddle River, NJ: Prentice Hall.

The CSR high quality Awards place achievement transversally all industries, non merely nutrient and drink, and are honoured by a committee includes of converting stakeholders, such as nongovernment associations and disposal representatives. The grasp of quality in 3 kind ‘s exhibits the compulsion of the coca-cola Company has for transporting the promises of subsist confidently phase to life at occupation and in the society. Continuous Achievement Award Human Resources Award Environment AwardVision 2020:The world is changing all around us. To protract to win as a concern for the following 10 old ages and beyond, we need to be required to gaze frontward, place with the inclination and services that will calculate out the concern in the chance and advancement rapidly to form for what ‘s to come. We have to acquire prepared for tomorrow today. That ‘s what the 2020 Vision is all sing. It produces a permanent purpose for the production and supplies coca-cola with a â€Å" Route map † for capturing reciprocally with the bottling spouses.Coca-cola MissionCoca-colas Roadmap commences by agencies of the mission, which is lasting. It proclaims the ground as a corporation and provides as the standard oppose which the company see the public presentation and declarations. To stimulate the universe†¦ To promote minutes of assurance and pleasance†¦ To bring forth appraisal and compose a diverseness.Coca-cola visionThe Company ‘s vision is to supply the construction for the Roadmap and conducts each and every characteristic of the trade by explicating what the company necessitate to carry through in order to protract achieving sustainable, high quality development. â€Å" Peoples: Be an tremendous circumstance to make occupation where individuals are enthused to be the best they can be.

Spouses: cultivate a charming system of consumers and providers ; jointly they produce common, permanent value. Planet: Be a painstaking national that makes a differentiation by functioning concept and maintain sustainable communities. Net income: exploit long-standing reaching to stockholders while being attentive of its all duties. Productiveness: Be an extremely efficient, thin and fast-moving organisation. †Undertaking 2Management of Financial RiskHarmonizing to one-year study, it ‘s clearly apparent that, certain financial hazards faced by Coca-Cola Hellenic occur from unfavorable fluctuations foreign Exchange rates, in involvement rates, merchandise monetary values and other market hazards. Company Board of Directors has accepted the Treasury Policy and graph of Authority, which reciprocally afford the organized model designed for every exchequer and exchequer associated minutess.Currency HazardGiven the Group ‘s operation public presentation, they are showing to a major measure of foreign currency hazard. Coca-colas foreign currency revelation comes up from disagreeable transforms in trade rates with the euro, the US dollar and the exchanges within its non-euro Kingdoms. Operation constitutions begin largely from the stuffs acquired in exchanges such as the US dollar or euro which can ste er to maximal cost of trade in the functional currency of the state. Conversion constitutions occur as several of its processing includes efficient currencies other than euro, and any alteration in the functional currency against the euro impacts our amalgamate income statement and balance sheet when consequences are converted into euro. Coca-cola exchequer program involves the lie of come oning Twelve month estimated operational results contained by the distinguishable least ( 25 % ) and maximal ( 80 % ) exposure phases. Beat around the bushing off from a Twelve month span may originate, subject to convert greatest coverage degrees, granted the estimated minutess are highly believable. Where available, we use derivative fiscal instruments to cut down our cyberspace revelation to currency changeableness. These conventions by and large established in one twelvemonth.Interest HazardThe Team represents to market hazard happening from changing involvement rates, foremost and first in the euro zone. Intermittently they estimate the needed combination of fixed and drifting rate duty and accommodate the involvement disbursals based on the needed combination of debt. They cope up the involvement rate outgo by agencies of an agreement of lasting and drifting rate debt, involvement rate switch and pick cap understandings. Thou gh they have denial topographic point of mark for the mixture of set to drifting rate liabilities, traditionally they have been excess demoing to drifting rates as this has be inclined to move as a expected evade against on the whole concern hazard.Recognition HazardRecognition hazard is inhibited by a probationary process as to the option of likely oppose parties for exchequer traffics. The Company ‘s recognition hazard is handled by establishing a permitted opposition party and state confines, detailing the highest experience that they organized to acknowledge with respect to single counterparties or states. The limitations are reconsidered and observed on an expected footing.Liquid HazardThe common scheme is to keep a least measure of liquidness engages in the construction of currency on the balance sheet when prolonging the stableness of our liquidness engages in the assortment of idle dedicated comfortss, to do certain that the Company incorporate cost-efficient admit to enough economic assets to convene the fiscal support desires. These embrace the everyday backup of all its procedure in add-on as the support of the resource expense plan. In order to relieve the chance of liquidness restrictions, Company make an attempt to prolong a least of a‚ ¬250 million of financial headway. Monetary headway refers to the excess engaged support gettable, subsequently than sing hard currency flows from working public presentation, dividends, acquisitions, revenue enhancement disbursal, involvement disbursal and capital outgo demands. Hazard Map:10High 9 Quadrant II ( Detect & A ; proctor ) Quadrant I ( Prevent at Sources )8Significance 76Low 5 Quadrant IV ( Low Control ) Quadrant III ( Monitor )43211 2 3 4 5Low Likelihood HighThe hazard map places every hazard in the following four Quadrants:Prevent at beginning hazardHazards in this Quadrant are categorized as premier Hazards and are rated High precedency. They are important hazards that intimidate the achievement of concern intents. These hazards are reciprocally considerable in significance and likely to originate. They should be condensed or removed with defensive reins and must be organize appraisal and testing.Detect and Monitor RisksHazards in the quarter-circle are momentous, but they are fewer possible to originate. To do certain that the hazards stay small chance and are administered by the concern appropriately, they require detecting on a revolving base. Detective powers must be positioned into a topographic point to do certain that these high effect hazards will be identified in front of they harvest up. These hazards are 2nd chief concern behind premier hazards.Monitor RisksHazards in the quarter-circle are non really of import, but contain a superior possibility of go oning. These hazards should be watched decently to attest that they are being decently supervised and that their deduction has non distorted due to changing concern fortunes.Low Control RisksHazards in this quarter-circle are every bit unlikely to take topographic point and non considerable. They involve least observant and oversee if non attendant hazard class.Undertaking 3a )Hazard FactorsIn Further the consequent issues, which may extensively act upon the trade, fiscal circumstance or consequences of operations in future periods? The hazards explained below are non the individual hazards confronting Coca-Cola Company. Further risks non presently recognized by company or that they soon consider being inappropriate besides may efficaciously unfavorably impact the concern, economic status or consequence of operations in future periods.Current hazard faced by Coca-colaHealth Concerned RiskCustomers, communal physical status functionaries and authorities functionaries are suitably increasing concerned about the public fittingness effects connected with stalwartness, chiefly between adolescent public. And besides, few research workers, fittingness protagonists and nutritionary proces ss are heartening clients to diminish outgo of sugar-sweetened drinks, together with those sugared with HFCS or other alimentary sweetenings. Rising community anxiousness refering these affairs ; likely new dues and law-making system concerns the advertisement, labelling or handiness of the drinks ; and harmful publicity consequential from definite or endangered authorised public presentation in resistance to the coca-cola or other companies in its industry relating to the advertisement, labelling or trade of sugar-sweetened drinks might diminish demand for company ‘s drinks, which may perchance act upon its profitableness.Environmental HazardH2o ( H2O ) is the major component in significantly all of the coca-cola merchandises. It is besides a partial beginning in several parts of the universe, confronting supreme differences from over use, mounting taint, broken disposal and conditions alteration. As demand for H2O prolongs to heighten all-around the universe, and as H2O beco mes scarcer and the high quality of gettable H2O deteriorates, Company ‘s categorization might obtain increasing production costs or face possible boundaries which could destructively alter the productiveness or net purposeful returns in the drawn-out tally.Business & A ; fiscal hazardThe non-alcoholic drinks concern milieus is hurriedly developing as a consequence of, among other things, alterations in clients dispositions, together with altered based on wellness and nutrition concerned and obesity anxiousnesss ; variable consumer gustatory sensations and needs ; alterations in clients criterion of life ; and spirited merchandise and pricing demands. As good, their fabrication is being affected by the tendency toward consolidation in the market conduit, particularly in Europe and the United States. If they are unable to successfully accommodate to this quickly altering environment, the company ‘s portion of gross revenues, capacity growing and overall economic classs co uld be depressingly affected.Hazard factors which the Company may confront in futureTechnological HazardCoca-cola relies on informations based cognition system and strategies, include the Internet, to patterned advance, broadcast and store electronic information. Particularly, Coca-cola depends on its information engineering communications for digital advertisement public presentation and electronic substructure in its countries about the universe and between Company forces and our bottlers and other clients and providers. Defence misdemeanor of this substructure can make system breaks, closures or unauthorised revelation of classified information. If they are non capable to forestall such breaches, Company ‘s operations could be disrupting, or they might undergo economical harm or loss because of doomed or misappropriated information.Climate hazardThe gross revenues of the merchandises are inclined to several extents by clime fortunes in the markets in which they function. Qu eerly wintry or rainy weather conditions at some point in the summer months could hold a probationary effect on the insist for all its merchandises and contribute to lower gross revenues, which could hold an inauspicious consequence on our consequences of operations for such periods )Risk analysis & A ; direction techniquesRisk direction often concentrates on affairs of insurance. Conversely, there are figure of farther chief considerations when measuring countries of hazard into a large concern†¦ ab initio ; they require every bit dependability and the infrastructural proficiency to do the patterned advance. Second, they should wholly acknowledge their association, and its patterned advances and aims. And thirdly, they must be dwelling of support and keep up from the association and the administrative squad. Coca-cola Amatol ( CCA ) comes under the class of being hazard witting, but non obsessed by dictatorial status. CCA is increasing its hazard direction representation to pull off enterprise-wide and supply to the eventual productiveness of the concern. This consequence will be achieved non merely by prolonging sound concern determinations but besides all the manner through constellation of the organisation ‘s schemes with its stockholders ‘ and investors ‘ aspiration to do certain that efficient concern authorization is in topographic point. CCA, inside the broader coca-cola construction, is on an ERM expedition. They are determined to take out the conventional split and ‘soloed ‘ attack that regularly exists in organisations and they are duty so by taking an blessing and ownership of the hazard direction procedure. At CCA they know the significance of the indispensable values of the ERM procedure. They are: a dedication to the journey ; an sensible model that embraces a general linguistic communication ; a unvarying attack to- no affair the nature of the concern unit or its aims ; a statement signifier that identifies stakeholders, corresponds the class and aims ; and drives literary alteration ; and guaranting advice of the result through an riddance of ‘black holes ‘ or ‘silos ‘ .Risk Management PlanThere are four phases to put on the line direction planning. They are: A · Hazard acknowledgment Hazards Quantification Hazard reaction Hazard Monitoring and ControlTypesThere are several definite hazard direction techniques as there are kind of industry, but one time a hazard has been recognized and considered, mostly attempts at warranting the hazard autumn into four indispensable grouping in malice of the model. The initial, bar, can be every bit easy as non perpetrating in activity that manufactures the hazard, but this non merely eradicates hazard but possible benefits every bit good. Hazard decrease through concrete stairss is far more general, and the specifics will be associated to the type of concern and hazard involved. Hazard transference is besides extremely advantageous as when an accessible pick ; it involves outsourcing the trouble to an extra article such as in the class of get of insurance. Ultimately, hazard saving is predictable in a few instances where the hazards are either unlikely, or the costs of explanatory or reassigning the hazard are inordinate. C ) Communicating with interest holders Many of coca-cola stakeholders consist of all those who are by and large influenced by or who most influenced the means the company run the large concern. This includes clients, consumers, contractors, and workers, Government & A ; supervisors, NGOs plus the confined communities in which the company operates. Coca-cola regularly connect with its major stakeholders as exposed in Diagram In add-on, they conceded a elaborate probe in March 2007 to sort the most of import countries of concern for its stakeholders. This implicated a sequence of focal point groups with clients aged 18 and over and with work force of both CCE and CCGB. It besides incorporated the interviews with consumers, non-governmental administrations and the media. The survey exposed a strong understanding of appraisal between the diverse stakeholder groups and provided an obvious graph of the countries of liability they most require to concentrate on all these countries. Coca-cola stakeholder survey has besides helped out to polish its chance scheme on communal and ecological issues. On every key subject it contains ‘Next Step ‘ – the act which has to be taken in the undermentioned twelvemonth to attest that the concern persists to do an optimistic impact.Consumer CommunicationOn June 11 2010 Coca-cola has published that the Coca-cola Poland has completed a first move a caput frontward in how it instructs clients sing recycling, by incorporating its ‘Recover-Recycle ‘ activity into every chief coca-cola labelled or supported immense events this twelvemonth. A huge My Coke trying plan, which happened between April and September 2010, is one of the cardinal promoting public presentations where coca-cola Poland will describe to clients about the net income of recycling through Recover-Recycle.Decision:There is no uncertainty that the Coca Cola is the 2nd largest drinks company in the universe. However, it should work on above mentioned lacks to get the better of them and strive to do its rivals lagged behind. The Company coca-cola have a corporate ( Head Office ) subdivision that is apt for giving the Company a mostly class and provided that sustain to the provincial formation. Means considered pick at the Coca-Cola Corporation are completed by a managerial Committee of 12 concerned Officers. This committee assisted to organize the six strategic precedences set out in old. The fiscal resources allotment for the Vision 2020 had been discussed under the six P ‘s as laid out by the company. International through to grass-roots and the c ommunity, Coca-Cola has strengthened its place as a football insider and this helps to construct the trade name and corporate repute of Coca-Cola. Last twelvemonth, Coca-cola saw its gross revenues decreased in UK market. In order to re make the gross revenues, Coca-cola to specify new communicating program such as ‘Recover-Recycle ‘ activity.

Erik Erickson Child Of An Extramarital Affair - 2795 Words

Erik Erickson was born on June 15, 1902 in Frankfurt, Germany to a Jewish mother named, Karla. His journey of life began with misperception as to who his real father was; this is something that he died not knowing the actual facts. He was rumored to be the illegitimate child of an extramarital affair. Although he searched until the day of his death he never identified or met his biological father. â€Å"At this point I realized that his lifelong quest to find his father would remain unfilled (Friedman, 2000). He was given his mother’s first husband name, Salomonsen, however this was only a brief marriage and ended long before Erikson was conceived. After his birth, Erickson and his mother lived in Europe his first 3 years of life. During that time Erikson and his mother formed a bond that lasted him a lifetime. When Erikson was the age of 3 his mother remarried. His mother married Erikson’s pediatrician Dr. Theodore Homburger. Dr. Homburger did eventually adopt Eriks on and he was given the last name, Homburger. Once they were married they continued to build a family welcoming three daughter’s: Elna, Ruth, and Ellen. Growing up in a home with his family proved to be a challenge for Erikson because he never felt as though he was really part of this family. Erikson was raised Jewish, but due to the fact that he had blonde hair and blue eyes he was constantly picked on growing up. He felt very uncomfortable growing up and never liked traditional schooling, he was interested in
