A computer network is a group of interconnected computers that can accomplish many important tasks. To define computer networking you should define networks. A network is composed of two or people or objects, using a common language, and they have something to share. In computer networking the two or more objects are the computer or terminal. This can consist; have an IBM 3270 terminal and accompanying mainframe, to a stand-alone computer. The computer is usually an IBM PC personal computer or clone licensed copy of a PC, usually cheaply made. The common language or protocol is necessary for the communicators to be able to understand each other. We take for granted simple things like who talks first, how long they talk, and how to end a conversation. A protocol addresses these and more. The common protocol is Transmission Control Protocol (TCP/IP). TCP/IP is the protocol of the Internet. Internet is actually the short form of the word Internet work. Internet work means a network of networks. At one time, all of the different networks used different protocols. A user could talk to others on their network, but not to someone on a different network. The protocol TCP/IP solves this problem. It is what allows a person on one network to communicate with a person on a different network.

When I mentioned something to share in the network definition, it can be anything, an idea, document, or greeting. Networking allows use of applications on other computers, electronic mail (email), and real time discussions in chat rooms. The types of networks are classified as distributive or centralized. In a centralized network, processing occurs at one place and requests are made of the processing from terminals. A mainframe computer with attached terminals is a great example of centralized network. The terminals communicate with the mainframe to accomplish tasks. A distributive network spreads processing power to the individual computers. Networked PCs are a great example. Tasks are accomplished at the computer and at other computers using communication. In the definition of a network the computer hardware is considered part of the user in this definition. The hardware used to connect to other computers is considered part of the protocol.

  • O-Lan Thesis

    938 Words  | 2 Pages

    The bitter cold bit against the starved girl’s skeletal body. She was tired. Her parents discussed ways to get to good lands. They told her the only way to have a better life was to sell her into slavery. The girl, only ten years old was silent. She dreamed of fine clothing and good food. The girl went to the House of Hwang. She was too ugly to be in sight; she was kept in the scullery. All dreams of any kind were lashed out of her young mind. Mistreated, beaten, and underestimated, young O-lan learned to work hard and became resigned to her fate. One day, the Old Mistress summoned her and told her that she was to be married to a poor farmer. The other slaves scoffed, but O-lan was grateful for a chance to be free - they married. O-lan vowed to return to the great house one day in fine clothing with a son. Her resolve was strong; no one could say otherwise. Her years of abuse as a slave had made O-lan wise, stoic, and bitter; whether the events of her life strengthened or weakened her is the question.

    To attempt to define a network in a few sentences would be a fool’s errand. A network could be seen as simply a grid of interconnecting connections between multiple bodies. However when this vision is applied to real-world systems, they all start to differ. There is not anything that exists in the universe that is not part of a network. A network is the result of different parts or members which have similarities in parts of their identity. This similarity that they have in common, they will also have with other bodies forming a network between them. Most of these factors of identity are different from those of most others. As a result, each factor will be in common with different other members of different networks. Each factor includes this body in a multitude of networks. This means that no one thing is in one and only one network, but is included in many.

  • Summary Of Connectivity And Its Discontent

    288 Words  | 1 Pages

    In the article, “Connectivity and Its Discontent,” by Sherry Turkle, the author discusses the relationship between human beings and technology. First, the author begins the article by explaining why people choose to text message because it is easier compared to face to face contact. On the other hand, technology can prevent a person from feeling lonely and having power to control a conversation. In addition, the author states how a person can multitask while communicating with someone on video chat, yet a person can feel at times guilt-ridden by ignoring a person sending emails while socializing on video chats. Meanwhile, Turkle contends that some people are choosing to be closer to their devices by focusing on themselves and not show consideration

  • Peer to Peer or Server Based Networking

    2177 Words  | 5 Pages

    A network can be based on either a peer-to-peer level or server-based, also referred to as domain-based. To distinguish the difference, a peer-to-peer network, also known as a workgroup, is a network in which a group of computers are connected together to share resources, such as files, applications, or peripherals. The computers in a peer-to-peer network are peers to one another, meaning no single computer has control over one another. There is also no central location for users to access resources, which means that each individual computer must share their files in order for other computers to have access (Muller, 2003, p.411). “In a peer-to-peer environment, access rights are governed by setting sharing permissions on individual machines.” (Cope, 2002) On the other hand, in a domain-based network, the computers connected together are either servers or clients. All of the other computers connected to the network are called client computers. The server is a dedicated machine that acts as a central location for users to share and access resources. The server controls the level of authority each user has to the shared resources. When logging on to the network, users on client machines are authenticated by the server, based on a user name and password (Lowe, 2004, p.13).

    TCP/IP is a network model which enables the communication across the Internet. The most fundamental protocol on which the Internet is built. This is made up of the 2 common networking protocols, TCP, for Transmission Control Protocol, and IP, for Internet Protocol. TCP maintains and handles packet flow linking the systems and IP protocol has the ability to handle the routing of packets. However The TCP/IP stack consists of 5 layers first being application layer, the transport layer, then the network layer, the link layer and finally the physical layer. The assignment focuses on the three middle layers and is divided into five parts. Firstly explaining how the TCP and UDP the most vital protocols needed to deliver and communicate.

    Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.

    In recent years, network coding [1], [2] has been considered as an auspicious information network paradigm for augmenting the throughput of multiple unicast networks [5]. The pioneering researches of network coding were undertaken by R. Ahlswede, N. Cai, S.-Y.R. Li and R.W. Yeung. Their discovery, which was first introduced in [1][2], are considered to be the crucial breakthrough in modern information theory and the time of its appearance, is recognized as the beginning of a new theory-Network Coding theory. In these elegant, succinct articles, within the purview of rigorous mathematics, the glimmering of an optimal network protocol for multiple unicast network was introduced in which the key idea is considering digital information as wave [riis].

  • The Internet

    In 1973, the U.S. Defense Advanced Research Projects Agency (DARPA) initiated a research program to investigate techniques and technologies for interlinking packet networks of various kinds. The objective was to develop communication protocols which would allow networked computers to communicate transparently across multiple, linked packet networks. This was called the Internetting project and the system of networks which emerged from the research was known as the "Internet." The system of protocols which was developed over the course of this research effort became known as the TCP/IP Protocol Suite, after the two initial protocols developed: Transmission Control Protocol (TCP) and Internet Protocol (IP). (I got my information for the history of the internet at www.isoc.org In 1986, the U.S. National Science Foundation (NSF) initiated the development of the NSFNET which, today, provides a major backbone communication service for the Internet. With its 45 megabit per second facilities, the NSFNET carries on the order of 12 billion packets per month between the networks it links. The National Aeronautics and Space Administration (NASA) and the U.S. Department of Energy contributed additional backbone facilities in the form of the NSINET and ESNET respectively. In Europe, major international backbones such as NORDUNET and others provide connectivity to over one hundred thousand computers on a large number of networks. Commercial network providers in the U.S. and Europe are beginning to offer Internet backbone and access support on a competitive basis to any interested parties.
