Network :: essays research papers

A electronic computer network is a group of inter concerned computers that force out implement many important tasks. To define computer networking you should define networks. A network is composed of two or people or objects, employ a common language, and they bewilder something to sh be. 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-al nonpareil computer. The computer is usually an IBM PC personal computer or cl champion licensed copy of a PC, usually cheaply made. The common language or protocol is requisite for the communicators to be able to understand each other. We take for granted artless things like who lambasts 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 profit. Internet is actually the short form of the word Int ernet work. Internet work means a network of networks. At one clock time, all of the diverse networks used diametric 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 outer space and requests are made of the processing from terminals. A mainframe computer with machine-accessible 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.
