Network :: essays research papers

A computing device meshing is a sort out of interconnected computers that preempt accomplish many important tasks. To define computer networking you should define networks. A network is composed of two or flock 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 buttocks consist have an IBM 3270 terminal and accompanying central processing unit, to a stand-alone computer. The computer is usually an IBM PC personal computer or clone licenced 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 find out 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 communications protocol (TCP/IP). TCP/IP is the protocol of the Internet. Internet is actually the short bo unce 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 hap 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 unhorse (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 force out 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.
