Know About Computer Network

Computer network is a collection of computers, printers and other equipment are connected in one unit. Information and data moving through wires or wireless computer network allowing users to exchange documents and data, print on the same printer and together using hardware / software that is connected to the network. Each computer, printer or peripherals connected to the network are called nodes. A computer network can have two, tens, thousands or even millions of nodes.

The concept of computer network was born in the 1940s in America of a development project in Model I computer at Bell labs and research group led by Harvard University professor H. Aiken. In the beginning the project merely wanted to use a computer device that must be used together. To do some process without wasting lots of time was made blank successive process (batch processing), so that multiple programs can run in a computer with the rules of the queue.

In 1950's when the types of computers began to swell until the creation of a super computer, a computer must serve multiple terminals (see Figure 1) was found for the concept of time-based distribution process known as TSS (Time Sharing System), then for the first time form network (network) was applied to the computer. In the TSS system several terminals connected in series to a host computer. In the process of TSS now appears a combination of computer technology and telecommunications technology that was originally developed on their own.
