Computer Networking: Definitions And Basics

The two persons can send the data to each other by copying it to movable drive say flash memory and giving it to each other. This can be well if it will not be happening continuously. But what if the two persons need to send data every day or even every hour? It will be difficult to send it to each other especially if they remote from each other.

The idea of networking has been arisen from such cases. Instead of sending data between two or more people on movable devices such as floppy disks, they can easily connect their computers to each other. Every person who wants to transfer the data to his friend can easily transfer it through the network. Mainly the network will be composed of a set of computers and a printer. This set of computers will be responsible for sending the data to each other. One computer also may use the printer to print documents. If the network looked like this, it will be called peer to peer. In this scheme, all computers are the same and have equal processing power. The information is also distributed across them equally. There is no device that has more data in its hard drive.
