Suppose two persons that have data stored on some media, say hard drives. If the two persons need to share this data with each other, what will they do?
This question is the basis on which the networking principle is built. 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. gtamp.
