Suppose two people, claim hard drives, have data stored on some internet. If the two people need to share the data with each other, what are they going to do?
That problem is the basis on which the theory of networking is based. By copying it to mobile drive, the two people will give the data to each other saying flash memory and giving it to each other. It can be perfect if it is not going to happen indefinitely. But what if it takes the two people to send data every day, or even every hour? It’ll be hard to submit it to each other particularly if they’re distant from each other.
From these cases emerged the concept of networking. They can easily link their computers to each other instead of transmitting data between two or more people on mobile devices such as floppy disks. Anyone wanting to transfer the data to their friend can easily pass it over the network.
So how will the data be transmitted over the network? The data can be easily transmitted simply by connecting computers of different persons to one another by means of cables. The internet would also be cables rather than handheld devices, but it can also be wireless devices. The wireless computer sends the data by electromagnetic waves in the air. Unless the data is transmitted on wires, it would be electric pulses.
Networks can in reality be used not only to exchange data but also to exchange devices like printers and CD-ROM. One consumer on a floor can use a printer that is connected through the network to another device on the other floor. The same holds for CD-ROMs. It must be configured via the operating system on both computers. This networking benefit makes it useful for people to use remote devices at their office. This also reduced the expense as all network members are used on printer or on one CD-ROM.
The network is composed primarily of a set of computers and a printer. A group of computers must give the data to each other. One machine can also print documents using the printer. If the network looked like that, then peer to peer would be called. All machines are the same in this system, and have similar computing power. The knowledge is spread fairly by them, too. There is no device on its hard drive which has more data.
At the other hand, if there is at least one computer in the network that has more data stored and more power and speed of operation, then the system is called server-based networking. The server will be called the computer which has the more data storage and the greater processing power. This scheme can also be described as a model based on a client-server since the other computers in the network with normal processing power are viewed as clients requesting data from the server. The internet is built over this scheme where the clients are the home computers and the servers are called the computers which serve them.
