How Computer Networks Work

How Computer Networks Work - The computer network is a system that consists of computers and other network devices that work together to achieve a common goal. The purpose of the network is the computer:
 
Sharing of resources: for example, shared use of printers, CPU, memory, hard drive

The principle works, first sender to send information to the receiver via a signal encoded protocol that converts the digital signal into an analog signal and then transmitting the signal through the media and through the second protocol decoded back into digital signals before going into the receiver.

How Computer Networks Work

There are four main components that are on a network:

1. Sender (sender of data information) 
2. Protocol (which encode and decode the data information) 
3. Transmission media (data transfer medium), and
4.  Receiver (receiving data information).

The working principle above can in analogy when the Japanese and the English were chatting over the internet. When the Japanese typing a message in Japanese language the message is first converted by the protocol into English so that English people can receive the message in English and vice versa when the British reply to the message is the message the Japanese English language will be changed by the protocol first become a Japanese language prior to the Japanese people. So in this case protocols can be termed as a translator of information data.
