What is computer network?

In this session, we discuss about computer network which is using millions of people in practical life. To understand computer network first we need to clear our mind about network “what is network?” In technical term, communication of two or more nodes in a path is known as network and combination of multiple of network is called sub-network.

Now we easily define computer network, number of computers connected in a plate-form is known as computer network. Computer network can easy our lives in communication field with the passage of time. Now a days computer networking can have multiple types of communication in which includes LAN, MAN and WAN. Without these terms computer networking cannot have any able to do work.

LAN is known as local area network.  LAN is defined as computers connected in any geographical area like school, college, forums, offices or closely communicated computers.

MAN is known as Metropolitan Area Network. MAN in which multiple LAN are interconnected and is greater than local area network but smaller than wide area network.

WAN is stands by wide area network. Numbers of computers are widely connected over a large geographical area known as WAN. Communication of WAN can make an easy way to communicate one person to other person in a small time on two large geographical areas.
