What Is Computer Network?
In simple words, a computer network is a set of two or more connected computers. It helps devices to communicate with one another.
There are mainly three types of computer networks – Local Area Network – Metropolitan Area Network – Wide Area Network
Local Area Network
A LAN is a set of computers linked together in a small area such as a hospital, school, or apartment.
Metropolitan Area Network
MAN covers more extensive areas than LANs. Various LANs are linked through telephone lines in the Metropolitan area network.
Wide Area Network
Another robust computer network that allows long-distance data transmission is the WAN.
