In other words, Network is the interconnection of two or more computers for the mutual exchange and sharing of information or other resources. Under computer network, there is mutual sharing of resources, so that data and information are equally accessible from one computer to another.
There are mainly 3 types of computer networks: LAN, WAN and MAN. Apart from this, there are some other PAN and HAN.
We have listed here top computer networks questions answers, which covers all important networking chapters like Topologies, Transmission modes, Categories of Network, OSI model, IP classes etc.
You should practice these computer networking one line questions for your competative exams.
