                          The process of connecting computers and peripheral devices with each other for the
                         purpose of exchange data is called computer networking.
                          Network refers to an inter-connected group of people, objects, companies, computers,
                         etc.
                          There are various types of devices such as Network Interface Card (NIC), Hub, Switch,
                         Router, Modem, Network Cable and Gateway.
                          The different types of networks are PAN, CAN, LAN, MAN and WAN.
                          Topology refers to the geometric arrangement of computers or nodes in a network.

                          Various types of topologies used in a network are bus, star, tree, ring and mesh.
                          There are two types of computer network architectures—peer-to-peer network and
                         client-server network.
                          Protocol is a set of rules that governs the communication between the computers over
                         a network.
