                   ▶   A computer network is a collection of computers and peripheral devices (the network components) connected
                      by communication links (wired or wireless) through which data is transferred in the form of signals.

                   ▶   The components needed for a network are Network Interface Card, hub or a switch, router, modem,
                      networking cable, gateway, etc.
                   ▶   Based on the architecture, networks are classified into client/server network and peer-to-peer network.

                   ▶   Topology means the arrangement of computers in a network. The five basic topologies used for creating a
                      network are Bus, Ring, Star, Tree, and Mesh.
                   ▶   Protocols are rules and standards that are to be followed to ensure secure transfer of data from one

                      computer to another over the Internet.
