These networks are categorized according to the size and area such as Local Area Networks (LAN), Wide Area Networks (WAN), Metropolitan Area Networks (MAN) and Personal Area Networks (PAN). The networking hardware mostly contains wires, network cards and a hub. The network cards are needed in order to understand what one computer is saying to another computer.

Network cards contain a distinctive MAC address to recognize computers on a network. Hubs link every computer in the network. Hubs might also be used to link another hub to extend the networking. It is the job of the networking expert to maintain the networks and keep them running. The experts are being called to protect private, organization and government information by frequently altering security processes.
