When a group of computers are linked together, it is called a network. A network allows computers to communicate and share resources such as files, printers, and internet connections. There are different types of networks, including local area networks (LANs) which are confined to a small geographic area, and wide area networks (WANs) which can span across cities or even countries. Networking protocols like TCP/IP govern how data is transmitted and received within a network.
