A local area network (LAN) connects computers and devices within a small geographic area like a home, school, or office using networking hardware like network cards, switches, and routers. Network cards connect devices to the network, switches connect network nodes, and routers join multiple networks and operate at the network layer. The TCP/IP protocol allows different operating systems and networks to communicate through the reliable TCP layer which transfers information across the network and the IP layer which identifies computers and transfers information to destinations.
