A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, or office building. It typically relies mostly on wired connections for increased speed and security and allows devices on the network to communicate with each other.
A LAN consists of two or more computers connected together with network cables and connected to a router or switch. The router or switch serves as the gateway to the network and directs data between computers. The computers on the network can share resources such as printers and scanners, as well as data and applications. The computers can also access the Internet, although this is not a requirement.
A LAN can be configured in many different ways and is often customized to meet the specific needs of the organization or user. The most common type of LAN is an Ethernet-based network that uses Ethernet cables and switches to connect computers. Other types of LANs include wireless LANs (Wi-Fi), token ring networks, and fiber-optic networks.
