A Local Area Network (LAN) is a group of computers or other devices interconnected within a single, limited area, typically via Ethernet or Wi-Fi.
A LAN is a computer network that consists of access points, cables, routers, and switches that enable devices to connect to web servers and internal servers within a single building, campus, or home network, and to other LANs via Wide Area Networks (WAN) or Metropolitan Area Network (MAN). Devices on a LAN, typically personal computers and workstations, can share files and be accessed by each other over a single Internet connection. A router assigns IP addresses to each device on the network and facilitates a shared Internet connection between all the connected devices.
