A Local Area Network (LAN) is a group of computers and devices connected within a limited area, such as a home, school, or office building. It allows these devices to communicate and share resources, like files and printers, efficiently. LANs typically use wired connections, like Ethernet cables, or wireless connections, such as Wi-Fi, to link devices together. LANs are essential for enabling collaboration and resource sharing among users in close proximity. They can support various devices, including computers, smartphones, and printers, making it easier for people to work together. Common networking equipment used in LANs includes routers, switches, and access points.
