LAN is short for Local Area Network which describe a group of computers, associated devices and also peripherals in limited area that are interconnected into a network.

Another definition of LAN (Local Area Network) is a high-speed data communication network that is used to connect devices such as computers, laptops, servers, printers, and other devices within a limited geographic area, such as a home, office, or campus.

What is LAN?

In a home, office, or school, for example, a Local Area Network (LAN) is a type of computer network that links computers and other devices within a specific geographic area. A local area network (LAN) enables inter-device communication and resource sharing, including the use of printers, internet connections, and files.

A LAN can incorporate two or three users working from home or thousands of users at the corporate headquarters. LANs are set up by homeowners and information technology (IT) administrators to enable resource sharing and communication between network nodes.

A LAN’s ability to connect users to internal servers, websites, and other LANs that are a part of the same wide area network is one of its main advantages (WAN). As a result, network users can collaborate and communicate more effectively.

The two main ways to enable LAN connections are Ethernet and Wi-Fi. Computers can communicate with one another using cables thanks to the Ethernet specification from the Institute of Electrical and Electronics Engineers (IEEE). In contrast, Wi-Fi uses radio waves in the 2.4 GHz and 5 GHz spectrum to wirelessly connect computers to LANs.
