The acronym "LAN" stands for Local Area Network. This refers to a network that connects computers and devices within a relatively small geographic area, such as a home, school, or office building. LANs enable high-speed data transfer and resource sharing among devices, such as printers and file servers. They can be wired, using Ethernet cables, or wireless, using Wi-Fi technology. The flexibility and efficiency of a LAN facilitate collaboration, communication, and network access, making it an integral component of modern computing environments.
