The acronym LAN stands for Local Area Network. A LAN is a network that connects computers and devices within a limited geographic area, such as a home, office, or campus, allowing them to communicate and share resources like files and printers. LANs can be wired, using Ethernet cables, or wireless, using Wi-Fi technology. They provide high-speed connectivity and are essential for enabling resources sharing and collaboration among users within a specific location. Additionally, LANs are foundational for larger networks, such as Wide Area Networks (WANs).
