A Local Area Network (LAN) is a computer network that spans a relatively small geographic area, typically confined to a single building, office, home, or a group of nearby buildings. LANs are designed to facilitate communication and resource-sharing between devices such as computers, printers, servers, and other networking devices within a limited area.
LANs are often privately owned, controlled, and managed by an organisation or an individual. This allows the administrators to regulate access, security, and network management policies within the LAN.
LANs are the foundation of many modern business and home networks. They enable the sharing of resources, collaboration among users, and the efficient transfer of data and information. In larger networks, LANs may be interconnected through routers and switches to form larger networks, such as Wide Area Networks (WANs), allowing communication across broader geographical areas.
