A network that connects devices within a limited geographical area, such as a home or office, is called a local area network (LAN). LANs allow for high-speed data transfer and resource sharing, including printers, files, and Internet access among connected devices. Typically utilizing Ethernet or Wi-Fi technologies, LANs enhance productivity by facilitating communication and collaboration among users in close proximity. Security features such as firewalls and access controls are often implemented to protect the network from unauthorized access. Overall, LANs play a crucial role in enabling efficient networking in localized environments.
