A local area network (LAN) is a network of computers and other devices that are connected within a limited geographical area, such as a home, office building, or campus. LANs allow users to share resources such as files, printers, and internet connections, as well as communicate with each other through email and messaging. LANs are typically faster and more secure than wide area networks (WANs) because they are confined to a smaller area and are not exposed to external threats from the internet. Some common types of LAN technologies include Ethernet, Wi-Fi, and Token Ring.
