Local Area Network
local area network (LAN) is a computer network covering a small geographic area, like a home, office, or group of buildings. Current LANs are most likely to be based on Ethernet technology, running at 10 Mbps, 100 Mbps, or 1 Gbps, or on Wi-Fi technology. Each node or computer in the LAN has its own computing power but it can also access other devices on the LAN subject to the permissions it has been allowed. These could include data, processing power, and the ability to communicate or chat with other users in the network.
