Introduction to LAN ProtocolsWhat Is a LAN?
Introduction to LAN ProtocolsWhat Is a LAN?A LAN is a high-speed data network that covers a relatively small geographicarea. It typically connects workstations, personal computers, printers, servers, and other devices. LANs offer computer users many advantages, including shared access to devicesand applications, file exchange between connected users, and communication betweenusers via electronic mail and other applications.

The following figure illustrates how several popular LAN protocols map to theOSI reference model.Popular LAN Protocols Mapped to the OSI Reference Model
