Local Area Networks (LANs) are a network infrastructure that spans a small geographical area. Specific features of LANs include:
LANs interconnect end devices in a limited area such as a home, school, office building, or campus.
A LAN is usually administered by a single organization or individual. The administrative control that governs the security and access control policies are enforced on the network level.
LANs provide high speed bandwidth to internal end devices and intermediary devices.
