LANs, WANs, and the Internet

LANs and WANs

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.
