LAN Interface Overview
This section provides an overview of Local Area Networks (LANs) that
use Transmission Control Protocol/Internet Protocol (TCP/IP),
including:
• Typical Network Topologies
• LAN Hardware Architecture
Typical Network Topologies
LANs using TCP/IP can be divided into two categories: Site LANs and
Private LANs.
Site LAN Topology
A Site LAN can be a workgroup LAN, Intranet, or enterprise
(corporate) LAN. Typically, a site LAN includes several PCs, routers,
and servers. The LAN network is usually administered and controlled
by a system administrator (or network administrator) who installs,
monitors, and troubleshoots the network.
