CABLING LAN AND WAN
Overview
•Even though each local-area network is
unique, there are many design aspects that
are common to all LANs. For example, most
LANs follow the same standards and the
same components. This module presents
information on elements of Ethernet LANs
and common LAN devices.

•There are several wide-area network (WAN)
connections available today. They range
from dial-up to broadband access, and differ
in bandwidth, cost, and required equipment.
This module presents information on the
various types of WAN connections.

•Various symbols are used to represent
media types. Token Ring is represented by
a circle. Fiber Distributed Data Interface
(FDDI) is represented by two concentric
circles and the Ethernet symbol is
represented by a straight line. Serial
connections are represented by a lightning
bolt.
