Metropolitan-area network (MAN): A MAN is a network that is
extended to cover multiple locations within a slightly larger distance
than a CAN. A classic example of a MAN is the cable network in a city.
Figure 17-4 shows an example of a MAN that connects various network
segments.Figure 17-4 Metropolitan-Area Network
Wide-area network (WAN): A WAN covers an even larger
geographic area than a MAN. The connections are through public
networks, such as the telephone system, microwaves, satellite links, or
leased lines. Figure 17-5 shows an example of a WAN that connects
various remote offices with the headquarters.
