Area Base of Computer Network • LAN • MAN • WAN
Types of Computer Networks • Local Area Networks (LANs) • within a building or campus • usually based on broadcast channels • often connected via gateways to wide area networks • Examples: (Fast)Ethernet, FDDI rings, Myrinet, ATM LANs • Bit rates: 10-1000 Mbps Computer Cable Computer (a) (b)
Type of Computer Networks • Metropolitan Area Networks (MANs) • covers area of a city • usually based on LAN technology • Examples: DQDB (Distributed Queue Dual Bus), cable television networks
Type of Computer Networks • Wide Area (Long Haul) Networks • may cover country, continent • Most communication links are point-to-point • usually irregular topology • usually organized as a “subnet” to which hosts have access. • switching elements are generically referred to as routers
