Types of Networks

Networks can be classified as follows:

1. Local Area Network (LAN)
2. Wide Area Network (WAN)
3. Metropolitan Area Network (MAN)

Metropolitan Area Network (MAN)

In between LAN and WAN is the Metropolitan Area Network (MAN). A MAN is a network that covers an entire city, but uses LAN technology. Cable television networks are examples of MANs distributing television signals. The MANs we are interested in, carry information in the form of computer signals from one computer to another.
