Short for Metropolitan Area Network, a data network designed for a town or city. In terms of geographic breadth, MANs are larger than local-area networks (LANs), but smaller than wide-area networks (WANs). MANs are usually characterized by very high-speed connections using fiber optical cable or other digital media.

Stands For
Local Area Network
Wide Area Network
Local areas only (e.g., homes, offices, schools)
Large geographic areas (e.g., cities, states, nations)
LAN (Local Area Network) is a computer network covering a small geographic area, like a home, office, school, or group of buildings.
WAN (Wide Area Network) is a computer network that covers a broad area (e.g., any network whose communications links cross metropolitan, regional, or national boundaries over a long distance). 
High speed (1000 mbps)
Less speed (150 mbps)
Data transfer rates
LANs have a high data transfer rate.
WANs have a lower data transfer rate compared to LANs.
The network in an office building can be a LAN
The Internet is a good example of a WAN
Tend to use certain connectivity technologies, primarily Ethernet and Token Ring
WANs tend to use technologies like MPLS, ATM, Frame Relay and X.25 for connectivity over longer distances
One LAN can be connected to other LANs over any distance via telephone lines and radio waves.
Computers connected to a wide-area network are often connected through public networks, such as the telephone system. They can also be connected through leased lines or satellites.
