Size and scope. A LAN is a Local Area Network, and is usually confined to a single building. A MAN is a Metropolitan Area Network and would cover multiple buildings in a city area. A WAN is a Wide Area Network and can cover any size geographical area.
A MAN is a relatively new class of network, it serves a role similar to an ISP, but for corporate users with large LANs.They typically use wireless infrastructure or Optical fiber connections to link their sites. 1.The network size falls intermediate between LANs and WANs. A MAN typically covers an area of between 5 and 50 km diameter. Many MANs cover an area the size of a city, although in some cases MANs may be as small as a group of buildings or as large as the North of Scotland. 2.A MAN (like a WAN) is not generally owned by a single organisation. The MAN, its communications links and equipment are generally owned by either a consortium of users or by a single network provider who sells the service to the users. This level of service provided to each user must therefore be negotiated with the MAN operator, and some performance guarantees are normally specified. 3.A MAN often acts as a high speed network to allow sharing of regional resources (similar to a large LAN). It is also frequently used to provide a shared connection to other networks using a link to a WAN.

A network that (a) is composed of different interconnected computer networks and (b) covers an unlimited geographical area. Note: Loosely synonymous with an internet (as opposed to the Internet (with an uppercase "I"), which designates one specific network).
A computer network that spans a long distance and uses specialized computers to connect smaller networks.
The term "geographical area" is somewhat ambiguous. Generally speaking, there are 4 types of networks PAN (Personal Area Network), covers a short range, perhaps 20 foot diameter. This is what a bluetooth network usually is. LAN (Local Area Network), covers a building, and perhaps nearby buildings. A common stand alone office network is one of these. MAN (Metropolitan Area Network), covers a wider area then a LAN, but less then a WAN. This is not a very common term, but is usually something along the lines of a business that has two buildings in the same city, but not very close to each other. WAN (Wide Area Network), any large network span. The internet itself is a form of WAN.
Neither, those terms refer to smaller networks, a LAN being "Local Area Network" used in residential or commercial facilities and a WAN is a Wide Area Network, for instance one that covers an entire town/City, these almost always connect to the greater, Internet
Computer networks can be classified based on their size and scope as follows: Local Area Network (LAN): Covers a small geographic area like a single building or campus. Wide Area Network (WAN): Spans over a large geographical area, often connecting multiple LANs. Metropolitan Area Network (MAN): Intermediate in size between LANs and WANs, covering a city or metropolitan area.
Wide area network (WAN) that is usually a larger network that covers a large geographic area.
Metropolitan Area Network (MAN) covers a larger geographical area than a LAN but smaller than a WAN. It typically connects multiple buildings within a city or town. MANs provide high-speed connectivity and support a larger number of users compared to LANs.
Communication network can be generally viewed as Switched & Broadcast.In switched network comes Circuit & Packet Switched network.Circuit Switched Network are used by Telphone,GSM.Packet Switched network are further sub divided into Datagram & Virtual Circuit.Datagram circuit followed by Internet,IP network whereas Virtual circuit example is ATM .
The 802.11 wireless networks provide wireless access on a local network that generally covers a small area. Cellular WANS, meanwhile, are designed to cover city-wide and even global areas.
A group of two or more computer systems linked together in the same building is called a local area network (LAN). LANs allow the connected devices to share resources like printers, files, and internet connectivity.
Lan is a local network such as inside a house or building, or a wireless covering an area locally. Wan is a wide area network such as the Internet. This network covers a large area (can include the world). Wan's consist of many local area networks linked together.
