Types network

There are three types networks:

1. Local Area Network

2. Metropolitan area network

3. Wide Area Network & Wireless Lans & Wans

1. Local Area Network: (LAN) Which is which is usually a small network forced to a small geographic area. An example of a LAN would be a computer network within a building. A LAN connects network devices over a relatively short distance. A networked office building, school, or home usually contains a single LAN, though sometimes one building will contain a few small LANs (perhaps one per room), and occasionally a LAN will span a group of nearby buildings.
2. Metropolitan area network: (Man) which is used for medium size area. examples for a city or a state. A WAN is a geographically-dispersed collection of LANs. A network device called a router connects LANs to a WAN. In IP networking, the router maintains both a LAN address and a WAN address.
3. Wide area network: A WAN differs from a LAN in several important ways. Most WANs (like the Internet) are not owned by any one organization but rather exist under collective or distributed ownership and management. Wireless LANs and WANs:- (WLAN & WWAN) are the wireless the same of the LAN and WAN.
