LAN, WAN and MAN
LAN - Local Area Network
WAN - Wide Area Network
MAN - Metropolitan Area Network
Residences typically employ one LAN and connect to the Internet WAN via an Internet Service
Provider (ISP) using a broadband modem. The ISP provides a WAN IP address to the modem, and all of the computers on the home network use LAN (so-called private) IP addresses. All
computers on the home LAN can communicate directly with each other but must go through a
central gateway, typically a broadband router, to reach the ISP.
LAN - Local Area Network
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. In TCP/IP networking, a LAN is often but not always implemented as a
single IP subnet.
In addition to operating in a limited space, LANs are also typically owned, controlled, and
managed by a single person or organization. They also tend to use certain connectivity
technologies, primarily Ethernet and Token Ring.
WAN - Wide Area Network
As the term implies, a WAN spans a large physical distance. The Internet is the largest
WAN, spanning the Earth.
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.
MAN - METROPOLITAN AREA NETWORK
MAN are basically larger versions of LANs. They typically cover a city.
Regional network, fast, for example, a wider area covering the city in general type of backbone network distances up to tens of kilometers.
e.g. a company in the same locality in the local area networks constitute a regional network

I like the Information that you described about the LAN, MAN and WAN. I have also watched the Video and it's very good. Good Job dear keep it up and keep posting some more technical information.
Thanx for the comment... And i would keep posting these kind of information which is helpful for others!!!
Hello, thank for your informative sharing. I'm studying about networking and it's very helpful and easy to learn because learning with video is interactive study. Thank you.
A little writting about technology
