Difference between LAN'S, WLAN'S AND WAN'S.

The differences between these is:

LAN'S: A **LAN** (local area network) is a group of computers and network devices connected together, usually within the same building. By definition, the connections must be high speed and relatively inexpensive.

WLAN'S:
 * WLAN**s (wireless local area network**)** provide wireless network communication over short distances using radio or infrared signals instead of traditional network cabling. A WLAN typically extends an existing wired local area network.

WAN's: A **WAN** (wide area network), connects several LAN's (local area network) and may be limited to an enterprise (a corporation or an organization) or accessible to the public. The technology is high speed and relatively expensive. The Internet is an example of a worldwide public WAN.

So the differences between these is that:


 * A LAN is a local area network. specialises in only local area networking.


 * A WLAN is a wireless local area network. Specialises in network communications over short distances and extends an existing local area network.


 * A WAN is a wide area network.Specialises and connects many local area networks put together.
