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 (e.g., token ring or Ethernet). Most Indiana University Bloomington departments are on LANs.
A WAN (wide area network), in comparison to a MAN, is not restricted to a geographical location, although it might be confined within the bounds of a state or country. A WAN connects several LANs, 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.
WAN. LAN is a short range connection, WAN is wide range.
absolutely wan. lan is used for a office or a building complex
LAN users get access to internet or can communicate with others LAN connected to WAN.
An LAN card is a must if you wish to connect to a LAN but it is not required for WAN
WAN requires the same technology as LAN.
Extranet is wan
if the LAN is connected to another LAN over a wide distance using point to point links then it becomes part of the WAN (but it doesn't become a WAN by itself).
Network B -- WAN Network C -- LAN Network A -- LAN
why the lan high speed than wan
wan wireless right?
ATM protocol is a WAN technology
From the user's point of view, accessing a LAN or WAN is the same. If packets need to be forwarded from a LAN via a WAN connection that is taken care of automatically by the router.
