lan meaning

Lan meaning is local-area network (LAN) a computer network that spans a relatively small area. Most often, a LAN is confined to a single room, building or group of buildings, however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves.

A local-area network connects the computer hardware in a localized area such as an office or home. Typically,LANs use wired connections to link the computers to each other and to a variety of peripheral devices such as printers. users can communicate with each other by chat or email.

Generally, LANs transfer data at much faster rates than telephone line connections, but are limited in the number of computers they can support and the distances they can transfer data. LANs can connect to other LANs over telephone lines, satellites or radio waves, creating what's known as a wide-area network (WAN). The world's largest WAN is the Internet. 

Generally, LANs involve a lot of wires and cables that can prove to be a nuisance. Wireless LANs (WLANs) carry out the same functions as a LAN, but without the clutter.
