LAN

=LAN=

LAN, standing for local area network, is a computer network that connects to all computers in a building, house, or school.

LAN's have faster data-transfer rates than WANs.Its signal also doesn't extend as far as a WANs and unlike a WAN a LAN does not need a cord or leased telecommunication line for sending messages. LANs are useful for shring things like games, files, and printers. LANS are usually built whith Ethernet cables and other inexpensive harware.Large LANs can connect to as many as thousands of computers (in the same location or building) and small(est) home LANs connect to exactly two computers.Many LANs are divided into subnets, allowing the computers to connected to the internet through one shared network address.

Small LANs usually have one or more connected switches, and at least one switch is connected to a router, cable modem, and ADSL modem (all hardware that helps forward and make it easier to forward info.) for internet access. Larg LANs have many different network devices like swtiches, firewalls, router, ect. Unlike small LANs, large LANs use repreating links with switches that use spanning tree control to prevent loops from bridged LANs (devices that are up to the bridge's standard or IEEE 802.1D standard).
