Difference between LAN and WAN

Computer EngineeringComputer NetworkMCA

LAN and WAN are types of networks.

LAN - Local Area Network

A Local Area Network (LAN) is a private network that connects computers and devices within a limited area like a residence, an office, a building or a campus. On a small scale, LANs are used to connect personal computers to printers. However, LANs can also extend to a few kilometers when used by companies, where a large number of computers share a variety of resources like hardware (e.g. printers, scanners, audiovisual devices etc), software (e.g. application programs) and data.

WAN - Wide Area Network

A Wide Area Network (WAN) is a much larger network than LAN and MAN. It often covers multiple contries or contenants. It is quiet expensive and a single organization may not have own it. Satellite is used to manage WAN.

Following are the important differences between LAN and WAN.

1DefinitionLAN stands for Local Area Network.WAN stands for Wide Area Network.
2OwnershipLAN is often owned by private organizations.WAN ownership can be private or public.
3SpeedLAN speed is quiet high.WAN speed is lower than that of LAN.
4DelayNetwork Propagation Delay is short in LAN.Network Propagation Delay is longer in WAN.
5CongestionLAN has low congestion as compared to WAN.WAN has higher congestion than LAN.
6Fault ToleranceFault Tolerance of LAN is higher than WAN.Fault Tolerance of WAN is lower than LAN.
7MaintenanceDesigning and maintaining LAN is easy and less costly than WAN.Designing and maintaining WAN is complex and more costly than LAN.
