LAN and WAN are types of networks.
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.
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.
|1||Definition||LAN stands for Local Area Network.||WAN stands for Wide Area Network.|
|2||Ownership||LAN is often owned by private organizations.||WAN ownership can be private or public.|
|3||Speed||LAN speed is quiet high.||WAN speed is lower than that of LAN.|
|4||Delay||Network Propagation Delay is short in LAN.||Network Propagation Delay is longer in WAN.|
|5||Congestion||LAN has low congestion as compared to WAN.||WAN has higher congestion than LAN.|
|6||Fault Tolerance||Fault Tolerance of LAN is higher than WAN.||Fault Tolerance of WAN is lower than LAN.|
|7||Maintenance||Designing and maintaining LAN is easy and less costly than WAN.||Designing and maintaining WAN is complex and more costly than LAN.|
