- What LAN is
LAN stands for local area network. A local area network represents a small or large area such as a building or even a class room .All the computers within a designated area are linked to the LAN and can access a common device such as a printer.
- Where LAN is used
Local area networks are used in many different ways and in many different scenarios. For instance LAN can be within a large office building with more than thirty computers all in the same LAN. However LAN can be accommodated to smaller areas, such as setting up a LAN connection between two playstations for establishing a system link. This permits LAN to be used from small personal business's to large corporations. But requires proper installations and maintenance to allow LAN to properly run in a large scale operation. instance LAN can be within a large office building with more than thirty computers all in the same LAN.

- Why LAN is used
LAN is used depending on the application that is needed. Using LAN for an entire company that is spread word wide is just not practical. However were LAN becomes useful is when it allows a certain number of computers to all belong to the same network and communicate within that network. This allows LAN to become a more accessible and quicker way of communication, with very little chance of any delay. Although this is not to say a user cannot experience delay through LAN. As the number of computers increases on a certain LAN, the speed of the resulting connection begins to become diluted.
- An alternative to LAN
An alternative to LAN would be WAN, WAN stands for wide area network and in principle works like LAN. But on a much larger scale. WAN also incorporates many LAN connections and can identify with the internet. However LAN and WAN do have there differences in speed, reliability and access.
