LAN(Local Area Network)

LAN stands for Local Area Network. It is used to connect computers in a room or a building. Its range is low. It covers less area. Mostly LAN is used in office or a department.

LAN provides a very fast speed and good quality. That’s why LAN is mostly used. Maximum speed of LAN is 1000 Mbps. LAN has a higher data transfer rate. Computers are connected with each-other via Cables.
or

LAN has smaller coverage range within the house or office premises or can at least connect from one building to the nearby building. Most of the LANs usually will have about 10 to 100 users. Multiple users in LAN time share the system. LAN has been developed to allow sharing of common resource such as printer,harddisk and modem to more than one PCs. In this scenario PC connected with common resource is called as controller through which all the users will access the resource. As the days evolve people started using LAN for e-mail system for corporate network, here one system is configured as server storing mail boxes of all the users.

Latest advancement in the LAN technology supports data rates which range from 10 Mbps, 100 Mbps till 1Gbps. LAN is designed initially as per 802 standards, later various wireless standards are evolved such as IEEE 802.11a, 11b, 11g and 11n. Currently research is to finalize products supporting IEEE 802.11ac and 802.11ad supporting very high data rates.

Advantages of LAN:

There are some advantages of LAN. These are as follows:

1. Fast Data transfer rate.
2. Less possibility of errors.
3. Less expensive.
4. Best method of Communication.
5. Mostly Used Network.
