A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. By contrast, a wide area network (WAN) not only covers a larger geographic distance, but also generally involves leased telecommunication circuits.

- Building technologies & automation
- Coverage area is generally a few kilometers.
- In LAN you can run the multiple devices to share a transmission medium.
- You can use the different topology mainly bus and ring in LAN.
- The communication quality is better IN LAN, the transmission error rate are low as compare to WAN.
- LAN support a variety of communications transmission medium such as a Ethernet cable (thin cable, thick cable, and twisted pair), fiber and wireless transmission.
- A LAN usually has low cost, installation, expansion and maintenance and LAN installation is relatively simple, good scalability.
