What is Local Area Network LAN
A LAN is a local area network that means it is spread over a small area, such as a home, a school, sometime maybe a small group of buildings. In TCP/IP networking, a LAN is often but not always implemented as a single IP subnet. They are often run by a single person and tend to use Ethernet and token ring connectivity systems.
Normally a LAN can handle up to 1024 computers but practically the limit is 256 computers because of the routers and in reality even more less computers are connected in the LAN because of the need.
A basic LAN consist many components and some of them are listed below:
- Two or more computers.
- Network Interface card or LAN Card in each PC.
- Ethernet cable (Cat5, UTP/SPT) cable to connect the two computers.
- A hub, switch or router to route or direct the network traffic.
- Software for the communication/computer networking
