Question

What is a LAN?

Expert Solution
Step 1

Networking:

Networking refers to the process of transferring data and information among several people who reside at different geospatial locations. Also, it is possible to share software or hardware resources through a computer network.

A network can be constructed in multiple forms depending on the area covered and the number of people using the network:

  • Local Area Network
  • Metropolitan Area Network
  • Wide Area Network
  • Personal Area Network

 

Step 2

Answer:

A local-area network (or LAN) provides a smaller network coverage (up to 100 meters), mostly for connecting several devices within a room, an entire building, or a few buildings. Multiple LANs can be connected to construct a larger network.

Characteristics:

  • Fast data exchange
  • Low configuration cost
  • Easy physical construction
  • Available in different sizes
