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
