Question

What are the differences between a wired LAN and a wireless LAN and state their advantages and disadvantages?

Answer 1

Wired LAN:
- A wired LAN uses physical cables such as Ethernet cables to connect devices to a network.
- The advantages of wired LANs include faster and more reliable data transfer, less interference from other wireless signals, and higher security as it is harder to tap into a physical cable than a wireless signal.
- The disadvantages of wired LANs include the cost and hassle of installing and maintaining cables, as well as the limited mobility of devices that are connected via cables.

Wireless LAN:
- A wireless LAN uses radio waves to connect devices to a network without the need for physical cables.
- The advantages of wireless LANs include the convenience and ease of use, as devices can connect wirelessly without the need for cables and can easily move around within the signal range.
- The disadvantages of wireless LANs include slower data transfer speeds, less reliable signal quality, and more susceptibility to interference from other wireless devices or physical barriers such as walls. There is also a greater security risk as wireless signals can be easily intercepted or hacked if not properly secured.
