Answer 1

Answer:

The ethernet protocol IEEE 802.3 is only meant for cable networks.

Explanation:

In this scenario, there are two types of networks, namely;

LAN and WLAN.

A LAN (local area network) is a network within a small area like a  building, i which its workstation are connected using cables. The cabled network instantly use a protocol called Ethernet also known as IEEE 802.3.

WLAN (wireless local area network) is a small area network just like the LAN, but the difference is that its workstation are connected wireless (without cable). wireless networks uses wifi or 802.11a/n/g to connect to the network.

So, the ethernet protocol represents the cabled network, Wifi represents the wireless network.
