Answer:
The ethernet protocol IEEE 802.3 is only meant for cable networks.
Step-by-step 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.
