What in the lan for a small office, some user devices connect to the lan using a cable, while others connect using wireless technology (and no cable). which of the following is true regarding the use of ethernet in this lan?

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.
