Answer:
Physical and data link layer.
Explanation:
The ethernet cable is used at the physical layer. The physical layer consists of hardware components. This layer is responsible for transmission of data bits between two nodes via a physical wire. The data link layer provides the means in which data packets are transmitted from one node to another.
Suppose two computers (A & B) are directly connected through Ethernet cable. A is sending data to B, the packets would be sent from computer A to computer B if computer B is free if not it would wait until computer B is not transmitting before it can start sending data packets to computer B.
the answer is virus scanner which is not hardware but software because if you didn't know hardware is stuff like a monitor a mouse a battery a case that's all stuff you can generally touch even the hardware inside the computer you can touch where as virus scanner you can not touch because its software again my point being its software NOT hardware

B. Usability emphasizes utility over aesthetics.
<u>Explanation:</u>
Usability mainly speaks about the utility of an item. There are many wastes created in home and work place and those are sometimes thrown without knowing that it can be re-used for another purpose.
It is always better to re-use the product without considering aesthetic aspects though aesthetic is equally important. We can make the old objects to create a new one.
There are many videos in the social media to make the old objects to be used as a sub-product to create a new object and sometimes it looks better than an old one.
