Did you ever try to use a computer with only mouse and monitor?
Hi;
In the question, Robert gives the explanation that there is an error in the BIOS. A BIOS (Standing for Basic Input & Output System) is a ROM chip, and is vital for the computer to initialize devices such as RAM, the CPU, etc. If there is ever an error there, a computer simply cannot boot.
From the options given, your answer given would be C. ROM.
I hope this helps!
Most computer devices are connected to the computer through port
