Q. The ____ is the box that houses the most important parts of a computer system?

B

D
System unit
Solution:

The system unit is the box-like case that contains the electronic components of a computer. Many people erroneously refer to this as the CPU. Here you will find devices like the power supply, different drives, the fan, the connectors, and the motherboard. Note that in most cases, the monitor, keyboard, and mouse will not be found inside the system unit layout.

Other names for the system unit include the computer chassis, cabinet, box, tower, enclosure, housing, or simply case.
