question 12 of 20
which comparison would best support the idea presented in this paragraph?

the cpu (central processing unit) is the main part of any
computer system, housing the computers primary
memory, its control unit, and the alu (arithmetic logic
unit), which carries out arithmetic and logic functions. as
the central part of the computer system, the cpu gives
commands to connected devices such as the printer, the
monitor, and the speakers.

a. the cpu is like the computers heart, sending power — but not
information — to the rest of the computer.

b. the cpu is like the general out on a battlefield, calling back to the
home base for instructions.

c. the cpu is like a mechanic, keeping the rest of the computer in
perfect working order.

d. the cpu is like an emperor sitting on a throne, sending orders to
every corner of the realm.

Explanation:

The paragraph emphasizes that the CPU is the central part of the computer system and gives commands to connected devices. Option D compares the CPU to an emperor sending orders (similar to the CPU giving commands), which aligns with the idea in the paragraph. Option A is incorrect as it focuses on power (not commands). Option B has the CPU getting instructions (not giving them). Option C is about maintenance (not command - giving).

Answer:

D. The CPU is like an emperor sitting on a throne, sending orders to every corner of the realm.
