The statement below is followed by four options. Each option is related to the item in the statement, but only one is always true. Select the option that always holds and makes the statement true.
"A computer always has ______."
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A processor
The answer must hold for every computer, without exception. An option that is present in most cases but can be missing in even one case is not always true.
Option (1) A printer — a printer is an extra output device; most computers are used without one.
Option (2) A mouse — a laptop can be used with its touchpad and no mouse.
Option (3) A processor — the processor (CPU) is the part that carries out all the work of a computer; there is no computer without one, so this is always true.
Option (4) An internet connection — a computer works offline too, for typing or calculations.
