Question

Early electronic computing devices were:

inexpensive.
compact and lightweight.
efficient in operation.
manpower intensive.

Answer 1

Option D is the correct answer.

Step-by-step explanation:

Early electronic computing devices were manpower intensive.

While going through the history of computer and computing devices we come to know that in earlier times computer machinery used to so massive that a computer sometime take a space of full room.

So in order to control and operate such a big device much labor was needed and a lot of power too. Computing devices at that time were not inexpensive because technology was just arising so a lot of power was consumed.

Moreover, in contrast to these days, machinery was less efficient at that older time obviously.
