Knowledge of binary number system is required for the designers of computers and other digital systems because
Answer: D
The reason is that the devices used in these systems operate in binary.
Digital circuits are built from switching elements, transistors, gates and flip-flops, that are reliably in one of two states, on or off, high or low. Every number, character and instruction a computer handles is therefore stored and processed as patterns of 0s and 1s, and a designer must work in that system.
Ease of learning binary, Boolean algebra or binary codes is not the reason. Binary is used because the hardware has two states, whatever its difficulty.
