Question

Why microprocessor uses the binary number system and not the decimal or any other number system?
​

Answer 1

Answer:

Because there are only two valid Boolean values for representing either a logic “1” or a logic “0”, makes the system of using Binary Numbers ideal for use in digital or electronic circuits and systems.

Answer 2

Answer:

Computers use voltages and since voltages changes often, no specific voltage is set for each number in the decimal system. For this reason, binary is measured as a two-state system i.e. on or off. Also, to keep calculations simple and convert into binary online, computers use the binary number system.
