Question

why do computers use zeros and ones?
a because binary numbers are simplest.
b because binary numbers are the bases upon which all other number systems are built.
c because digital devices have two stable states and it is natural to use one state for 0 and the other for 1.
d because combinations of zeros and ones can represent any numbers and characters.

Explanation:

Computers use electronic circuits. Digital devices have two stable states (e.g., on/off, high/low voltage). It is natural to map these two states to 0 and 1 (binary digits). Binary is the fundamental language for computer hardware operations.

• Option A: Binary isn't just about simplicity in number - system form. The key is hardware compatibility.
• Option B: While other number systems can be built from binary, this is more of a consequence, not the root reason for computer use.
• Option D: The ability to represent numbers and characters is an application, not the core reason related to computer hardware design.

Answer:

C. Because digital devices have two stable states and it is natural to use one state for 0 and the other for 1.
