Answer: Option D
Solution
Answer: Option D
Solution:
It has no value because it's “off”. Therefore, it is a 0 digit. Conversely, if the state is “on”, then it has value. We can represent it as a 1 digit. Binary code, code used in digital computers, based on a binary number system in which there are only two possible states, off and on, usually symbolized by 0 and 1.
