Answer: A

Explanation:

Binary is a notational system used to represent an “on” or “off” state in digital devices or systems. Binary uses only two symbols: 0 (off) and 1 (on). Binary is also known as base 2 notation, because each symbol represents a power of 2. Binary is the fundamental building block of all computer operations and data storage, as it can encode any type of information using sequences of bits (binary digits)1112.
