Which term describes the base-2 numbering system using only 0 and 1 digits?

• A. Hexadecimal
• B. Binary
• C. Natural language
• D. Oval (Flowchart)

Answer: (B)

The base-2 numbering system uses only 0 and 1; that naming is binary. In binary, each position is a power of two, with the rightmost digit representing 2^0, the next 2^1, then 2^2, and so on. For example, the binary number 1011 equals 8 + 0 + 2 + 1 = 11 in decimal. This system underpins computing because digital circuits naturally have two states, aligning with 0 and 1. The other options refer to a base-16 system (hexadecimal), human language, or a flowchart shape, not a base-2 numeral system. So the term described is binary.
