Which term describes the numbering system with base 2?

• A. Binary Number System
• B. Decimal Number System
• C. Octal Number System
• D. Hexadecimal Number System

Answer: (A)

Base-2 numbering uses only two digits, 0 and 1, and each position represents a power of two. That naming is the Binary Number System. In computing, data is handled as bits—the on/off states that map naturally to two values, making the binary system ideal for digital circuits and storage. The other bases use different sets of digits and bases: decimal uses ten digits (0–9), octal uses eight digits (0–7), and hexadecimal uses sixteen digits (0–9 plus A–F). So base-2 is the binary system.
