Base8 corresponds to which number system?

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

Answer: (D)

Base-8 refers to the octal number system. In this system each digit can be 0 through 7, and each place represents a power of eight (8^0, 8^1, 8^2, etc.). The name octal comes from eight, reflecting its eight possible digit symbols. Octal is often connected to binary because three binary bits (from 000 to 111) map directly to a single octal digit, making it a convenient compact way to represent binary values. For reference, binary uses digits 0–1, decimal uses digits 0–9, and hexadecimal uses digits 0–9 plus A–F.
