Which base is described as using digits 0-9 and letters A-F for representation?

• A. Base 16
• B. Base 10
• C. Base 3
• D. Binary Numbering System

Answer: (A)

Understanding numeral systems: hexadecimal uses digits 0-9 and letters A-F to represent values. In this base, each symbol stands for 0 through 15, with 0–9 covering the values 0–9 and A–F covering 10–15. This compact form is handy in computing because one hex digit corresponds to four binary bits, making it easy to map between binary and a readable representation. So, the base described as using digits 0-9 and letters A-F is hexadecimal, or base 16. The other bases use different sets of digits: base 10 uses only 0–9, base 3 uses 0–2, and binary uses only 0 and 1.
