Which characters are used in the hex system for numbers?

• A. Letters A through F
• B. Arabic numbers from 0 to 9 only
• C. Arabic numbers and letters A through F
• D. Roman numerals

Answer: (C)

The hex system, or hexadecimal system, is a base-16 numbering system that utilizes both the ten digits of the decimal system (0 through 9) and the first six letters of the alphabet (A through F) to represent values. In hexadecimal, the letters A through F correspond to the decimal values 10 through 15. Thus, the full range of characters used in this system includes Arab numerals (0 to 9) and the letters A through F. This combination allows for the representation of values that are one digit higher than in the decimal system, effectively doubling the number of distinct symbols used in counting. The use of both Arabic numerals and letters is essential for the proper functioning of hexadecimal notation, especially in fields such as computing and digital electronics, where efficient data representation is critical.
