Show answer & explanation
Correct answer: C
The hexadecimal system is called "Hexa-decimal" because it combines two sets of symbols:
Decimal Digits (0–9): The first ten values are represented by standard numbers.
Letters (A–F): Since we need six more symbols to reach a base of 16, the first six letters of the alphabet are used.
A = 10, B = 11, C = 12, D = 13, E = 14, F = 15.
This system is widely used in computer science for representing memory addresses, color codes (HTML/CSS), and MAC addresses because one hex digit can perfectly represent exactly 4 bits (a nibble).
