Frequently Asked Questions
What is Hexadecimal (Base-16) and why is it used for text?
Hexadecimal is a base-16 numeral system using sixteen distinct symbols: 0–9 for values 0 to 9 and A–F for values 10 to 15. Because one byte (8 bits) corresponds exactly to two hexadecimal digits (e.g. 11111111 = FF), hex provides a compact, human-readable view of binary computer data.
How is the word 'Hello' represented in Hexadecimal?
The word 'Hello' in hexadecimal is 48 65 6C 6C 6F (48 = 'H', 65 = 'e', 6C = 'l', 6C = 'l', 6F = 'o').
What is the difference between uppercase and lowercase hex?
Hex values are case-insensitive: '4a' and '4A' represent the exact same numeric value (decimal 74 or ASCII character 'J').
