Frequently Asked Questions
What are the common number bases used in Computer Science?
The 4 primary number bases are: Binary (Base 2: 0, 1), Octal (Base 8: 0–7), Decimal (Base 10: 0–9), and Hexadecimal (Base 16: 0–9 and A–F).
Why is Hexadecimal used instead of Binary?
Hexadecimal is a compact human-friendly shorthand for binary. Exactly 4 binary bits (one nibble) map cleanly to 1 hexadecimal digit (e.g., 1111 1111 in binary = FF in hex).
What is Two's Complement?
Two's complement is the standard binary method computers use to represent signed negative integers. To find the two's complement of a binary number, invert all bits (0 to 1, 1 to 0) and add 1.
