Frequently Asked Questions

Why do computers use Binary?

Computers use binary (Base 2) because their hardware is composed of millions of tiny switches (transistors) that can only have two states: ON (1) and OFF (0).

Why do programmers use Hexadecimal?

Hexadecimal (Base 16) is used because it provides a much shorter, human-readable representation of long binary strings. One hex digit perfectly represents four binary digits (a nibble).
