Why are Different Number Bases Used?

Decimal (Base 10)

The standard system for humans, using ten digits (0-9). It's the most intuitive for everyday calculations.

Binary (Base 2)

The fundamental language of computers, using only two digits (0 and 1) to represent on/off electrical states.

Hexadecimal (Base 16)

Used by programmers as a more compact and human-friendly way to represent binary data. Common in web design (colors) and memory addressing.

Octal (Base 8)

An older system also used to represent binary data more compactly. It's often seen in file permissions on Linux/macOS systems.
