Understanding Number Bases

Humans naturally count in Base 10 (Decimal). However, computer architecture is built on Base 2 (Binary) consisting of 0s and 1s. To make binary more readable for programmers, Hexadecimal (Base 16) is frequently used in memory addressing and web colors. Octal (Base 8) is often used in Linux file permissions.
