The decimal system, or base-10, is the standard numbering system used by humans. It consists of 10 digits (0-9) and represents numbers using powers of 10.
The hexadecimal system, or base-16, uses 16 digits (0-9 and A-F). It is commonly used in computing for concise representation of binary-coded values, allowing a more compact and human-readable format.
The binary system, or base-2, uses only two digits, 0 and 1. It is fundamental in computing and digital electronics, representing data and information using combinations of these two binary digits. Each digit is a binary bit.
