Binary is the fundamental language of computers. Each digit is called a bit (binary digit). 8 bits make a byte. Used in all digital systems and computer programming.
The decimal system is the standard system for denoting integer and non-integer numbers. It's the most common system used by humans in daily life and commerce.
Octal was used in early computing systems. Today, it's primarily used in Unix file permission systems. Each octal digit represents three binary digits.
Hexadecimal is widely used in computer science and programming. Each hex digit represents four binary digits (a nibble). Commonly used for memory addresses and color codes.
