Computers store all characters as binary data, a collection of integers. Binary code is a method of representing computer instructions or information that makes use of the digits 0 and 1 (binary numbers). An assignment of a bit string is made for each instruction or symbol. Instructions, letters, and symbols can all be represented by strings of characters. These codes are utilized in the computing industry for the purpose of encoding data.

This base-2 or binary numeric system is utilized in mathematics and computer science, among other disciplines. With only these two symbols, the system is able to express values. In most instances, the values in binary systems are referred to as binary numbers.

Computers employ the binary system internally when working with digital electronics, especially when working with digital electronic circuits that use logic gates (with values of 0 and 1). Mobile phones, as well as other computer-based gadgets, make use of the binary numbering system as well.

You can convert between binary and the base-10 system, which is the most commonly used by humans. You can also convert between binary and hexadecimal, where four digits of binary represent one digit of hex, and one digit of hex is represented by one binary digit. Another option is to convert back and forth between binary and octal. The binary representation of an octal digit consists of three digits. Binary 000 corresponds to the octal digit 0.
