The binary system, or base-2 numeral system, uses only two digits: 0 and 1. It is fundamental to computer operations because digital electronics rely on two states (low and high voltage) to represent these digits. In computers, binary numbers are used to perform all computations, data storage, and processing. Each binary digit (bit) represents a power of 2, and combinations of bits can represent any data or instruction, enabling the complex functions and calculations performed by modern computers.
