Binary data is information represented using only two symbols: 0 and 1. In computing, these correspond to electrical states (off/on, low/high voltage) in hardware. Every type of digital data—text, images, audio, programs—is ultimately stored and processed as sequences of binary digits Bits. A group of 8 Bits forms a Byte, the basic unit of data in most computer systems.
