A byte is a unit of digital information that commonly consists of eight bits. Bits are the smallest unit of data in computing and digital communications and can represent a value of either 0 or 1. Therefore, a byte can represent 256 different values (from 0 to 255), which is useful for encoding a wide variety of data types, such as characters, numbers, and other forms of information.
