How many bits are there in one byte?

One byte is composed of 8 bits. In computer science, a bit represents the smallest unit of data, which can have a value of either 0 or 1. The byte, made up of 8 bits, serves as a fundamental metric for data measurement in computing, enabling the representation of a range of values, such as characters in a text, by combining combinations of these bits.

The use of 8 bits in a byte allows for the representation of 256 different values, ranging from 0 to 255 in decimal notation. This structure is essential for character encoding schemes like ASCII, where each character corresponds to a specific byte representation.

Understanding that one byte equals 8 bits is crucial for grasping how digital information is stored and processed across various systems and applications.
