How many bits are there in one byte?

One byte is composed of 8 bits. This is a fundamental concept in computer science and digital electronics. A bit, which stands for binary digit, is the smallest unit of data in computing and can represent either a 0 or a 1. When grouped together, 8 bits form a byte, which is the standard unit for measuring data in computer systems. This grouping allows for the representation of 256 different values (2^8), commonly used in various applications such as character encoding in ASCII. Understanding that a byte is made up of 8 bits is crucial as it forms the basis of how data is stored, processed, and transmitted in all digital devices.
