How many bits are there in a byte?

A byte is eight bits. Each bit can be 0 or 1, so eight bits give 2^8 = 256 possible patterns, which is the range needed to represent a single character in common encodings like ASCII. That’s why the standard size of a byte is eight bits in modern computing. The number 256 reflects how many values a byte can hold, not how many bits it contains; sixteen would imply two bytes, and ten isn’t a standard byte size.
