Detailed explanation-1: -With 8 bits, the maximum number of values is 256 or 0 through 255.

Detailed explanation-2: -One bit of information is so little that usually computer memory is organized into groups of eight bits. Each eight-bit group is called a byte. Because it has 8 bits, it can store or 256 different values.

Detailed explanation-3: -A byte has only 8 bits. A bit is a binary digit. So a byte can hold 2 (binary) ^ 8 numbers ranging from 0 to 2^8-1 = 255. It’s the same as asking why a 3 digit decimal number can represent values 0 through 999, which is answered in the same manner (10^3-1).
