How many values can a single byte represent?

A single byte is composed of 8 bits, and each bit can have two possible values (0 or 1). To calculate the number of values a single byte can represent, we multiply the number of possible values for each bit (2) by the number of bits in a byte (8). Therefore, a single byte can represent 2^8, which equals 256 different values. This is because each bit can be in one of its two possible states, and by having 8 such bits, we can have all the possible combinations from 00000000 to 11111111, resulting in 256 unique values.
