What is the range of possible byte values in computing?

The range of possible byte values in computing is from 0 to 255. This is because a byte consists of 8 bits, and each bit can have a value of either 0 or 1. Therefore, the total number of combinations possible with 8 bits is 2 raised to the power of 8, which equals 256 unique values.

The range starts from 0 and goes up to 255, representing all the possible states that can be represented with 8 bits. This range is commonly used in various applications, such as character encoding in ASCII, where each character corresponds to a specific byte value.

The other choices exceed the maximum representable value of a byte. For example, 0-128 would not cover all possible values of a byte, while 0-512 and 0-1024 far exceed the maximum of 255, which cannot be represented with just a single byte.
