One byte can be used to encode any integer between '0' and inclusive

Solution (By Examveda Team)

We can count the number of zeros and ones to see how many bits are used to represent 255 in binary i.e. 11111111. Therefore, we have used 8 bits to represent 255 in binary.
1 byte = 8 bits, 2⁸ = 256 ranging from 0 - 255.
