Answer:
255
Explanation:
1 byte has 8 bits, that is, 8 combinations of binary inputs, which can result in calculations up to the number 2 ^ 8-1 = 255 (-1 because 0 will always be the first number), a computer nowadays has 64 bits (8bytes ), thus being able to calculate numbers up to 2 ^ 64-1, an integer file has 4 bytes, being able to calculate up to 2 ^ 32-1, and so on.
