Question

How do computers hold numbers greater than 255?

Answer 1

Answer:

The total is a number bigger than 8 digits, and when this happens the CPU drops the overflow digit because the computer cannot store it anywhere, and the computer thinks 255 + 1 = 0. Overflow errors happen when the largest number that a register can hold is exceeded. ... Most CPUs use a much bigger word size than 8 bits.
