In case of 8-bit numbers. 2^8=256. 2^8/2=128. 128-1=127. so the numbers lie in between -128 to 127. If a number that has value out of this range then it will cause overflow. E.g., if there is an addition of two numbers that fall within the range.

WebIn computer programming, an integer overflow occurs when an arithmetic operation attempts to create a numeric value that is outside of the range that can be represented with a given number of digits – either higher than the maximum or lower than the minimum representable value..
