Digital Electronics A computer has a word length of 8 bits (including sign). It is required to determine the range of integers that can be stored in the computer. If 2’s complement is used to represent the numbers, then the range will be -256 to 256 -128 to 128 -128 to 127 -256 to 255 -256 to 256 -128 to 128 -128 to 127 -256 to 255 ANSWER DOWNLOAD EXAMIANS APP
