The range of values that can be represented with 8 bits in 2's complement form is:

A. 0 to +128
B. +256 to -256
C. -128 to +128
D. +127 to -128

Answer :

Final answer:

The range of values for an 8-bit number in 2's complement form is from -128 to +127, with the highest positive value being +127 and the maximum negative value being -128 due to one bit being used as the sign bit.

Explanation:

The range of values that can be represented with 8 bits in 2's complement form is -128 to +127. When using 2's complement, an 8-bit number can represent a range of values from -128 to +127, not 0 to +128, +256 to -256, or +127 to -128. This is because one of the bits is used as a sign bit. In 2's complement notation, the highest bit (leftmost bit) is reserved for sign (0 for positive, 1 for negative) and thus, the positive range gets reduced by one.

For an 8-bit value, the maximum positive value is 01111111 (which is +127 in decimal) and the maximum negative value is 10000000 (which is -128 in decimal).
