Answer:
twos complement value is (-2^15 -1) -32768 to 32767.
excess notation value is -32768 to 32767.
unsigned binary value is (2^16) 0 to 65535
Explanation:
Excess notation: used to represent signed integers. Always uses fixed number of bits with leftmost representing the sign.
Twos complement notation: As opposed to excess notation, a sign bit of 0 is used to represent the non-negative (+) sign and a 1 for the negative (-); again, zero is included in the non-negative set.
Unsigned Binary values: are binary values/bits that don't have signs
