1. What range of values can be stored in an 8-bit register, assuming the value is encoded with: a) an unsigned binary code. b) a 2's complement binary code. 2. What is -5 and +5 in 4-bit two's complement. Repeat for 5-bit, 6-bit, 7-bit and 8-bit 2's complement. What pattern do you notice? 3. A 32-bit computer register holds the value FFFFFFF9. What number is being represented if value is encoded using two's complement? Please show work and explain
