What happens to bits when a logical binary shift is performed on a positive 8-bit binary integer?

• Bits are shifted from the end of the register and zeros are shifted in at the opposite end.

• Bits are shifted from the end of the register and ones are shifted in at the opposite end.

• Bits remain unchanged and zeros are added to the end.

• Bits are shifted from the end of the register and random bits are shifted in at the opposite end.

What is the effect of using two's complement on an 8-bit binary integer?

• It converts a positive binary integer to a negative one and vice versa.
