1. Match the kind of shift to a description of it or some clue that identifies it:

          logical shift                     no new bits are inserted
          
          
          circular shift                    the sign bit is stuck
          
          
          arithmetic shift                  some bits get lost or destroyed

2. What is another name for circular shift?

3. Which of the following actually does division by 2? Circle all that might apply:

     left logical             left arithmetic            left circular
     
     right logical            right arithmetic           right circular

4. Which of the following actually does multiplication by 2? Circle all that might apply:

     left logical             left arithmetic            left circular
     
     right logical            right arithmetic           right circular

5. Perform all the following shifts on the bit pattern 10100001:

               1-bit left logical          ______________________________
               
               1-bit right logical         ______________________________
               
               1-bit left circular         ______________________________
               
               1-bit right circular        ______________________________
               
               1-bit left arithmetic       ______________________________
               
               1-bit right arithmetic      ______________________________

original                    10100001

1-bit left logical          01000010

1-bit right logical         01010000

1-bit left circular         01000011

1-bit right circular        11010000

1-bit left arithmetic       11000010

1-bit right arithmetic      10010000

6. What would happen to the sign of a negative number if you performed a right logical shift on the number? (The number could be either 2's complement or sign-magnitude.)
