Logical Right Shift operation is equivalent to Group of answer choices Multiplying by 2 Division by 2 Adding 2 Subtracting 2
Added by Jaime G.
Step 1
A logical right shift operation shifts all bits in a binary number to the right by a specified number of positions. The bits that are shifted out on the right are discarded, and zeros are filled in from the left. Show more…

1.) In computers, we call it a "shift left" when data moves leftward in the binary number (i.e. the 1's place goes to the 2's place, the 2's place to the 4's place, and so on). A "shift right" moves rightward in the binary number. Shifts also differ on what the shift-in value is (on a shift left, what goes into the rightmost bit position? On a shift right, what goes into the leftmost bit position?). Computers have three major types of shifts, based on how they fill that position: Logical shift (shift in a 0), Arithmetic shift (compute Val*2 for left shift, val/2 with sign extension for right), and Circular shift (the bit shifted out one side is shifted back in the other side). Develop a single, 4-bit shift register that can implement all of these shifts, as well as a parallel load. Use the following control line settings: C1 C0 Direction Operation 0 0 0 Hold 0 0 1 Load Parallel 0 1 0 Logical right 0 1 1 Logical left 1 0 0 Arithmetic right 1 0 1 Arithmetic left 1 1 0 Circular right 1 1 1 Circular left
