Question

A shift register is mainly used for

• A. Arithmetic operations
• B. Data storage and transfer
• C. Logic minimization
• D. Counting only

Hint:

Common applications of shift registers: \[ \boxed{ \text{Data storage, data transfer, and serial/parallel conversion.} } \]

Answer 1

The Correct Option is B

Step 1: Recall the purpose of a shift register. A shift register is a group of flip-flops connected to shift binary data from one stage to another.

Step 2: Identify its primary application. Shift registers are mainly used for - storing digital data, - transferring serial and parallel data, - serial-to-parallel and parallel-to-serial conversion. Hence, \[ \boxed{\text{Data storage and transfer}} \] is the correct answer. Therefore, \[ \boxed{(B)} \] is the correct answer.
