Question

The fundamental function of a register in digital circuits is to:

• A. Perform Arithmetic operations
• B. Store Binary information
• C. Compare two numbers
• D. Encode input signals

Hint:

Register = memory unit made of flip-flops.

Answer 1

The Correct Option is B

Concept: A register is a group of flip-flops used for storing binary data.

Step 1: Definition of register.
• Collection of flip-flops
• Each flip-flop stores 1 bit

Step 2: Primary function.
• Temporarily store binary data

Step 3: Evaluate options.
• Arithmetic → ALU function
• Storage → Register function ✔
• Comparison → Comparator
• Encoding → Encoder

Step 4: Conclusion. \[ \boxed{(2)\ \text{Store Binary information}} \]
