Fundamental function of register in digital circuit is to:
Choose the correct answer:
A.
perform arithmetic operation
B.
store binary information
(Correct Answer)
C.
compared two number
D.
encode input signal
Correct Answer:
store binary information
Explanation
Solution
In digital electronics, a register is a group of flip-flops. Its primary purpose is explained through the following technical points:
Storage Element: A single flip-flop is a 1-bit storage cell. When we group n flip-flops together, we create an n-bit register capable of holding n bits of binary data.
Data Retention: Registers are used within the CPU (Central Processing Unit) to hold data temporarily so that it can be accessed quickly by the ALU (Arithmetic Logic Unit).
Binary Information: The fundamental function is to store binary information (0s and 1s) until it is needed for processing or transferred to another part of the system.
Comparison of options:
Option (a): Arithmetic operations are performed by the ALU.
Option (c): Comparing numbers is done by a Comparator.
Option (d): Encoding signals is done by an Encoder.
Conclusion
The fundamental function of a register is to store binary information.
The correct option is (b).
