Electrical Engineering XYZ MCQs
A digital circuit that can store on bit is a:
- Gate
- XOR gate
- Register
- Flip-flop
Correct answer: 4. Flip-flop
Explanation: A flip-flop is a fundamental building block of digital circuits used to store binary data. It is a bistable multivibrator, which means it has two stable states and can remain in either state indefinitely until changed by an external input. Flip-flops are used to store a single bit of information (0 or 1) and are commonly used for memory elements in digital systems.
Let’s take a look at other options of this Electrical Engineering XYZ MCQ:
- Gate: A gate is a basic building block of digital circuits that performs a logical operation on one or more binary inputs and produces a single binary output. Examples of gates include AND gate, OR gate, XOR gate, etc. Gates themselves do not have memory capability.
- XOR Gate: An XOR gate (Exclusive OR gate) is a digital logic gate that gives a true (1) output when the number of true inputs is odd. It also doesn’t have memory capability.
- Register: A register is a group of flip-flops (or other types of storage elements) used to store data temporarily in a digital system. Registers can store multiple bits of data and are often used for holding operands, intermediate results, or other data during processing.
