What type of digital logic is also known as a latch?
- AA decade counter
- BAn OR gate
- CAn op-amp
- DA flip-flop
Correct answer: D — A flip-flop. From the official ISED question bank, verified word for word.
Why
A flip-flop is the correct answer because it is a digital circuit designed to store one bit of information by holding its output state until a specific signal changes it, which is exactly what a latch does. The full explanation — and one for every question — is in Pro.
