Flip-Flop

A flip-flop is a fundamental digital circuit that can store one bit of binary information (0 or 1) and maintain that state until deliberately changed by input signals. It acts as the basic building block for computer memory, registers, and sequential logic circuits. Common types include SR (Set-Reset), D (Data), JK, and T (Toggle) flip-flops, each with different input configurations and triggering methods. They are essential components in digital systems for storing data, counting, and creating memory elements.
