​KembaraXtra-Computer Terms – bistable circuit:
A bistable circuit is an electronic circuit that has exactly two stable operating states. The circuit does not change between these states on its own; instead, an external signal or trigger must initiate the transition from one state to the other.
Because it can hold one of two conditions, a bistable circuit is capable of storing a single binary digit, or bit, of information. These circuits are commonly used in memory components, digital logic systems, and devices such as flip-flops that form the foundation of many computing processes.
