Terminology: another common name for a bistable multivibrator. Select the widely used digital design term that refers to a bistable.

Introduction / Context:
A bistable multivibrator has two stable states and stores one bit of information. In digital electronics, it is commonly implemented and discussed under a more familiar name. This question checks your vocabulary alignment with standard digital design terminology.

Given Data / Assumptions:

• Two stable output states
• External inputs can set, reset, or toggle the state

Concept / Approach:
The ubiquitous term for a bistable multivibrator in digital systems is "flip-flop". It can be edge- or level-controlled and is the building block of registers, counters, and state machines.

Step-by-Step Reasoning:

Verification / Alternative check:
Textbooks equate the bistable multivibrator with flip-flops (SR, JK, D, T) used in sequential logic.

Why Other Options Are Wrong:

• On-off switch: a mechanical analogy, not a precise circuit type.
• Oscillator: describes astable behavior.
• Latch with analog feedback: imprecise and not a standard term here.
• Schmitt trigger: a comparator with hysteresis, not a memory element.

Common Pitfalls:

• Confusing latches and flip-flops; both are bistables, but "flip-flop" is the canonical term.

Final Answer:
a flip-flop
