kétállapotos

kétállapotos is a Hungarian term that translates to "bistable" in English. It describes a system or component that can exist in one of two stable states. These states are generally mutually exclusive, meaning the system cannot be in both states simultaneously. Once in a particular state, the system will remain in that state until an external trigger or input causes it to transition to the other stable state.

Examples of kétállapotos systems are found in various fields. In electronics, a bistable multivibrator, often referred to as a flip-flop, is a classic example. It can hold a binary value of either 0 or 1, and it will maintain that value until a clock signal or a set/reset input changes its state. In mechanical systems, a simple light switch is a bistable device, being either on or off. In physics, certain magnetic materials can exhibit bistability, with their magnetization pointing in one of two opposing directions. The concept is fundamental to digital logic and memory storage, where information is represented by these two distinct states. The transition between states is typically caused by a specific input or event, and the system's ability to "remember" its current state is a key characteristic.
