visszagörgethetség

Visszagörgethetőség, a term derived from Hungarian, refers to the property of a system or process to be reversible, meaning that its state can be returned to a previous condition or original configuration. This concept is particularly relevant in fields such as physics, computer science, and engineering. In physics, reversibility is often associated with thermodynamic processes that can be undone without leaving any net change in the system or its surroundings. This ideal scenario is contrasted with irreversible processes, which are more common in the real world and involve some form of energy dissipation or entropy increase.

In computer science, visszagörgethetőség relates to the ability to undo operations or revert a system to a previous state. This is a fundamental principle behind features like "undo" functionality in software applications, transaction management in databases, and checkpointing in distributed systems. A system with high visszagörgethetőség allows users or administrators to recover from errors, experiment with changes safely, or retrace steps in a complex workflow.

The degree of visszagörgethetőség can vary greatly depending on the system's design. Some systems are designed to be fully reversible, while others may only offer partial reversibility or no reversibility at all. The implementation of visszagörgethetőség often involves mechanisms for storing historical states or logs of changes, which can incur computational overhead and memory usage. Nevertheless, the benefits of being able to revert to a known good state often outweigh these costs, making it a desirable characteristic in many applications.
