Häiriönsiedettävä

Häiriönsiedettävä is a Finnish term that translates to "disturbance-tolerant" or "fault-tolerant" in English. It is primarily used in the context of engineering and technology to describe systems or components that can continue to operate, even when subjected to disruptive external influences or internal malfunctions.

A häiriönsiedettävä system is designed with redundancy, self-healing mechanisms, or other resilience strategies. This allows it to maintain its functionality or at least a degraded but still usable state when faced with errors, unexpected inputs, or failures in parts of its architecture. For example, in computing, a häiriönsiedettävä operating system can recover from a crash of one of its processes without bringing the entire system down. In telecommunications, häiriönsiedettävä networks can reroute data if a link fails.

The concept is crucial for ensuring reliability and availability in critical applications where downtime or failure can have significant consequences. This includes areas like power grids, air traffic control, financial systems, and industrial automation. The goal of designing for häiriönsiedettävyys is to minimize the impact of failures and disruptions, thereby increasing the overall robustness and trustworthiness of the system. It is an important consideration in the design and development lifecycle of many technological solutions.
