Fail-fast
Fail-fast is a software design principle under which a system reports or terminates immediately when it detects an invalid condition, rather than continuing in a corrupted state.
Fail-safe
Fail-safe, also called a fail-safe device, describes a design in which a failure places a system in its safest state rather than creating a hazard.
Failover
Failover is the automatic switch of operation from a failed primary component to a redundant standby one, so a service keeps running without human intervention; the same switch done by an operator is called switchover.
Failure in time
Failure in time (FIT) is a unit of failure rate in electronics reliability engineering, defined as one failure per billion device-hours and codified in the JEDEC standard JESD85.
Failure mode, effects, and criticality analysis
Failure mode, effects, and criticality analysis (FMECA) is a bottom-up reliability method, extending FMEA, that identifies failure modes and ranks them by severity and occurrence.
Fair clustering
Fair clustering is a family of machine learning algorithms that partition data into clusters while satisfying fairness constraints, such as approximate demographic balance between protected groups.
FAIR data principles
FAIR data principles: Findable, Accessible, Interoperable, Reusable; guidelines from FORCE11's Wilkinson et al. 2016 Scientific Data paper making research data and metadata machine-actionable for reuse, distinct from open data and complemented by CARE principles.
Fair Friend Group
Fair Friend Group (FFG; 友嘉集团) is a Taiwan-based industrial conglomerate founded in 1979, operating machine tool, industrial equipment, and green energy divisions across 94 companies.
FAIR principles
The FAIR principles are fifteen guidelines for data management, published in 2016, stating that scholarly data should be Findable, Accessible, Interoperable, and Reusable for machines and people.
