srs

SRS is a commonly used acronym with several distinct meanings across different fields.

In software engineering, SRS stands for Software Requirements Specification. It is a structured document describing the intended functionality, performance, interfaces, and constraints of a system. The SRS serves as a contract among stakeholders and developers and provides a basis for design, testing, and validation.

In automotive safety, SRS refers to the Supplemental Restraint System, which includes airbags, seat belt pretensioners, and related sensors. The SRS is designed to deploy to reduce injury in crashes. It relies on diagnostics, maintenance, and proper installation and may be indicated by a warning light.

In statistics, SRS denotes a Simple Random Sample, a sampling method in which every member of a population has an equal probability of selection. Sampling is typically done without replacement, using random numbers or generators. SRS supports unbiased estimates and straightforward analysis.

In geography and geospatial data, SRS can mean Spatial Reference System, a framework that defines coordinate systems, datums, projections, and units for maps and measurements. An SRS is identified by a code, such as an EPSG code, and ensures consistent location data.

In medicine, SRS stands for stereotactic radiosurgery, a non-invasive technique that concentrates high-dose radiation on a precise target, such as a brain lesion, while sparing surrounding tissue. It is typically delivered in one or few sessions using image guidance.

Other meanings exist in fields such as education and information technology; the intended sense is usually evident from context.
