seg

Seg is an acronym or abbreviation that appears in several different domains, with meanings that depend on context. It is often used as shorthand for segmentation or segment, but has more specific senses in various fields.

In computing and information technology, seg commonly denotes a segment, a contiguous portion of memory or data. In x86 architecture, memory is organized into segments managed by segment registers, affecting addressing, protection, and data locality. Segments are also used in data streaming and media processing to divide content into units for processing or transport, such as fixed-length segments in streaming protocols.

In geophysics, SEG typically refers to the Society of Exploration Geophysicists, a professional organization known for publishing standards and conventions. A prominent example is the SEG-Y seismic data format, which standardizes the storage of seismic traces and related information used in subsurface imaging.

In linguistics and phonetics, a segment is a basic unit of sound, such as a phoneme or phone. Segmentation tasks involve dividing continuous speech into these discrete speech segments for analysis or recognition.

In other contexts, SEG can denote socio-economic group classifications used by marketers or researchers in some regions, or function as an acronym within organization names or technical standards. The uppercase form SEG often signals an organization, standard, or file format, while seg in lowercase serves as a general shorthand for segmentation or segments.
