TranslationsSegmentation
segmentation[‚seg·mən′tā·shən] (communications) The division of a long communications message into smaller messages that can be transmitted intermittently. (computer science) The division of virtual storage into identifiable functional regions, each having enough addresses so that programs or data stored in them will not assign the same addresses more than once. The division of a large computer program into smaller units, called segments. picture segmentation (zoology) metamerism Segmentation in linguistics, the linear division of speech or a text into segments that correlate with specific language units. Segments may be meaningful, as in the case of sentences, words, and morphemes (syntactic and morphological segmentation), or not meaningful, as in the case of syllabemes and phonemes (phonetic segmentation). “Dual linguistic segmentation,” a term introduced by A. Martinet, is also used in this regard. Segmentation is a syntagmatic procedure that precedes definition of paradigmatic units, which are established by comparison of segments. Linguists oppose segmental units to the suprasegmental units of language.
Segmentation (1) In morphology, the division of the body of some animals or of individual organs into a linear series of segments, or metameres. (2) In embryology, a series of consecutive divisions of an egg. segmentation (networking)(Or "segmentation and reassembly", SAR) Breakingan arbitrary size packet into smaller pieces at thetransmitter. This may be necessary because of restrictions inthe communications channel or to reduce latency. The piecesare joined back together in the right order at the receiver("reassembly"). Segmentation may be performed by a routerwhen routing a packet to a network with a smaller maximumpacket size.
The term "segmentation" is used in ATM, in TCP/IP, it iscalled "fragmentation" an is performed at the IP layerbefore the "fragments" are passed to the transport layer.
See for example ATM forum UNI 4.0 specification.
