Word:

Segmentation

Seg`men`ta´tion
n.1.(Biol.) The act or process of dividing into segments; specifically (Biol.), a self-division into segments as a result of growth; cell cleavage; cell multiplication; endogenous cell formation.
Segmentation cavity
(Biol.) the cavity formed by the arrangement of the cells in segmentation or cleavage of the ovum; the cavity of the blastosphere. In the gastrula stage, the segmentation cavity in which the mesoblast is formed lies between the entoblast and ectoblast. See Illust. of Invagination.
Segmentation nucleus
(Biol.) the body formed by fusion of the male and female pronucleus in an impregnated ovum. See the Note under Pronucleus.
Segmentation of the ovum
(Biol.) the process by which the embryos of all the higher plants and animals are derived from the germ cell. In the simplest case, that of small ova destitute of food yolk, the ovum or egg divides into two similar halves or segments (blastomeres), each of these again divides into two, and so on, thus giving rise to a mass of cells (mulberry mass, or morula), all equal and similar, from the growth and development of which the future animal is to be formed. This constitutes regular segmentation. Quite frequently, however, the equality and regularity of cleavage is interfered with by the presence of food yolk, from which results unequal segmentation. See Holoblastic, Meroblastic, Alecithal, Centrolecithal, Ectolecithal, and Ovum.
Segmentation sphere
(Biol.) the blastosphere, or morula. See Morula.
Noun1.segmentation - (embryology) the repeated division of a fertilised ovum
Synonyms: cleavage
2.segmentation - the act of dividing or partitioning; separation by the creation of a boundary that divides or keeps apart
Pronunciation: (SEG-men-TAY-shun)

The process by which muscles in the intestines move food and wastes through the body.

(networking)segmentation - (Or "segmentation and reassembly", SAR) Breaking an arbitrary size packet into smaller pieces at the transmitter. This may be necessary because of restrictions in the communications channel or to reduce latency. The pieces are joined back together in the right order at the receiver ("reassembly"). Segmentation may be performed by a router when routing a packet to a network with a smaller maximum packet size.

The term "segmentation" is used in ATM, in TCP/IP, it is called "fragmentation" an is performed at the IP layer before the "fragments" are passed to the transport layer.

See for example ATM forum UNI 4.0 specification.
