/seg'ment/ 1. A collection of pages in a
memory management system.
2. A separately relocatable section of an
executable program. Unix executables have a text segment
(executable machine instructions), a data segment
(initialised data) and a bss segment (uninitialised data).
3. network segment.
4. To experience a segmentation fault. Confusingly, the stress
is often put on the first syllable, like the noun "segment",
rather than the second like mainstream verb "segment". This
is because it is actually a noun shorthand that has been
verbed.
5. A block of memory in a segmented address space.

segment (jargon) | segment
/seg'ment/, vi.
To experience a segmentation fault. Confusingly, this is often pronounced
more like the noun ‘segment’ than like mainstream v. segment; this is
because it is actually a noun shorthand that has been verbed.

Segmentation of the ovum, or Egg cleavage (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 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, or Egg cleavage (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.
[1913 Webster]Morula \Mor"u*la\, n.; pl. Morulae. [NL., dim. of L. morum a

development; -- called also mulberry mass, {segmentation
sphere}, and blastosphere. See Segmentation.

(MSS) The maximum amount of TCP data that a

network segment (foldoc) | network segment
A part of an Ethernet or other network, on
which all message traffic is common to all nodes, i.e. it is
broadcast from one node on the segment and received by all
others. This is normally because the segment is a single
continuous conductor, though it may include repeaters(?).
Since all nodes share the physical medium, {collision
detection} or some other protocol is required to determine
whether a message was transmitted without interference from
other nodes. The receiving node inspects the destination
address of a packet to tell if it was (one of) the intended
recipient(s).
Communication between nodes on different segments is via one
or more routers.

reassembly
SAR
segmentation and reassembly
(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.

(1994-12-15)
|
segmented address space (foldoc) | segmented address space
An addressing scheme where all memory
references are formed by adding an offset to a base address
held in a segment register.
The effect is to segment memory into blocks, which may overlap
either partially or completely, depending on the contents of
the segment registers but normally they would be distinct to
give access to the maximum total range of addresses. In this
case the scheme does provide some degree of {memory
protection} within a single process since, for example, a data
reference cannot affect an area of memory containing code.
However, compilers must either generate slower code or code
with artificial limits on the size of data structures.
The best known implementation is that used on the Intel 8086
and later Intel microprocessors, where a 16-bit offset is
added to a 16-bit base address held in one of four segment
base registers. Each instruction has a default segment (code
(CS), data (DS), stack (SS), ? (ES)) which determines which
segment register is used. Special prefix instructions allow
this default to be overridden.
Other computers, such as GE-645/Honeywell Multics,
Burroughs large systems (B-5500, B-6600), and others,
have used segmentation to good effect.
Opposite: flat address space. See also addressing mode.
[In what way were the others better than Intel's {brain
damaged} implementation?].

n.
[Unix]
1. [techspeak] An error in which a running program attempts to access
memory not allocated to it and core dumps with a segmentation violation
error. This is often caused by improper usage of pointers in the source
code, dereferencing a null pointer, or (in C) inadvertently using a
non-pointer variable as a pointer. The classic example is:
int i;
scanf ("%d", i); /* should have used &i */
2. To lose a train of thought or a line of reasoning. Also uttered as an
exclamation at the point of befuddlement.
