Segmentation errors appear in NS2 because pointers in the source code sometimes cause errors. If you encounter one of these errors first cut your off and back on again. Many times this will make the error go away. If it does not you may need to contact the makes of NS2 for advice.
The pattern of repeated segmentation is called segmentation fault or segfault. This occurs when a program tries to access a memory segment that it doesn't have permission to access, leading to a segmentation violation error.
pls tel me the scope of ns2
you don't need to use ns2 programming
Linear
The compound name for NS2 is disulfur mononitride.
ns1 or ns2
Unfortunately, the problem is usually caused by the application itself. You should file a bug report with the application's developers if it reoccurs.
In groups 13 through 18, valence electrons may be in the s, p, and d sublevels. Group 13 elements have valence electrons in the s and p sublevels, while group 14-18 elements may also have valence electrons in the d sublevel in addition to s and p sublevels.
In the case of C, execution halts with a segmentation fault because the literal address of NULL is never allocated to a running program.
Currently NS2 development by VINT group is supported through Defense Advanced Research Projects Agency (DARPA) with SAMAN and through NSF with CONSER, both in collaboration with other researchers including ACIRI (see Resources). NS2 is available on several platforms such as FreeBSD, Linux, SunOS and Solaris. NS2 also builds and runs under Windows.
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.
segmentation is a creative prcess. marketers normally segment markets by combining several segmentation variables rather than relaying on a single segmentation base. THERE ARE 4 METHODS OF HYBRID SEGMENTATION * Value and Life Style (VALS) * psychographic-demographic segmentation * geo-demographic segmentation * yankelovich's mind base segmentation
