SEGMENTATION
In a memory management system that is properly a programmer views a program to be collection of program components called as segments. Every segment is a logical unit of a program as defined by the programmer's design. In programming terms a segment generally contains of s set of procedures or data and forms a module of a few software systems.
The motivation for segmentation is to group together data and procedures that possess common attributes for sharing by other procedures.

For the simplicity of execution segments are numbered and are referred to by a segment number.
