Segmentation

Typically, the logical address space of a process is composed of different type of segments:
code – one segment per code module.
static variables – one segment per module containing static variables.
heap memory – one segment.
shared memory – one segment per shared region.
stack – one segment.
Different segments may have different sizes.
In a segmentation architecture, the segments of a process are manipulated separately.
Dynamic partitioning may be used to allocate each segment.
As a consequence, a process may not be contiguous in memory.
Even, some segments may not be in main memory.
