What is the role of segment register?

Answer Posted / manoj saini

In the x86 processor architecture, memory addresses are
specified in two parts called the segment and the offset.
One usually thinks of the segment as specifying the
beginning of a block of memory allocated by the system and
the offset as an index into it. Segment values are stored
in the segment registers. There are four or more segment
registers: CS contains the segment of the current
instruction (IP is the offset), SS contains the stack
segment (SP is the offset), DS is the segment used by
default for most data operations, ES (and, in more recent
processors, FS and GS) is an extra segment register. Most
memory operations accept a segment override prefix that
allows use of a segment register other than the default
one.
