The following Segment Registers are used to protect the Memory of CPU. It is related to Memory layout. such as stack, heap, code and Data of a process.
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.
