Question

When an IRET instruction isexecuted, what action takes place?

Answer 1

Answer:

IRET(Interrupt return)

This instruction is used in x-86 intel cpu architecture.

The IRET instruction provides for a long return to the program or procedure interrupted. IRET and IRETD these two instructions have the same meaning.

Each interrupt procedure has an IRET instruction stating that the routine ends. The execution of the instruction pops up the IP address from the stack and continues to run the primary program.
