Microprocessor
When RET instruction is executed by any subroutine then

without any operation, the calling program would resume from instruction immediately following the call instruction.

the top of the stack will be popped out and assigned to the PC.

the PC will be incremented after the execution of the instruction.

without any operation, the calling program would resume from instruction immediately following the call instruction and also the PC will be incremented after the execution of the instruction.
