Question

Which of the following are not dependent on the actual hardware performing the physical task?

(a) applications

(b) hardware

(c) registers

(d) parameter block

This question was posed to me in an interview for job.

I need to ask this question from Operating Systems in section Real Time Operating systems of Embedded Systems

Answer 1

Right answer is (d) parameter block

The explanation: The kernel can locate the parameter block by using an address pointer which is stored in the predetermined address register. These parameter blocks are standard throughout the operating system, that is, they are not dependent on the actual hardware performing the physical task.
