hardware mechanisms

The operating system requires hardware support to fulfil some of its functions. Can you give me three examples of hardware mechanisms, which can be provided in a modern computer system to support operating system.

================== my attempt was as below:======================= Hardaware security, hardware protection, hardware access mechanisms.

Am I right?

Even though 3 things is not enough you can build a "mini-OS" with these 3 things;

  • CPU Scheduling
  • Dynamic Memory Allocation
  • Interrupts

Given how the question is phrased, I have a feeling this is a homework question that is being crowd-sourced.... ok, here goes...

virtual memory addressing
addressing of i/o devices
privileged instructions (ala ring0)
