| Question 37 |
A multi-user, multi-processing operating system cannot be implemented on hardware that does not support
| Address translation | |
| DMA for disk transfer | |
| At least two modes of CPU execution (privileged and non-privileged) | |
| Demand paging | |
| Both A and C |
Question 37 Explanation:
Address translation and atleast two modes of CPU execution (Privileged and non-privileged) are needed to implement multiuser and multiprocessing operating system, because address translation provides memory protection which ensures that a given process does not interfere with another, and we need privileged and non-privileged instruction, so that user and OS interconnects properly.
