Why is the process state (i.e., PC, SP, EFLAGS, general
registers) kept in the Kernel
Interrupt Stack before handling an Interrupt? Why could we not
store it in the user memory?
What is the risk?
Homework Answers
Due to following reasons we cannot have the process state (i.e., PC, SP, EFLAGS, general registers) in the user memory:-
- OS cannot trust user processes, as the user processes can be buggy or malicious
- If the user processes crashes it should not affect the OS.
- If there are many processes running at time then there can be full memory utilization in that case the OS should have memory left to run important instructions.
- The OS needs to have fairness to all the user processes, so for that it will need have memory of its own.

Identify a process and state why it is very important to provide and follow the proper steps to carry out the process. What could happen if the process isn't carried out properly? What are some warnings involved in the process? As an example, think about medications and/or antibiotics that all of us have probably used at one time or another, after being diagosed with a cold or illness. When we pick up medicine from the local pharmacy, directions are stapled...
