Please help

1. Explain how Interrupt increases processor efficiency, whereas
today's computer already has a high clock speed and large memory?

2. Some examples of LINUX Operating Systems, no driver hardware is required. Please explain, what happens if the kernel does not recognize a piece of hardware installed?

3. In the service provided by the Operating System, explain what is meant by the statement “controlled access to files” and give an example.

4. A process execution can be interrupted by "Interrupt" or "Traps".
Explain the difference between Interrupt and Trap and give examples for Interrupt and Trap.

5. Please explain how the fork() system call can create new processes
which can run in parallel. Give an example of a program using system
