Mark scheme
- C Scheduler (1)
- The only correct answer is C. The correct answer is scheduler.
- A is not correct because an interrupt is a signal that needs immediate attention
- B is not correct because a process is a program that is being executed, not a component of the operating system
- D is not correct because a time slice is the amount of CPU time a process is given, not what decides which process runs next
