What is the purpose? a To reduce hardware costs. b To allow overlapping execution of instructions. c To simplify programming. 38 Which of the following is NOT a benefit of parallel processing? a Increased complexity in programming. b Faster processing times. c Improved resource utilization. 39 In pipelining, what happens if one stage takes longer than expected? a It has no effect on performance. b It can cause a bottleneck. c It speeds up the process. 40 Which is an example of parallel processing? a Running multiple simulations at once. b Executing a single program in steps. c Loading data sequentially. 41 What is an interrupt? a A type of software bug. b A signal that temporarily halts the CPU to process an event. c A constant CPU operation. 42 How does polling work? a The CPU repeatedly checks the status of a device. b It waits for a signal. c It processes data in batches. 43 Which method is more efficient for handling events? a Neither, both are equally efficient. b Polling, for its simplicity. c Interrupts, as they reduce CPU idle time. 44 What is a disadvantage of polling? a It is too fast. b It can waste CPU resources by checking devices constantly. c It requires more hardware. 45 In which scenario is polling preferred? a When the event frequency is low and predictable. b When immediate response is critical. c For high-speed data processing. 46 What happens during an interrupt? a It ignores the event. b It shuts down temporarily. c The CPU saves its current state to handle the event. 47 Which method can lead to latency issues? a Polling, due to its constant checking. b Interrupts, because they are too fast. c Neither, both are instantaneous. 48 What is a common use case for interrupts? a Storing data in memory. b Running background processes. c Handling user inputs like keyboard presses. 49 What is a key advantage of interrupts over polling? a They require less memory. b They are easier to implement. c They allow the CPU to perform other tasks while waiting. 50 Which method is generally more complex to implement? a Polling, because it requires constant checks. b Interrupts, due to the need for managing states. c Neither, both are simple.
