How do interrupts improve CPU utilization when multiple applications are running?  By increasing the clock speed of the CPUBy allowing the CPU to remain idle for longer periodsBy enabling the CPU to respond immediately to high-priority tasks, reducing idle timesBy reducing the number of tasks the CPU needs to handle

Interrupts improve CPU utilization when multiple applications are running primarily by enabling the CPU to respond immediately to high-priority tasks, thereby reducing idle times.

Here's a step-by-step explanation:

1. When an application needs the CPU's attention, it sends an interrupt signal. This could be due to various reasons such as needing to perform I/O operations, encountering an error, or completing a task.

2. The CPU, upon receiving the interrupt, stops its current task and saves its state. This allows it to return to this task later.

3. The CPU then services the interrupt by executing the interrupt service routine, which is a special piece of code designed to handle the specific type of interrupt.

4. Once the interrupt has been serviced, the CPU can return to the task it was originally executing, restoring the state it saved earlier.

This process allows the CPU to effectively manage multiple applications by attending to their needs as they arise, rather than having to constantly check on each application. This reduces the amount of time the CPU spends idle, thus improving its utilization.

3. The CPU then services the interrupt by performing the necessary actions requested by the application.

4. Once the interrupt has been serviced, the CPU can return to the task it was originally working on, restoring the state it saved earlier.

5. This process allows the CPU to effectively manage multiple applications, as it can quickly switch between tasks based on priority. This reduces the amount of time the CPU spends idle, thus improving its utilization.

It's important to note that increasing the clock speed of the CPU or reducing the number of tasks it needs to handle are not directly related to the use of interrupts. While these may improve CPU performance, they do not specifically relate to how interrupts improve CPU utilization when multiple applications are running.
