Interrupts really help computer systems at universities work better when it comes to handling input and output (I/O). Here’s how they do it:
Asynchronous Processing: Interrupts let the CPU, which is the brain of the computer, manage I/O tasks without having to constantly check on them. This checking process, called polling, can waste a lot of time. In fact, polling can use up to 50% of CPU time, while interrupts keep that waste down to less than 5%.
Event-Driven Execution: When an I/O device, like a printer or a mouse, finishes its job, it sends a signal called an interrupt. This tells the CPU to jump in and take action right away. Because of this, the time it takes for the CPU to respond drops from a longer wait in polling to just a quick moment in interrupts.
Resource Utilization: Research shows that systems using interrupts can handle up to 95% of I/O requests really efficiently. This means they work faster and are much more responsive compared to systems that rely on polling.
In summary, interrupts make computer systems at universities quicker and more effective at dealing with tasks.
