Agreed! Interrupts allow multiple devices to signal the CPU without waiting.

I think they need to issue interrupts. It’s the best way to get CPU attention.

Yep, the CPU handles them based on priority levels!

Isn't there a priority system for those interrupts?

Wait, can they all interrupt at the same time?

Interrupt request is the obvious choice. The CPU can't ignore that, right?

Interrupt request is the way to go. Gotta cut in line and demand that CPU time!

Interrupt request, of course! That's the only way to get the CPU's attention.

I feel like the answer is related to DMA, but I'm confused about whether that's the best option for simultaneous communication.

This reminds me of a practice question where devices had to share the bus. I think they might need to send a signal to indicate they want to communicate.

I remember something about priority levels for interrupts, but I can't recall if all devices can interrupt at the same time or if they have to wait their turn.

I think each device needs to issue an interrupt request to the CPU, but I'm not entirely sure how that works with multiple devices.

I've got a strategy in mind. I'll start by listing out the key communication methods, then analyze how each one would work for multiple simultaneous devices.

This question is testing our understanding of CPU interfacing. I'll need to carefully evaluate the requirements and match them to the available communication options.

I'm a bit confused on this one. I'll need to review my notes on CPU communication protocols to figure out the optimal solution.

Okay, I think I know the right approach here. I'll need to consider the pros and cons of each communication option to determine the best fit.

Hmm, this seems like a tricky one. I'll need to think through the different communication options and how they might work for multiple devices.
