Interrupt Controller

An Interrupt Controller is a component in a computer system that manages how the processor responds to various events or signals called "interrupts." These interrupts can come from hardware devices like keyboards, disks, or network cards, indicating they need attention. The controller prioritizes these signals, ensuring the processor addresses the most important tasks first without being overwhelmed. It helps coordinate multiple simultaneous requests efficiently, maintaining smooth system operation. Essentially, it acts as a traffic controller, directing the flow of information so the computer can respond quickly and correctly to different device needs.
