Imagine a scenario in a server handling multiple requests. How would the system behave if it only used polling for I/O operations? Discuss the potential impact on performance and user experience.
💡 Hint: Think about how a waiter constantly checking every table impacts service.
Design a simple system configuration using interrupts that handles data from three different types of devices: a keyboard, a network card, and a printer. Explain the roles each component would play.
💡 Hint: Envision how each device signals at different times and the CPU's role in responding to these signals.
