Based on your expertise, which type of operating system exhibits superior performance: interrupt-driven or non-interrupt-driven?
When a CPU delivers an interrupt, it must stop whatever it is doing to reply to the signal.
I'm curious about the reasons for stopping the procedure in order to complete the assignment.
Let's start with the interrupting process and then go on to the executing process.
explain?
In the context of an operating system, an interrupt is a mechanism that allows the CPU to temporarily halt its current execution and switch to a different task or process in response to an external event. Interrupts are crucial for efficiently managing input/output (I/O) operations. Explain interrupts in I/O operations and provide an example to illustrate the concepts.
