Option 2:
Direct memory access (DMA) principles
Option 3:
Interrupt service routine (ISR) explanation
Option 4:
CPU scheduling techniques

Answer 1

Interrupt-Based Device Interaction allows devices to communicate with the CPU by interrupting the normal flow of execution, utilizing Interrupt Service Routines (ISRs) to handle the interrupts and perform necessary actions.

Step-by-step explanation:

Interrupt-Based Device Interaction is a concept in computer science that allows devices to communicate with the central processing unit (CPU) by interrupting the normal flow of execution. One approach to implement this is through the use of Interrupt Service Routines (ISRs). An ISR is a function that is executed in response to an interrupt signal from a device. It handles the interrupt, performs the necessary actions, and then returns control to the interrupted program. This mechanism allows devices to efficiently interact with the CPU without constantly polling for data or resources.
