Explain the function and mechanism of interrupts, including how they are generated and processed through an interrupt service routine, as well as the consequences of interrupts. Software interrupts can occur from events like division by zero or simultaneous memory access by two processes, while hardware interrupts can be triggered by actions such as key presses or mouse movements.

Quick explanation

Explain the function and mechanism of interrupts, including how they are generated and processed through an interrupt service routine, as well as the consequences of interrupts. Software interrupts can occur from events like division by zero or simultaneous memory access by two processes, while hardware interrupts can be triggered by actions such as key presses or mouse movements

• This point belongs to Types of software and interrupts, especially Types of software and interrupts outcomes.
• You need to be able to explain the function and mechanism of interrupts, including how they are generated and processed through an interrupt service routine, as well as the consequences of interrupts. Software interrupts can occur from events like division by zero or simultaneous memory access by two processes, while hardware interrupts can be triggered by actions such as key presses or mouse movements.
• The key ideas to know are Describe, Explain, and Outline.
• Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
