Hi guys, Im starting out with my first question: How do Operating Systems handle Highlevel-Interrupts. I think that's it what people call a "software interrupt" - but that's all I know. I want to get some in-depth knowledge about this. I'll be grateful for any good explanation and links discussing this issue. If there are to made basic separation between Unix-like systems and Windows systems, please specify them (separately). greetings, your deadlock!:happy:
