WebMay 7, 2024 · As a result of external interrupts, the operating system's state changes. As a result of these changes, the operating system, upon returning from interrupt, may choose to resume a different thread than the one interrupted (in another process even), leaving the interrupted thread in a suspended state for later resumption. WebInterrupts are the events that temporarily suspend the main program, pass the control to the external sources and execute their task.

WebHardware Interrupts Hardware interrupt is caused by any peripheral device by sending a signal through a specified pin to the microprocessor. The 8086 has two hardware interrupt pins, i.e. NMI and INTR. NMI is a non-maskable interrupt and INTR is a maskable interrupt having lower priority. One more interrupt pin associated is INTA called WebInterrupts could be classified based on the source of the interrupt signal, and also based on the way it’s implemented in memory. Interrupt signals could be generated by hardware or software. Interrupts could be implemented in memory as vectored or non-vectored interrupts. So, let’s classify interrupts in more detail.
