What is INT IN 8086 microprocessor?

In the 8086 microprocessor, INT (interrupt) is an instruction used to trigger an interrupt service routine (ISR). It allows the CPU to temporarily halt its current operations and execute a specific routine to handle events like hardware signals or software exceptions. The INT instruction can take a parameter specifying the interrupt vector, which corresponds to a predefined ISR in the interrupt vector table. This mechanism facilitates multitasking and responsive system behavior by enabling the processor to respond to asynchronous events.
