Answer 1

Explanation:

Stands for "Interrupt Service Routine." An ISR (also called an interrupt handler) is a software process invoked by an interrupt request from a hardware device. ... When the ISR is complete, the process is resumed. A basic example of an ISR is a routine that handles keyboard events, such as pressing or releasing a key.
