HOPE IT IS HELPING FOR U GUYS.... THANK UUUUU

Answer 2

The correct answer is option C. Interrupt driven I/O

• Interrupt-driven I/O is a different type of I/O system. Interrupt I/O is a method of controlling input/output activity in which a peripheral or terminal that requires data transmission delivers a signal.
• A program interrupt will be created as a result of this.
• At the time determined by the I/O interrupt's priority level.
• Processors engage an interrupt service routine about the whole interrupt system.
• The routine's functionality will be determined by the processor's interrupt level and priority system.
