1.	The method of synchronising the processor with the I/O device in which the device sends a signal when it is ready is?(a) Exceptions(b) Signal handling(c) Interrupts(d) DMAThe question was posed to me in an interview for internship.My doubt stems from Accessing I/O Devices topic in section Input/Output Organisation of Computer Architecture
Answer» Correct answer is (C) Interrupts The explanation: This is a method of accessing the I/O devices which gives the COMPLETE power to the devices, enabling them to INTIMATE the processor when they’re ready for TRANSFER.
