The following four requests could come in to an operating system as it is running on a computer system: The clock in the computer has just “ticked,” and we need to update a seconds counter. The program running on processor 2 is trying to perform an illegal operation code. Someone pulled the plug on the power supply, and the system will run out of power in 50 msec. The disk has just read the character that passed under the read/write head, and it wants to store it in memory before the next one arrives. In what order should the operating system handle these requests?
