1. At Papaye fast-food joint, on entry, customers take a number to be served. The salespersons press buttons to increment numbers on the wall as they attend to each customer. Assuming on entry, you picked number 40. Counter 1 is serving customer #38 and counter 2 is serving customer #39. The sign on the wall says, “Now Serving #39” and you’re ready with your order. Counter 2 finishes with customer #39 and presses the button so the sign says, “Now Serving #40.” But just then the clerk at counter 2 is called to the telephone and leaves the counter, never to return (an interrupt). Meanwhile, counter 1 presses the button and proceeds to serve #41 — and you’ve missed your turn. Counter 1 continues to serve #42, #43, and so on, thinking that counter 2 has attended to you. a. In the computer system, what is the term given to this scenario? b. In a computer system, explain any three (3) mechanisms that can prevent this situation from happening.
