While a computer may be viewed as running one gigantic program stored in its main memory, in some systems it is necessary to give the appearance of running several programs simultaneously. This is achieved by multitasking i.e. having the computer switch rapidly between running each program in turn.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): In computer terms, when a computer is switching rapidly between running each program in turn, is called what?
multitasking
