<P> In computing , multitasking is a concept of performing multiple tasks ( also known as processes ) over a certain period of time by executing them concurrently . New tasks start and interrupt already started ones before they have reached completion , instead of executing the tasks sequentially so each started task needs to reach its end before a new one is started . As a result , a computer executes segments of multiple tasks in an interleaved manner , while the tasks share common processing resources such as central processing units ( CPUs ) and main memory . </P>
