【填空题】What exactly does an (1)system do? Basically, it performs a number of supporting (2). For example, suppose an application (3) is stored on disk, before the (4) can be executed, it must be copied into main (5) first, because the program that controls a (6)must be in main (7). The process of copying a program from (8)to memory involves considerable logic. The source of a computer’s logic is (9). Thus, if the application program is to be (10), there must be a program in memory to control the loading process. That program is the operating system.
