一、内存的作用 内存在电脑中的作用有点像舞台,各种软件就象轮换登台演出的演员。需要用电脑做什么工作,就要把相应的软件从磁盘上调入内存,内存就是软件运行的地方。和节目规模受舞台大小限制一样,电脑上能够运行的软件大小同样也受到内存大小的限制。例如配置了1MB内存的电脑只能运行DOS及其应用程序,要运行WIN 3.X程序,就必须把内存扩大到4MB以上,而要运行WIN95程序,需8MB内存或更多。一个软件运行完毕后必须从内存中退出,即释放它所占据的内存空间,以便其它软件运行。
First, the role of memory The role of memory in the computer is a bit like a stage, a variety of software is like rotation actors on stage. What you need to do with the computer, it is necessary to transfer the appropriate software from disk to memory, memory is where the software is running. As the program size is limited by the size of the stage, the size of the software that can run on the computer is also limited by the size of the memory. For example, a computer equipped with 1MB of memory can only run DOS and its applications. To run a WIN3X program, you must expand the memory to 4MB or above and 8MB of RAM or more to run the WIN95 program. After a software has been run out of memory, that is, it frees up the memory space it occupies so that other software can run.
