浅谈虚拟内存

statement of virtual memory

内存在计算机的综合指标中占相当重要的位置,内存的大小直接影响计算机性能,也是进一步发展计算机整体性能的瓶颈,故而解决计算机的内存问题就至关重要。虚拟内存是解决内存容量的好方法,它不增加硬件成本,又最大限度地解决了内存小,速度慢的问题。Windows采用交换文件Win386.swp作为虚拟内存。该交换文件可随时调整文件大小,以充分提高硬盘的使用效率。

EMS memory occupies quite important place in computer' s integration index. Capacity of EMS memory affect directly computer performance. It is a bottle-neck to develop computer integer performance. It is important to solve the problem of computer's EMS memory. Virtual memory is a good method to add computer's EMS memory. It does not add hardware coat, and solve the problem that computer's EMS memory is small, and speed is slow. Windows system software uses swap file Win386. Swp as EMS memory. This swap file can adjust file content at any moment to raise hard disk efficiency.
