查询词典 compact disc read only memory

This happens because if free memory falls below a minimum value, the host operating system continually frees up memory by swapping to disk to maintain that amount of free memory.

这种情况是因为空余的内存降低到了一个最小的数值，这时主机要不断地使用磁盘交换数据来释放内存。

Protected mode allows for 16M of memory but is also capable of protecting the operating system and programs from accident and deliberate destruction by users, a feature that is absent in the single-user 8088/8086 Virtual memory is a way of fooling the microprocessor into thinking that it has access to an almost unlimited amount of memory by swapping data between disk storage and RAM.

在保护模式下系统可用16M的内存寻址并且可防止操作系统或程序被用户不经意或故意破坏。这个特征是单用户8088/8086所不具备的。所谓虚拟内存就是通过在磁盘存储器与RAM中交换数据将微处理器骗过，使之认为它有无限大的内存寻址空间。
