一、计算机中存储体系是一个金字塔 存储器是计算机中不可缺少的部分。从体系结构上看可分为内存储器和外存储器。内存储器是直接与CPU连接,要求它在存取速度上与CPU相匹配,通常用半导体存储器芯片组成,由于成本高,容量通常不太大。大量的数据通常是保存在外存储器内。外存储器又可以分成几个层次。与内存储器相连接的是联机
First, the computer storage system is a pyramid memory is an indispensable part of the computer. From the architectural point of view can be divided into internal memory and external memory. The internal memory is connected directly to the CPU, requiring it to match the CPU speed of access, usually with a semiconductor memory chip, which is usually not large due to the high cost. Large amounts of data are usually stored in external memory. External memory can be divided into several levels. Connected to the internal memory is online
