  • 第2题：

    下列存取速度最快的是(31)。

    A．Flash存储器

    B．DRAM存储器

    C．高速缓存(CACHE)

    D．磁盘


    正确答案：C
    解析：计算机系统的存储器被组织成一个金字塔形的层次结构。在这个层次结构中，自上而下，依次为CPU内部寄存器、芯片内部的高速缓存(CACHE)、芯片外的高速缓存(SRAM、DRAM、DDRAM)、主存储器(Flash、PROM、EPROM、EEPROM)、外部存储器(磁盘、光盘、CF卡、SD卡)和远程二级存储(分布式文件系统、Web服务器)这六个层次的结构。这些设备从上而下，依次变得速度更慢、访问频率更小、容量更大，并且每字节的造价也更加便宜。
