第二章——信息的表示和处理 将十进制数n转换为十六进制数: 当x为2的非负整数n次幂时 此时,将n表示为 i+4j 的形式,我们便可以把x写成开头的十六进制数字为1(i = 0)2( i = 1)4( i = 2)8( i = 3),后面跟随 j 个十六进制的0。 i.e. 2048 = 2^11, n = 11 = 3+ 4*2 则十进制的2048用十六进制表示为0X800。 字
第六章——存储器层次结构 磁盘容量 = 字节数(扇区)* 平均扇区数(磁道)* 磁道数 (表面)* 表面数 (盘片)* 盘片数(磁盘) 磁盘结构 内存和磁盘技术的一个基本事实:增加密度(从而降低成本)比降低访问时间容易得多 局部性(locality) 一个有良好局部性的计算机程序倾向于引用邻于其他最近引用过的数据项的数据项,或者最近引用过的数据本身。 时间局限性:被引用过一次的内存位
