八、随机存取存储器本文介绍随机存取存储器(RAM)。随机存取存储器是存储目前正在使用的信息的结构。此信息不仅是正在工作的数据,而且包括指导计算机工作的程序。用来存储计算机所使用的信息的技术是很多的。比较熟悉的存储体是磁带、纸带、穿孔卡以及磁盘和磁鼓;所有这些都是基本的、重要的时序存储形式。所存储的信息被组织成较大的字组,连续地存储在字组内,即计算机通过字组1号存储单元,2号存储单元等等。在介绍随机存取存储器前,先介绍一下存储器的结构。计算机中全部的信息是按二进位“1”和“0”来进行存储的。在计算机中,这些位被组成字,一个字刚好是当作实体来看
Eight, random access memory This article describes the random access memory (RAM). Random Access Memory is the structure that stores the information currently in use. This information is not only data that is working, but also programs that guide the work of computers. There are many techniques used to store the information used by computers. The more familiar banks are tapes, tapes, punch cards, and disks and drums; all of these are basic, important forms of timing storage. The stored information is organized into larger blocks that are continuously stored in the block, ie, the block is passed by block 1, block 2, and so on. Before introducing random access memory, first introduce the structure of the memory. All the information in the computer is stored as binary “1” and “0”. In computers, these bits are grouped into words, and a word is taken as an entity
