二、存储器 存储器是计算机用来保存信息的记忆部件,是计算机各种程序和数据存放与交流的中心。它的基本功能是在控制器的控制下按照指定的位置存入和取出信息。 存储器分为内存储器与外存储器两种,简称内存与外存。用字节(Byte)、千字节(KB)、兆字节(MB)、千兆字节(GB)这些术语来表示存储器的容量。一个字节是一个字母、数字所需的存储空间,一个汉字要用两个字节。1KB等于1024个字节,1MB等于1024KB,1GB等于1024MB。可以这样来直观度量:通常打印的一页文稿含有1000—1500个字
Second, the memory is a computer memory used to save information memory components, is a computer program and data storage and exchange center. Its basic function is to deposit and remove information according to the specified location under the control of the controller. Memory is divided into two kinds of internal memory and external memory, referred to as memory and external memory. Memory usage is expressed in terms of bytes, kilobytes, megabytes, and gigabytes. A byte is a letter, the number of storage space required, a Chinese character to use two bytes. 1 KB equals 1,024 bytes, 1 MB equals 1024 KB, and 1 GB equals 1024 MB. It can be intuitively measured as follows: The usual printed page contains 1000-1500 words
