多年来,大量的学校,企业,工厂,家庭,个人电脑,笔记本,电子数码产品,回收价格,快速上门回收。
现代随机存取存储器依靠电容器来存储数据。因为电容或多或少会漏电,如果不做特殊处理,随着时间的推移,数据会逐渐丢失。刷新就是读取电容的状态,然后按照原来的状态给电容充电,弥补失去的电荷。刷新的需要正好解释了随机存取存储器的易失性。
random access
The so-called "random access" means that when the data in the memory is read or written, the time required has nothing to do with the location where the information is located or the location where it is written. On the contrary, when reading or writing information in a Sequential Access storage device, the time required is related to the location. It is mainly used to store the operating system, various applications, data and so on.
When the RAM is in normal operation, data can be read from or written into the RAM. Compared with ROM, RAM has the advantages of convenient reading/writing and flexible use, which is especially suitable for frequent and rapid data replacement.
波动性
当电源关闭时,RAM无法保存数据。如果需要保存数据,必须将数据写入长期存储设备(如硬盘)。
RAM的工作特点是上电后可以随时访问任意位置单元的数据和信息,断电后内部信息消失。
在计算机中,RAM和ROM都是数据存储器。RAM是一种随机存取存储器,它的特点是易失性,即掉电和失忆。
ROM通常是指固化的内存(一次写入,多次读取),其特性与RAM相反。比如文件因突然断电或未保存而关闭,ROM可以随机保存之前未保存的文件,但RAM会让之前未保存的文件消失。
