内存和存储之间的区别

什么是记忆?

通过使用寄存器进行存储。它是计算机系统中最重要的组件。从技术上讲,内存称为RAM,代表随机存取内存。

它是计算机系统的组件,允许短期存储数据。在计算机系统中,内存是一个RAM,用于临时存储数据和信息。 RAM包含我们计算机上当前正在运行的所有内容。当用户单击任何应用程序,运行程序或访问文档时,计算机系统会将数据存储在随机存取存储器中。

内存(RAM)也称为易失性内存,因为它在系统关闭时会丢失数据。

内存分为三种类型:

  • 高速缓存存储器
  • 主记忆
  • 二级记忆

什么是存储?

存储是计算机系统中的一个组件,它使系统可以长期存储数据和信息。从技术上讲,它被称为硬盘或SSD(固态驱动器)。

存储在存储器中的数据和信息是永久的。它保存了计算机存储器中未保存的大容量数据。

如果设备电源关闭,则数据在存储设备中仍然可用。因此,它也称为非易失性存储器。

CPU不会直接访问它,因此当应用程序需要数据时,处理器会将数据从存储器传输到内存。它还允许用户无限期访问和存储他们的应用程序,文件和操作系统。

以下是主要的存储类型:

  • HDD(高磁盘驱动器)
  • SD卡
  • CD(光盘)
  • DVD(数字多功能光盘)
  • SDD(固态硬盘)

下表描述了内存和存储之间的区别:

Memory Storage
1. It is usually referred to as Random Access Memory (RAM). 1. It is usually referred to as Solid State Drive (SSD).
2. It is an element which stores the data and information for a short-term basis. 2. It is an element which stores the data and information for a long-term basis.
3. It is a volatile memory. 3. It is a non-volatile memory.
4. It is faster than storage (SSD). 4. It is slower than the memory (RAM).
5. It is a component which accesses the data instantly. 5. It cannot modify or access the data as fast as memory.
6. When the system or device loses power, then the data or information is lost. 6. The data and information will remain even.
7. The modules of this component is expensive than the storage. 7. The cost of the storage device is less than the memory modules.
8. The size of memory devices is not large. 8. The size of storage devices is much larger than memory devices. And, the size goes up to terabytes.
9. This component is made up of registers. 9. This component is made up of magnetic parts or strips.
