Types of Primary Storage Devices

Below are some types of primary storage devices.

• Read-Only Memory (ROM) : The ROM holds the instructions that tell the computer how to start up or “Reboot” when you turn on the computer . The information in ROM can not be changed and deleted. It is permanent the ROM is used in the computers as well as the other devices like the smart washing machines.
• Random Access Memory (RAM) : The RAM is the temporary workspace for the computer to store the data while it is running programs and doing the work. Information in the RAM goes away when you turn off the computer. RAM allows you to quickly switch between the different tasks like apps, documents, games and many more things without losing your progress.
• Flash Memory : The Flash memory can store the data for a very long time even when there is no power or charging. It is commonly used in the portable USB drives, cameras, and the mobile devices to store the files and data. The data remains into the flash memory until you delete the data.
• Cache Memory : The cache is a very fast small memory area inside the computers processor (CPU). It holds the data and instructions that are needed frequently so the CPU can access them so quickly. The cache memory is much faster than the RAM because it is close to the CPU.

A primary storage device is where the computer temporarily stores the data that is actively using or working with. It provides quick access to the information the computer needs right now. In this article, we will discuss primary storage device in detail.
