Definition of computer storage devices:

The storage device is a hardware device that is used to store data and information. They Provide one of the core functions of the modern computer. They come in different sizes and shapes depending on the needs and functionalities.

 

 

 

 

Types of storage:

Primary storage

A primary storage device is any storage device or component that can store nonvolatile data in computers, servers, and other computing devices. It is used to hold/store data and applications temporarily or for a shorter period of time while the computer is running.

RAM

This is called Random Access Memory because any of the data in RAM can be accessed just as fast as any of the other data. This is generally located on the motherboard of the computer.

 Secondary storage

Secondary memory is not directly accessible by the CPU. The computer usually uses its input/output channels to access secondary storage and transfers the desired data using an intermediate area in primary storage.

Hard disk is an example for secondary storage.
