Storage

Briefly explain the types of data storage and its relation with the CPU.



There are overall two main types of storage:

- Primary Storage ( memory ): This type of storage is primarily used to store information temporarily. The CPU does not directly access the secondary memory, instead it always relies on the primary memory.

- Secondary storage: This type of storage is primarily used to store data or long periods. This type of memory is stored in external devices such as hard drives etc.

- Any data that resides on a disk or input device cannot be accessed by the CPU directly, it should always reside in the main memory. The control unit accesses the data from the disk memory and places it in the main memory.

- The data is present in the primary memory until the program requiring it is executed or is terminated.
