What are the two main types of storage devices?

The two main types of storage devices are classified as primary storage and secondary storage.

Primary storage refers to the main memory of a computer, which is typically volatile and used for immediate data access by the CPU. This includes components like RAM (Random Access Memory) where data is stored temporarily during active processes.

Secondary storage, on the other hand, is used for long-term data storage. This type of storage is non-volatile and retains information even when the computer is turned off. Examples of secondary storage include hard drives, solid-state drives, CDs, and USB flash drives.

Understanding the distinction between these two types of storage is essential for comprehending how data is managed in computing systems. Primary storage is crucial for active tasks and speed, while secondary storage is important for data retention and capacity.
