Primary storage, also known as main memory, is the internal memory of a computer that is directly accessible by the CPU. It is used to store data and instructions that are currently being processed by the CPU. Secondary storage, on the other hand, refers to external storage devices such as hard drives, solid-state drives, and optical discs, which are used to store data for long-term use. Tertiary storage is a type of storage that is used for archival purposes and is typically slower and less accessible than primary and secondary storage. Examples of tertiary storage include magnetic tape and optical jukeboxes. **
