What is another word for auxiliary storage?
Pronunciation: [ɔːksˈɪli͡əɹɪ stˈɔːɹɪd͡ʒ] (IPA) 
Auxiliary storage, commonly referred to as secondary storage, is a crucial component of a computer system. It provides additional space for the data and programs that cannot be accommodated in the primary memory, i.e, the RAM. There are several synonyms for the term auxiliary storage, including external storage, non-volatile storage, long-term storage, and secondary memory. External storage is a term widely used for devices that are not built into the computer system. Non-volatile storage refers to storage that retains data even if the power is turned off. Long-term storage points to the fact that auxiliary storage is primarily used for data that does not require frequent access. Finally, secondary memory suggests that it comes second in importance after primary memory.
