What is data storage?

Data storage is the temporary file generated by data stream in processing or the information need to be found in processing. Recording data with some formats in the computer internal or external storage media. Data storage should have a special name which could reflect the characteristics of information. Data stream reflects the flowing data in system, it shows the characteristics of dynamic data; data storage reflects the static data in system, it shows the characteristics of static data.

Computer data storage provides one of the core functions of the modern computer, that of information retention. The organizational form of data storage is due to storage medium. In contemporary usage, memory usually refers to a form of semiconductor storage known as random access memory (RAM) and sometimes other forms of fast but temporary storage. Similarly, storage today more commonly refers to mass storage - optical discs, forms of magnetic storage like hard disks, and other types slower than RAM, but of a more permanent nature.

Memory type of data and organizations of data file are closely related. The key is establishing the relation between logical and physical orders that determine the storage address, in order to enhance the speed of data access.
