Definition - What does Storage mean?

Storage is a process through which digital data is saved within a data storage device by means of computing technology. Storage is a mechanism that enables a computer to retain data, either temporarily or permanently.

Storage may also be referred to as computer data storage or electronic data storage.

Techopedia explains Storage

Storage is among the key components of a computer system and can be classified into several forms, although there are two major types:

  • Volatile Storage: Requires a continuous supply of electricity to store/retain data. It acts as a computer's primary storage for temporarily storing data. Examples of non-volatile storage include cache memory and random access memory (RAM).
  • Non-Volatile Storage: A type of storage mechanism that retains digital data even if it’s powered off or isn’t supplied with electrical power. This is often referred to as a secondary storage mechanism, and is used for permanent data storage. Examples of volatile storage include hard disk, USB storage and optical media.
