storage

In computer science, storage refers to any computing hardware that is used to store digital data. It encompasses a wide variety of technologies, including primary storage like RAM and ROM, as well as secondary storage such as hard disk drives, solid-state drives, and optical media. Storage is essential for retaining data, instructions, and information for future use. It is characterized by its capacity (how much data it can hold), access speed (how quickly data can be read or written), volatility (whether it retains data when power is off), and cost.
