Data storage
Computer storage, or computer memory, refers to the computer components, devices and recording media that retain binary information for some interval of time. In casual language, memory, or active memory usually refers to random-access memory (RAM), or other forms of fast but temporary (non-persistent) storage, while storage or long-term memory typically refers to hard disks (HD) and other forms of storage which are slower to access but persistent when power is switched off.
