Computer data storage, often called storage or memory, refers to computer components, devices, and recording media that retain digital data used for computing for some interval of time. Computer data storage provides one of the core functions of the modern computer, that of information retention. It is one of the fundamental components of all modern computers, and coupled with a central processing unit (CPU, a processor), implements the basic computer model used since the 1940s.

  • Computer data storage, often called storage or memory, refers to computer components, devices, and recording media that retain digital data used for computing for some interval of time. Computer data storage provides one of the core functions of the modern computer, that of information retention. It is one of the fundamental components of all modern computers, and coupled with a central processing unit (CPU, a processor), implements the basic computer model used since the 1940s. 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 disk drives, and other types slower than RAM, but of a more permanent nature. Historically, memory and storage were respectively called primary storage and secondary storage. The contemporary distinctions are helpful, because they are also fundamental to the architecture of computers in general. The distinctions also reflect an important and significant technical difference between memory and mass storage devices, which has been blurred by the historical usage of the term storage. Nevertheless, this article uses the traditional nomenclature.
  • En informatique, le stockage d'information est l'enregistrement de l'information sur un support matériel pour sa réutilisation future. Le stockage d'information répond à trois besoins, non exclusifs les uns des autres : conserver l'information en lieu sûr pour répondre à une contrainte légale ou conventionnelle; rendre l'information disponible; réutiliser l'information. Le stockage d'information se fait bien évidemment sur un support d'information électronique, et néanmoins matériel. L'existence même du stockage d'information montre que le terme de dématérialisation, employé pour le passage d'un support d'information papier à un support électronique, est peu approprié, puisque le nouveau support d'information est lui aussi matériel. Le choix de la méthode de stockage se fait selon plusieurs critères : la fréquence d'utilisation de l'information; la criticité de l'information; la pérennité de l'information; la confidentialité de l'information; le volume d'information à stocker; le temps alloué au processus de stockage; et son coût. Le mot d'ordre des techniques de stockage est : plus de capacité, plus vite, plus fiable, et moins cher. C'est pourquoi les types de média sont variés et évoluent souvent.
  • In elettronica una memoria è un dispositivo elettronico che ha come finalità la memorizzazione dell'informazione elettronica.
  • Datalager er en samling av informasjon. Informasjon kan lagres på forskjellige måter. Ny teknologi gjør det mulig å arbeide mer effektivt med å lagre og bruke informasjon. Et datalager som tidligere var basert på lagringsmedia som stein (innriss), lær (pergament) og papir (de to siste skriftbasert) er i løpet av det siste hundreåret, spesielt de siste femti, i stadig sterkere grad supplert med digitale databaserte lagringsmedia. Også muséer og andre kulturinstitusjoner kan defineres som datalager fordi disse er samlinger av informasjon om historiske og andre aktuelle tema.
