Information storage

Abstract

When it comes to archiving, storing, and recording information, either temporarily or permanently, the needs of modern society never cease to grow. It is not easy to draw up a panoramic view of this phenomenon, given the enormous range of storage media and devices that have been devised to answer so many specific data storage requirements. However, a basic division can be made between permanent storage of large amounts of data (hard disks, CDs, DVDs, etc.) and storage associated with data processing (active and read only memory in computers, flash compact cards in digital cameras, etc.). Table 15.1 illustrates some of these features.
