ABSTRACT

One of the things computers do best is manage information. Computers store everything from small collections of personal data, like address books, photo catalogs, and financial records, to huge databases containing scientific data, medical records, and corporate finances. People constantly use their computers to search for information, whether it’s in a music library on a personal computer, or at a commercial music site, or even across the entire Internet. Computers also spend a lot of time rearranging data to make it easier for users to find what they need.
