A computer is an electronic device that accepts and processes information mathematically or logically according to programmed instructions. The results of this processing are displayed visually, printed on paper, played audibly, kept in electronic form for transfer to other computers, or used to control some other device or process.
Modern computers have become a universal tool, used in most occupations. The Internet itself, including Curlie, this Internet directory, is written on computers, stored on computers, presented by computers, and usually viewed on computers. By that standard every site could be listed under this category. but instead, this category contains listings of sites primarily about the use of Computers other than for a purpose fitting one of the other top level categories. Sites about the artistic use of computers can be found in Arts, about scientific use of computers in Science, etc.
