2 Areas of data processing 1. Business Data processing (BDP) . Business data processing is characterized by the need to establish‚ retain‚ and process files of data for producing useful information. Generally‚ it involves a large volume of input data‚ limited arithmetical operations‚ and a relatively large volume of output. For example‚ a large retail store must maintain a record for each customer who purchases on account‚ update the balance owned on each account‚ and a periodically present a

"The society in which we live in has been so profoundly affected by computers that historians refer to the present time as the information age." (Presley‚ 16) Comments like this show how computers have changed how we live‚ work‚ and play. For example‚ combined with the Internet‚ computers have incorporated many forms of communications into a universal one. The computer’s role in the world continues to grow in importance even as we sometimes take it for granted. We must realize how greatly computers

capabilities like online office‚ online operating system‚ and online resources might push PC manufacturers • The relative technology and know-how needed to make PCs is low. • Due to increased standardization in operating system (by Microsoft) and Microprocessors (by Intel)‚ it is easy for any new entrant to copy and manufacture PCs with no established brand name. • Players like Dell today have shifted to negative working capital because of their strategy of build-to-order. This is an attractive option

Second‚ when AMD created a better microprocessor‚ Intel offered rebates in the form of millions of dollars to the major computer companies in Japan. The company’s that received the rebates agreed to stop buying from AMD. Third‚ Intel coded its software to inhibit the ability of AMD’s microprocessors to run efficiently. Fourth‚ Intel punished computers like Dell when they
