Vocabulary aims to facilitate international communication in data processing. It presents in two languages, terms and definitions of concepts relevant to data processing and identifies relationships between entries. To facilitate translation into other languages, definitions are drafted so as to avoid any peculiarity attached to a language. Covers main areas of data processing, including the principal processes and types of equipment used, representation, organization and presentation of data, programming and operation of computers, input-output devices and peripheral equipment, as well as particular applications.
