17、icense with ANSINot for ResaleNo reproduction or networking permitted without license from IHS-,-,-Data processing gives rise to numerous international exchanges of both intellectual and material nature. These exchanges often become difficult, either because of the great variety of terms used in var
18、ious fields or languages to express the same concept, or because of the absence of or the imprecision of useful concepts. To avoid misunderstandings due to this Situation and to facilitate such exchanges, it is advisable to select terms to be used in various languages or in various countries to expr
19、ess the same concept and to establish definitions providing satisfactory equivalents for the various terms in different languages. In accordance with the directions given to the ISO Sub-Committee in Charge of the Vocabulary, the work on it has been mainly based on the usage to be found in the Vocabu

The Sub-Committee also considered various international documents or drafts issued by ISO Technical Committee 97 and its Sub-Committees and other international organizations (such as the International Telecommunication Union) and national drafts or Standards. The definitions have been drawn u
22、p with the objective of achieving a proper balance between precision and simplicity. The main objective of this Vocabulary is to provide definitions that tan be understood to have the same meaning by all concerned. lt may thus be felt that some definitions are not sufficiently precise, do not includ
23、e all cases, do not take into account certain exceptions, or are in conflict with established uses in particular fields of application. In addition, the Vocabulary consists of several sections prepared over a long period of time and it may be that the preparation of the later sections introduces inc
24、onsistencies with the earlier ones. These imperfections will be eliminated as far as possible in later editions. This procedure allows for immediate publication of needed sections and permits an element of flexibility in the preparation of a comprehensive vocabulary in view of the dynamics of langua

45、 1.1 Introduction This section of the Vocabulary (which will comprise some twenty sections) deals with concepts often used in data processing that are related to mathematics and logic. Concepts concerning numerical quantities are dealt with in the light of the computing methods that may be used with
46、 them. This section deals with general terms concerning the arithmetic operations and logic operations. Tables of dyadic and monadic Boolean operations are attached to this section (annexes A and B); the tables contain symbolic representations of these operations but their purpose is neither to stan
47、dardire the Symbols of Boolean operations nor to set a precedent. Definitions of a number of ad- ditional terms, relating to pure mathematics, are given in annex C. 1.2 scope The Vocabulary is intended to facilitate international communication in data processing. It presents, in two languages, terms
48、 and definitions of selected concepts relevant to the field of data processing and identifies relationships between the entries. In Order to facilitate their translation into other languages, the definitions are drafted so as to avoid, as far as possible, any peculiarity attached to a language. 1.3
49、Field of application The Vocabulary deals with the main areas of data processing, including the principal processes and types of equipment used, the representation, organization and presentation of data, the programming and Operation of Computers, input/output devices and peripheral equipment, as weil as particular applications. 2 PRINCIPLES AND RULES FOLLOWED The sub-clauses under this
