These
16、exchanges often become difficult, either because of the great variety of terms used in various 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
17、 advisable to select terms to be used in various languages or in various countries to express 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 t
18、he Vocabulary, the work on it has been mainly based on the usage to be found in the Vocabulary o f in forma tion processing * established and published by the International Federation for Information Processing and the International Computation Centre, and in the USA Standard vocabulary for informa
19、tion processing established, published and revised by the American National Standards Institute. 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 Te
20、lecommunication Union) and national drafts or Standards. The definitions have been drawn up 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 concer
21、ned. lt may thus be felt that some definitions are not sufficiently precise, do not include 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 l
22、ong period of time and it may be that the preparation of the later sections introduces inconsistencies 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 flex
23、ibility in the preparation of a comprehensive vocabulary in view of the dynamics of language. * North Holland Publishing Company - AMSTERDAM 1966 iV Le traitement de Iinformation donne lieu 5 de tres nombreux echanges internationaux dordre intellectuel ou materiel qui sont souvent rendus difficiles

Pour eviter les malentendus ayant leur origine dans Ie vocabulaire et faciliter les echanges, il convient
25、 de proceder a un choix des termes a employer dans les differentes langues ou dans les differents pays pour designer Ia meme notion, et de rediger des definitions assurant une equivalence pratiquement satisfaisante entre ces differents termes.

40、L STANDARD NORME INTERNATIONALE ISO 2382/1 I-l976 (E/F) Data processing - Vocabulary - Section 02 : Arithmetic and logic operations 1 GENERAL 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
41、to mathematics and logic. Concepts concerning numerical quantities are dealt with in the light of the computing methods that may be used with them. This section deals with general terms concerning the arithmetic operations and logic operations. Tables of dyadic and monadic Boolean operations are att
42、ached to this section (annexes A and B); the tables contain symbolic representations of these operations but their purpose is neither to standardire 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 ann
43、ex C. 1.2 scope The Vocabulary is intended to facilitate international communication in data processing. It presents, in two languages, terms and definitions of selected concepts relevant to the field of data processing and identifies relationships between the entries. In Order to facilitate their t
44、ranslation into other languages, the definitions are drafted so as to avoid, as far as possible, any peculiarity attached to a language. 1.3 Field of application The Vocabulary deals with the main areas of data processing, including the principal processes and types of equipment used, the representa
45、tion, 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 heading included in ISO 2382/1 are equally applicable to this section
46、. They are not reproduced here. The corresponding sub-clause headings are the following : Traitement de Iinformation - Vocabulaire - Chapitre 02 : Opkations arithmetiques et logiques 1 GENiRALITiS 1.1 Introduction Le present chapitre du Vocabulaire (qui en comprendra une vingtaine) contient des noti
47、ons souvent employees en traitement de Iinformation concernant les mathematiques et Ia logique. Les notions concernant les grandeurs numeriques sont traitees suivant les methodes de calcul qui peuvent leur etre appliquees. Le present chapitre comprend les termes generaux concernant les operations ar
48、ithmetiques, les operations logiques. Les tableaux des operations booleennes diadiques et monadiques sont joints au present chapitre (annexes A et B). Ces tableaux contien- nent les representations symboliques de ces operations, mais nont pas pour objet de normaliser ces Symboles ni de constituer un
49、 precedent. Des definitions dun certain nombre de termes complementaires, relatifs aux mathe- matiques pures, sont donnees dans Iannexe C. 1.2 Objet Le Vocabulaire a pour objet de faciliter les echanges internationaux dans ce domaine. II presente un ensemble bilingue de termes et de definitions ayant trait a des notions choisies, et definit les relations pouvant exister entre differentes notions.
