On the Characteristics of the English Computer Lexis
Introduction
Owing to changes in global politics, economy, and development of science and technologies, English vocabulary enlarges faster than ever before.This is especially true when the computer appeared. Since the world entered the 21st century, computer develops rapidly and tremendously. It comes into our daily life in different aspects. To face the computer age, it is important to understand the characteristics of the English Computer lexis.
The paper has an aim to analyze the characteristics and situation of the computer lexis.and to show its translation style and professional attribute and usage characteristics of computer English.
In this thesis I will describe the development and situation of the computer lexis first, an
Research Questions
Question 1:What is English Computer Lexis and what characteristics does it have?
Question 2:What are the ways of word-formation about computer vocabulary and what is the difference compared with traditional word-formation?
Question 3:What is the application fields of computer lexis and how can we understand the characteristics of cmputer lexis efficiently?
Literature Review
The advent of computer was in the 1940s. Its development was only in its embryonic phrase, but already many now-familiar elements of computational terminology were falling into place, analogue and digital; bit, data and memory; language and program; punchcard and imput. In the 1950s, computers were starting to move out of university laboratories into commercial establishments. Yuan Hongjie(2005) has argued that artificial intelligence, information technology, and data processing had their beginnings and terms like bootstrap and modem, on line and real time, print-out and RAM and FORTRAN entered English. The 1960s saw the greatest lexical advances in computer science. Yang Lin(2002) has held that as computeracy spread and one by one various aspects of our lives became computerized, we would learn the significance of bytes, chips, cursors, databases, mice and software. We could format and access to computers, fluent in ASCII, BASIC, and Cobol. And for our leisure moments, there were computer games. In 1970s, the computer continued its march towards the center of our lives, bringing amounts of new terminology: floppy disk and hard disk, microprocessors and window and the dreaded virus. We acquired personal computers or word processors and to print results of our labors, the dot matrix, the daisy wheel, and later the laser printer. We could communicate via the Ethernet and have barely heard of hacking and the need of data protection. In the 1980s, cyberspace infiltrated the interstices of the everyday world. Computer technology leaped ahead, enriching the English language. Only an ageing minority were not, it seemed, computerate, and able to cope with booting, down loading, and dragging. It was the decade which saw the beginning of the Internet and information highway, of e-mail，of domains and newsgroups.。In 1990s cybernauts and netties surfed the WWW, to be in the swim you had to have your own website or homepage , you would hope to avoid the spam and mail bombs , but the main fear is millennium bug. From the historical review we can see how computer changes our lives and our language.
As Zhang Minfang(2004) analysed: First, the introduction consists of three parts. The first briefly reviews the theory of language and language study, pointing out the aim of this study.The second give the definition of computer English words in three aspects: strings of letters and words used in programming and processing, technical terms, and casual expressions used by computer enthusiasts.The third describes the language change under the effect of computer technology. The computer technology has swept into the English vocabulary and given birth to a wide array of new words and phrases – computer English words.Second,Word Formation of Computer English Words Computer English employs different word formation devices to form large amount of computer English words. By studying these morphological rules of word formation, the characteristics of computer English words can be realized. The major methods of word formation in computer English words include compounding, affixation, conversion, blending, acronyms, clipping and eponyms.Third, Characteristics Analysis of Computer English Words The Computer English words surely should belong to the category of EST (English for Science and Technology) words. While keeping some general features of EST words they still maintain some striking features, which distinguish themselves from EST words. Brevity, popularity, and vividness are their characteristics. Shortened words take a large proportion of computer English words, and enormous floods of shorted words are used in computer English. So computer English words possess features of brevity. Three motivations for the use of shortening are social and historical motivation, psychological motivation and technological motivation.Computer English words, which differ from general EST words, do not use many highly technical words but a large member of sub-technical words. Computer English borrows from general English a great amount of everyday words.
Expected results
With an researching focus on the characteristics of English computer lexis, the paper is expected to be helpful in understanding development and situation of the computer lexis as well as characteristics and ways of word-formation about computer lexis.
