回答下列各题 Educators today are more and more often heard to say that computerliteracy is

absolutely necessary for college students. Many even argue that eachincoming freshman should have permanent access to his or her own microcomputer. What advantages do computers offer the collegestudents？ Any student who has used a word processor will know one compellingreason to use a computer: to write papers. Although not all students feelcomfortable composing on a word processor, most find revising and editing much easier on it. One can alter, insert, or delete just by pressinga few keys, thus eliminating the need to rewrite or re-type.Furthermore, since the revision process is less burdensome, students are morelikely to revise as Often as is necessary to end upwith the best paper possible. For these reasons, many freshman English coursesrequire the use of a word processor. Computers are also useful in the context of language courses,where they are used to drill students in basic skills. Software programs reinforce ESL(Englishas a Second Language ) instruction, as well as instruction in French, German, Spanish, and other languages. By using theseprograms on a regular basis, students can improve their proficiency in a language while proceeding at their ownpace. Science students take advantage of computers in many ways. Usingcomputer graphic capabilities, for example, botany students can represent andanalyze different plant growth patterns. Medical students can learn to interpret computerized images of internal body structures. Physicsstudents can complete complex calculations far more quickly than they could without the use of computer. Similarly, business and accounting students find that computerspreadsheet programs are all but indispensable to many aspects of their work, while studentspursuing careers in graphic arts, marketing, and public relations find that knowledge of computer graphic is important. Education majors learnto develop grading systems using computers,while social science students usecomputers for analyzing and graphically displacing their research results. It is no wonder, then, that educators support the purchase and useof microcomputers by students. A versatile toot, the computer can help studentslearn. And that is, after all, the reason for going to college. The word "literacy" (Line 1, Paragraph 1)means__________.
