Writing How Internet changes the life? You’ve probably known about computers your whole life. But computers have not really been around for very long. Computers started to become popular with big companies in the 1960s. Computers didn’t become widespread in homes and schools until the 1980s. Computers help teachers keep track of lessons and grades. They help students do research and learn. Computers let you hook up to networks (many computers hooked together). They let you hook up to a worldwide network called the Internet. Computers are not just desktops and laptops. Computers are everywhere around your home. There are tiny computer inside microwave ovens, television sets, and videocassette recorders (VCRs) or digital video disc (DVD) players. There are even tiny computers in cars to help them run better. Computers keep getting smaller and more powerful. Personal computers that fit on a desktop today are more powerful than early “supercomputers” that filled entire rooms. Cell phones and watches contain tiny computers that can store information such as telephone numbers, addresses, and appointments. These devices allow you to surf the Web and play games. Many computer experts think that computers have only begun to make their mark on history. 西南大学网络与继续教育学院课程考试试题卷 类别： 网教 专业：计算机教育，计算机科学与技术 2016年 12 月 课程名称【编号】： 专业英语 【0089】 A卷 大作业 满分：100 分 一、大作业题目： 1.
