The microprocessor, also called a processor, is the "brain" of your computer. This is where your computer interprets and processes information. (6’) 2、The serial port is a connector on the back of the computer. You can use it to add hardware to your computer, such as a plotter, serial printer, or external modem. You have two serial ports in your computer, Serial B and Serial A. (6’) 3. DOS uses a special program called a "device driver" to control each device. For example, DOS uses a built-in device driver to control how information is read to and from a diskette drive. DOS has built-in device drivers for your keyboard, display, hard and diskette drives, and communication ports. Because these device drivers are built in, you do not have to do anything special to use them. You can customize certain features of these devices by using CONFIG.SYS commands. (8’) 4. The word “hacker” has taken on many different meanings ranging from 1) “a person who enjoys learning the details of computer systems and how to stretch their capabilities” to 2) “a malicious or inquisitive meddler（恶意的或爱管闲事的人）who tries to discover information by poking around., possibly by deceptive or illegal means ...” (6’) 得分 阅卷人 Welcome to the Web! The Internet and the World Wide Web are great places to be right now. We use the term "place" because so many of the things you can do online are similar to the things you can do wherever people gather together–––in homes, schools, libraries, shopping malls (步行街), or at family reunions or town meetings. The Net allows people to learn, shop, find crucial information, and to participate in communities, whether they're local, global, or simply virtual. But Is It Useful? The Web is useful: You can find old friends online. You can research and book flight reservations. Check the weather. Check out your high school or college alma mater（母校）. Find breaking news. Research political issues. Follow your stock portfolio（股票等价目表）. Place a classified ad. And, of course, more and more vendors are setting up shop on the Web. Books. CDs. Computers. even Cars. You can learn how to do some of these activities in later sections of this tutorial. The Internet is also fun. You can write to old friends. Or check out their web pages. Enjoy web-based soap operas. Laugh at online jokes. Join in a live Net Event. Chat with other Internet surfers. Pick a fake stock portfolio. Check to see if your name appears anywhere on the Web. Do wacky random searches. Millions of users log on to the Net every day, and it's not just to do research. There's a lot of fun out there.
