We know a computer is a machine that processes data(stored in main memory)into information, under control of a stored program. We also know that, internally, a computer is a binary machine; thus the data and the program instruictions must be stored in binary form. Characters are represented in(71). Numbers are stored as binary numbers, with each bit's positional value significant. A computer's main memory is divided into bytes, words or both(depending on the system), and each of these basic storage units is assigned an(72). Using this address, the processor can read or write selected bytes or words.The processor consists of a clock, an instruction control unit, an arithmetic and logic unit, and registers. Once a program is stored in main memory, the processor can begin to execute it. During(73), the instruction control unit fetches an instruction from main memory; during(74), the arithmetic and logic unit executes it.

共用题干HackingPeople tend to think of computers as isolated machines,working away all by themselves.Some do-personal computer without an outside link, like someone's hideaway（隐蔽的）cabin in the woods.But just as most of homes are tied to a community by streets,bus routes and electric lines,computers that exchange intelligence are part of a community-local,national and even global network joined by telephone connections.The computer network is a creation of the electric age,but it is based on old-fashioned trust. It cannot work without trust. A rogue loose（为所欲为的无赖）in a computer system called hacker（黑客）is worse than a thief entering your house. He could go through anyone's electronic mail or add to,change,distort or delete anything in the information stored in the computer's memory .He could even take control of the entire system by placing his own instructions in the software that runs it.He could shut the computer down whenever he wished,and no one could stop him.Then he could program the computer to erase any sign of his ever having been there.Hacking,our electronic- age term for computer break-in,is more and more in the news-brainy kids vandalizing university records, even pranking（胡闹）about in supposedly safeguard-ed systems.To those who understand how computer networks are increasingly regulating life in the late 20th century,these are not laughing matters.A potential for disaster is building:A dissatis- fled former insurance-company employee wipes out information from payroll（工资表）files. A student sends out a“virus”,a secret and destructive command,over a national network .The vi-rus copies itself at lightning speed,jamming the entire network-thousands of academic,commer-cial and government computer systems.Such disastrous cases have already occurred.Now exists the possibility of terrorism by computer. Spoiling a system responsible for air-traffic control at a busy airport,or knocking out the telephones of a major city,is a relatively easy way to spread panic .Yet neither business nor government has done enough to toughen its defenses against at-tack .For one thing,such defenses are expensive;for another,they may interrupt communica- tion—the main reason for using computers in the first place. Which of the following is NOT mentioned in the passage as an instance of attack by a hacker?A: Deleting information in the computer's memory.B: Shutting down the computer whenever he wishes.C: Entering your house to steal.D: Spoiling a system for air traffic.

Their application in school education has provided teachers and students with new approaches to knowledge and information. There is a heated discussion about whether computers will replace teachers. The following are the supporters’ and opponents’ opinions. Supporters: With the advanced computer and Internet, children can get the learning material whenever they want. Online teaching is becoming more and more popular that students can get planned lessons online. After each class, there is homework for them to do. Both the learning and practice can be done on computers. From computers students can learn something that they are interested in so that they won’t be restricted to the subjects that they are taught at school. Therefore, students will have the opportunity to achieve an all-around development. Opponents: Students need to communicate with teachers and get instructions from them whenever they have troubles in their study. Computers are only cold devices that will affect children’s ability to have face-to-face communication. Education is not only about imparting the knowledge, but also being a useful person. So students need to learn some useful values to be a good person which sometimes cannot be easily learned from computers. Children who use computer will learn to communicate with machines instead of people. There is a risk that they will be a generation of social illiterates.
