Debugging is the process of analyzing and locating bugs when software does not behave as expected. Software testing is a much more means of identifying software .Therefore, debugging supports testing other than replacing testing.2. ASCIIASCII is the _________ for American Standard Code for Information __________. ASCII is a ________ for representing English characters as numbers, with each letter assigned a number from 0 to 127(decimal). For example, the ASCII code for uppercase M is 77 (decimal). Most computers use ASCII codes to represent text, which makes it possible to ________ data from one computer to another.Text files stored in ASCII format are sometimes called ASCII________ . Text editors and word processors are usually capable of storing data in ASCII format, although ASCII format it notalways the ________ storage format. Most data files, particularly if they contain numeric data, are not stored in ASCII format. Executable programs are never stored in ASCII ________ .The ____________ASCII character set uses just 7 bits for each character. There are several larger character sets that use 8 bits, which gives them 128 additional _____________. The extra characters are used to represent non-English characters, graphics symbols, and mathematical symbols. Several companies and organizations have proposed ________ for these 128 characters. The DOS operating system uses a superset of ASCII called extended ASCII or high ASCII. A more universal standard is the ISO Latin 1 set of characters, which is used by many operating systems, as well as Web browsers. Another set of codes that is used on large IBM computers is EBCDIC.3. The Operating SystemThe operating system is a ______ of system programs that, when executed, controls the ________ of the computer.

For PCs, the most popular operating systems are DOS, 0S/2, and__________, but others are _________, such as Linux.四、阅读选择题（每小题2分，共20分）Passage 1The Internet, then known as ARPANET, was brought online in 1969, which initially connected four major computers at universities in the southwestern US . The early Internet was used by computer experts , engineers, scientists, and librarians. There was nothing friendly about it. There were no home or office personal computers in those days, and anyone who used it, whether a computer professional or an engineer or scientist or librarian, had to learn to use a very complex system.The Internet matured in the 1970's as a result of the TCP/IP architecture. As the commands for E-mail, FTP, and telnet were standardized, it became a lot easier for non-technical people to learn to use the nets. It was not easy by today' s standards by any means, but it did open up use of the Internet to many more people in universities in particular. Other departments besides the libraries, computer, physics, and engineering departments found ways to make good use of the nets -- to communicate with colleagues around the world and to share files and resources.In 1991, the first really friendly interface to the Internet was developed at the University of Minnesota. The University wanted to develop a simple menu system to access files and information on campus through their local network.Since the Internet was initially funded by the government, it was originally limited to research, education, and government uses. Commercial uses were prohibited unless they directly served the goals of research and education. This policy continued until the early 1990's, when independent commercial networks began to grow.Choose the best answer according to Passage.（根据上文的内容选择正确的答案。

Among other things, its configuration determines whether a computer is fast or slow in relation to other computers. The CPU is the most complex computer system component, responsible for directing most of the computer system activities based on the instructions provided. As one computer generation has evolved to the next, the physical size of the CPU has often become smaller and smaller, while its speed and capacity have increased tremendously. Indeed, these changes have resulted in microcomputers that are small enough to fit on your desk or your lap.The CPU comprises the control unit and the arithmetic / logic unit (ALU). The control unit is responsible for directing and coordinating most of the computer systems activities. It determines the movement of electronic signals between main memory and the arithmetic/logic unit, as well as the control signals between the CPU and input/output devices.The ALU performs all the arithmetic and logical (comparison) functions —that is, it adds, subtracts, multiplies, divides, and does comparisons. These comparisons, which are basically “less than”, “greater than”, and “equal to”, can be combined into several common expressions, such as “greater than or equal to”. The objective of most instructions that use comparisons is to determine which instruction should be executed next.（二）Tell whether the following statements are true(T) or false(F) according to the passage A.（根据上文的内容判断下列句子的正误，共10分，每题2分）1. With the development of computer, the physical size of the CPU has often become bigger and bigger. ( F )2. The movement of electronic signals between main memory and the ALU as well as the control signal between the CPU and input /output devices are controlled by the control unit of the CPU. ( T )3. The CPU comprises the control unit and memory. ( F )4. The control unit performs all the arithmetic and logical (comparison) functions . ( F )5. The central processing unit (CPU) is the heart of the computer systems. ( T )Passage BA computer virus is a computer program that is created to make and spread copies of itself. The program may however also be designed to have other effects on the systems it infects, ranging from the annoying to the disastrous. Virus attacks are growing rapidly these days. According to BusinessWeek, the 76,404 attacks reported in the first half of 2003 nearly match previous year's total number . As new antivirus tools are more powerful than before, the virus writers are getting a lot smarter with newer and creative ways to attack network systems. Let's first examine some common virus types:Basic Virus - a piece of software code that is developed to attack computers and network systems via email or Internet connections. It quickly replicates itself and gradually attaches to files, programs or the hard drive.Trojan Horses - This is a program that doesn't replicate when entering a system but can be effectively used to open 'back doors.' Trojan Horses allow hackers to take control over a particular system or to steal very important data.Worm - this type of virus is able to spread itself automatically over the network from one computer to the next. During a worm attack, users' computers get infected without even having to click open email attachment or any program, etc.Since it is very difficult to avoid the virus, your best defense is a powerful antivirus program. In order to fight with such viruses, the software vendorsshould focus on making their products more robust. This may ask for a trade-off between user-friendliness and security. In specific cases it may require line-by-line inspection, code retooling and even systems automation to defend the installed programs.（三）choose the best answer according to the passage B.（根据上文的内容选择正确的答案，共10分，每题2分）1．A computer virus is a computer program that is created to make and spread C of itself.A．programs B．virus C． copies D．files2．Worm spread itself except by D .A．network B．E-mail C．program D．hardware 3．Antivirus program can scan and A virus.A．clean B．produce C．replicate D．make4．Trojan Horses C .A．quickly replicate itself and gradually attach to files, programs or the hard drive.B．infect the computer without even having to click open email attachment or any program.C．allow hackers to take control over a particular system or to steal very important data.D．avoid the virus to attack computer.5．According to Business Week, the B attacks reported in the first half of 2003 nearly match previous year's total number .A． 86,404 B． 76,404 C．56,354 D．34,876Passage CThe Internet, then known as ARPANET, was brought online in 1969, which initially connected four major computers at universities in the southwesternUS . The early Internet was used by computer experts , engineers, scientists, and librarians. There was nothing friendly about it. There were no home or office personal computers in those days, and anyone who used it, whether a computer professional or an engineer or scientist or librarian, had to learn to use a very complex system.The Internet matured in the 1970's as a result of the TCP/IP architecture. As the commands for E-mail, FTP , and telnet were standardized, it became a lot easier for non-technical people to learn to use the nets. It was not easy by today' s standards by any means, but it did open up use of the Internet to many more people in universities in particular. Other departments besides the libraries, computer, physics, and engineering departments found ways to make good use of the nets -- to communicate with colleagues around the world and to share files and resources.In 1991, the first really friendly interface to the Internet was developed at the University of Minnesota. The University wanted to develop a simple menu system to access files and information on campus through their local network.Since the Internet was initially funded by the government, it was originally limited to research, education, and government uses. Commercial uses were prohibited unless they directly served the goals of research and education. This policy continued until the early 1990's, when independent commercial networks began to grow.（四）Choose the best answer according to Passage C.（根据上文的内容选择正确的答案，共10分，每题2分）1. How many computers were connected to the initial Internet in 1969 ? BA. TenB. FourC. TwentyD. Three2.

Which statement is not true according to Passage C? DA. Many more people in universities began to use the Internet in the 1970s, but it wasn't as user-friendly as today's standards.B. The restrictions to commercial uses changed as the independent commercial networks were not funded by the government.C. Commercial uses were allowed for the early Internet if they directly served the goals of research and education.D.
