12、iven below, and change the form where necessary (从下面所列词语中选择合适的词语, 以其适当的形式填空)(5%) high-level language assembly language writtenmachine language notationA programming language, designed to facilitate the communication between human and computers, is a _ for describing computation in readable form. The

13、re are 3 levels of programming languages, they are _, which can be run directly by computer; _and_. There are different high-level programming languages. Fortunately, most of them have many kinds of construct in common and vary only in the way that these must be_ . Therefore, first thing to be decid

14、ed about a task is to choose which programming language is best suited for the job.Passage AThe hardware of a digital computer system is divided into four functional sections. The block diagram of Fig.2-4 shows the four basic units of simplified computer: the input unit, central processing unit, mem

15、ory unit, and output unit. Each section has a special function in terms of overall computer operation.Fig.2-4 A Digital Computer The central processing unit (CPU) is the heart of the computer system. It is responsible for performing all arithmetic operations and logic decisions initiated by the prog

16、ram. In addition to arithmetic and logic functions, the CPU controls overall system operation. There are two main sections found in the CPU of a typical personal computer system: the arithmetic-logic section and the control section. But these two sections are not unique to personal computer. They ar

17、e found in CPUs of all sizes.Every processor comes with a unique set of operations such as ADD, STORE, or LOAD that represent the processors instruction set. Computer designers are fond of calling their computer machines, so the instruction set is sometimes referred to as machine instruction and the

18、 binary language in which they are written is called machine language.The memory unit of the computer is used to store information such as numbers, names, and addresses. By “store”, we mean that memory has the ability to hold this information for processing or for outputting for later time. The prog

19、rams that define how the computer is to process data also reside in memory.In computer system, memory is divided into two different sections, known as main storage and auxiliary storage. They are also sometimes called internal memory and external memory respectively. External memory is used for long

20、 term storage of information that is not in use. For instance, it holds programs, files of data, and files of information. In most computers, this part of memory employs storage on magnetic media such as magnetic tapes, magnetic disks, and magnetic drums. This is because they have the ability to sto

21、re large amount of data. Internal memory is a smaller segment of memory used to temporary storage of programs, data, and information. For instance, when a program is to be executed, its instructions are first brought from external memory into internal memory together with the files of data and infor

22、mation that it will affect. After this, the program is executed and its files updated while they are held in internal memory. When the processing defined by the program is completed, the updated files are returned to external memory. Here the program and files are retained for use at later time. (二)

23、 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) (10%)1. The four basic units of simplified computer: the input unit, central processing unit, memory unit, and output unit. ( )2. The CPU is responsible for performing some arithmetic operatio

24、ns and logic decisions. ( ) 3. “ADD AX, BX” is an instruction of machine language. ( )4. Main storage and auxiliary storage are sometimes called internal memory and external memory respectively. ( )5. The binary language which they are written in machine instruction is called machine language. ( ) P

25、assage BIn order to solve a computational problem, its solution must be specified in terms of a sequence of computational steps, each of which may be performed by a human or a digital computer. If you want to solve the computational problem with a computer, you should learn how to program. The task

26、of developing programs for the solution of computational problems is referred to as programming. Computer programming is the process of planning and creating a sequence of steps for a computer to follow. In general, this process will help us resolve a problem, which is either too tedious or difficul

27、t to work out otherwise. So programming is breaking a task down into small steps.Programming is sometimes contrasted with coding. Coding generally refers to the writing of programs for given program specification, while programming includes the task of preparing the program specification as well as

28、that of writing the program. The text of a program is sometimes referred to as code, and lines of program text are referred to as lines of code, especially in the case of machine-language programs. The term coder is used to describe a person engaged exclusively in implementing program specifications

29、 prepared by others. Whats actually involved in programming - the actual process of writing programs? Heres a quick overview of the process: Write a program. Compile the program. Run the program. Debug the program. Repeat the whole process until the program is finished. (三) Choose the best answer ac

In order to solve a computational problem, you can let a person or a _to do it.A. machine B. computer C. keyboard D. mouse5. Which of the following is not the stage of programming? _.A. Wri

32、te a program.B. Debug the program.C. Print the program.D. Compile the program.Passage CA 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 th

33、e disastrous. Virus attacks are growing rapidly these days. According to Business Week, the 76,404 attacks reported in the first half of 2003 nearly match previous years total number. As new antivirus tools are more powerful than before, the virus writers are getting a lot smarter with newer and cre

34、ative ways to attack network systems. Lets 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

35、.Trojan Horses - This is a program that doesnt 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 t

36、he 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, t

37、he software vendors should 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.(四) Choose the best answer
