Computer programs have undergone many changes during this time in response to user need and advances in technology. Newer ideas in computing such as parallel computing, distributed computing, and artificial intelligence, have radically altered the traditional concepts that once determined program form and function. In parallelcomputing parts of a problem are worked on simultaneously by different processors, and this speed up the solution of the problem. Another type of parallel computing called distributed computing use CPUs from many interconnected computers to solve problems. Research into artificial intelligence (AI) has led to several other new styles of programming.2.High-level languages are commonly classified asprocedure-oriented, functional, objected-oriented, logic languages. The most common high-level languages today are procedure-oriented languages. In these languages, one or more related blocks of statements that perform some complete function are grouped together into a program module, or procedure, and given a name such as “procedure A”. If the same sequence of operations is needed elsewhere in the program, a simple statement can be used to refer back to the procedure. In essence, a procedure is just a mini-program. A large program can be constructed by grouping together procedures that perform different tasks.四、汉译英题（20分）最著名的互联网例子是因特网。

These activities may involve the development of software from scratch in a standard programming language like Java or C. Increasingly, however, new software is developed by extending and modifying existing systems and by configuring and integrating off-the-shelf software or system components.Software processes are complex and, like all intellectual and creative processes, rely on people making decisions and judgments. Because of the need for judgment andcreativity, attempts to automate software processes have met with limited success. Computer-aided software engineering (CASE) tools can support some process activities. However, there is no possibility, at least in the next few years, of more extensive automation where software takes over creative design from the engineers involved in the software process.Although there are many software processes, some fundamental activities are common to all software processes:1). Software specification The functionality of the software and constraints on its operation must be defined.2). Software design and implement-ation The software to meet the specification must be produced.3). Software validation The software must be validated to ensure that it does what the customer wants.4). Software evolution The software must evolve to meet changing customer Needs. Although there is no ‘ideal’ software process, there is scope for improving the software process in many organizations. Processes may include outdated techniques or may not take advantage of the best practice in industrial software engineering. Indeed, many organizations still do not take advantage of software engineering methods in their software development.(1)、A software process is _______.•product•standard programming language•existing system正确答案：B(2)、Software processes ___________.•complex and intellectual enough to be developed byComputer-aided software engineering (CASE) tools.•rely on Computer-aided software engineering(CASE) tools.•depend on the people making decisions and judg ments正确答案：A(3)、software processes usually include ________ activities.•••正确答案：C(4)、Improving the software process in many organizations is ______.•••正确答案：D(5)、Software design and implementat-ion means that _________.•functionality of the software and constraints on its o peration must be defined.•software must be validated to ensure that it does w hat the customer wants.•software must evolve to meet changing customer Ne eds.正确答案：B。

Comprehension（阅读理解，40分）( )（一）Fill in the blanks with suitable words or expressions from the list given below, and change the form where necessary. （从下面方框中选择合适的词或表达，以其适当的形式填空，共10分, 每空2分)high-level language assembly language writtenmachine language notationA programming language, designed to facilitate the communication between human and computers, is a _ notation _ for describing computation in readable form. There are 3 levels of programming languages, they are_ machine language _ , which can be run directly by computer; ___ assembly language __ and _ high-level language _. 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 _ written __ . Therefore, first thing to be decided about a task is to choose which programming language is best suited for the job.Passage AThe central processing unit (CPU) is the heart of the computer systems. 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. Only A could use the early Internet.A. computer experts, engineers, scientists, and librariansB. any experts, engineers, scientists, and librariansC. computer experts, engineers, scientists, and studentsD. experts, engineers, and scientists in universities in US3.

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. The early Internet was logged in from home or office personal computers.Ⅲ.Translation（翻译，30分）(一) Translate the following sentences into Chinese.（将下列句子翻译成汉语，每题5分）1.

计算机专业英语作业：1、请将视频“什么是电脑硬件”中所述内容用英文表示。
2、请将以下英文翻译为中文。
1）Plug and Play, sometimes, abbreviated PnP, is a catchy phrase used to describe devices that work with a computer system as soon as they are connected. The user does not have to manually install drivers for the device or even tell the computer that a new device has been added. Instead the computer automatically recognizes the device, loads new drivers for the hardware if needed, and begins to work with the newly connected device.For example, if you connect a Plug-and-Play mouse to the USB port on your computer, it will begin to work within a few seconds of being plugged in. A non plug-and-play device would require you to go through several steps of installing drivers and setting up the device before it would work.While Plug and Play usually refers to computer peripheral devices, such as keyboards and mice, it can also be used to describe internal hardware. For example, a video card or hard drive may be a Plug and Play device, meaning the computer will recognize it as soon as it is installed. The only difference is that internal components usually require the computer to be turned off when they are installed, while external devices can typically be installed while the computer is running.2）What are some examples of computer peripheral devices?Answer:⏹ A computer peripheral, or peripheral device, is an external object that provides input and output for the computer.⏹Some common input devices include: keyboard, mouse, joystick, pen tablet, MIDI keyboard (musical instrument digital interface数码音响), scanner, digital camera, video camera, microphone.⏹Some common output devices include: monitor, projector, TV screen, printer, plotter, speakers.⏹There are also devices that function as both input and output devices, such as: external hard drives, media card readers, digital camcorders, digital mixers, MIDI equipment.⏹While these are some of the more common peripherals, there are many other kinds as well. Just remember that any external device that provides input to the computer or receives output from the computer is considered a peripheral.3）Binary is a two-digit (Base-2) numerical system, which computers use to store data and compute functions. The reason computers use the binary system is because digital switches inside the computer can only be set to either on or off, which are represented by a 1 or 0. Though the binary system consists of only ones and zeros, the two digits can be used to represent any number.4）There are many types of compact disks. One format is called CD-RWs. They can be recorded on and re-recorded on (rewritten on) as you would do with a floppy disk. Another format is the CD-ROM. The technology for recording on these disks is different form other CDs.5）Stands for "Read-Only Memory." Please do not confuse this term with RAM or a hard drive, as many people already do. ROM is memory containing hardwired instructions that the computer uses when it boots up, before the system software loads. In PCs, the instructions are read from a small program in the ROM, called the BIOS (Basic Input/Output System).6）disk driveA machine that reads data from and writes data onto a disk. A disk drive rotates the disk very fast and has one or more heads that read and write data. There are different types of disk drives for different types of disks. For example, a hard disk drive (HDD) reads and writes hard disks, and a floppy drive (FDD) accesses floppy disks. A magnetic disk drive reads magnetic disks, and an optical drive reads optical disks. Disk drives can be either internal (housed within the computer) or external (housed in a separate box that connects to the computer). Disk drives can be either internal (housed within the computer) or external (housed in a separate box that connects to the computer).7）removable disktype of disk drive in which hard disks are enclosed in plastic or metal cartridges so that they can be removed like floppy disks. Removable disk drives combine the best aspects of hard and floppy disks. They are nearly as capacious and fast as hard disks and have the portability of floppy disks. Their biggest drawback is that they're relatively expensive.8）serial portA port, or interface, that can be used for serial communication, in which only 1 bit is transmitted at a time. A serial port is a general-purpose interface that can be used for almost any type of device, including modems, mice, and printers (although most printers are connected to a parallel port).9）parallel portA parallel interface for connecting an external device such as a printer. Most personalcomputers have both a parallel port and at least one serial port.10）Pseudocode (derived from pseudo and code) is a compact and informal high-level description of a computer programming algorithm that uses the structural conventions of some programming language, but typically omits details that are not essential for the understanding of the algorithm, such as subroutines, variable declarations and system-specific code.11）2.5 Using Function KeysYour computer has 12 function keys, F1 through F12. The functions assigned to these keys differ for each application. You should refer to you software documentation to find out how these keys are used.The [FN] key provides extended functions for the notebook and is always used inconjunction with another key.Fn+F1 SleepThis function will put the E1245 notebook into sleep mode. The LCD will switch off and devices will switch to lower power mode.Fn+F2 Fan ControlThis function will enable or disable the Silent Fan function . This will enable the user to put the fan into quiet mode if the user needs the notebook o be quieter.Fn+F3 Mute V olumeThis function will mute the volume control in Windows and all sound output from the speakers will stop. Pressing this combination again will enable sound output.Fn+F4 LCD/Display-Out SwitchThis function will switch the display configuration for the E1425 -It will cycle between 3 modes depending on operation system settings. These 3 Modes are:LCD Only-Image on the E1425 LCDDisplay Only-Image on external monitorLCD+Display-Image on LCD and external monitor12）课本P89 EX.5 把下列短文翻译成中文。

From there，they are output to a display screen ( the basic output device )，where the user can see them．If a permanent copy of the output is required，it can be sent from memory to a printer．Computers are not limited to character output，however，many systems support graphics．A screen is divided into a number of points called pixels．Images are formed by selectively turning the pixels on and off．A screen’s reso1ution is a function of the number of pixels．We briefly considered several other input and output devices and media，including punched cards，various types of printers，magnetic media, optical media, terminal，and voice I／O．Finally，we turned to the problem of linking input and output devices to a computer system．Each device is electronically different，but the computer always deals with a common code．An interface board serves to bridge this gap．An input device sends its data to the interface，which converts the data from the external device’s form to the computer’s internal form and stores them in main memory. On output，information moves from memory to the interface，where it is converted to the external device’s form，and output．A buffer can help to adjust for the speedDifferential between adjacent devices；On larger computers，each external device is linked to a control unit．The control units are plugged into channels，and the channels are connected to the computer．In this chapter，we have focused on input and output，showing how human beings communicate with a computer．One of the advantages of putting data into a computer is that，once they have been converted to electronic form，they can be used over and over again．In the next chapter，we’ll consider long—term secondary storage．。
