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。

Qian Liang is asking Mr. Wu about software development. Qian Liang: Excuse me, Mr. Wu. Would you please tell me something about requirements analysis in software engineering? Mr. Wu: Of course. The hardest part of building a software system is deciding what to develop, and the hardest conceptual work is to establish detailed technical requirements, including all the interfaces to users, to machines and to other software systems. Meanwhile, it is also the part that cripples the resulting systems if done wrong, so it is most difficult to rectify later. Qian Liang: That’s what I refer to as “requirements analysis”, isn’t it? My understanding is that so long as we spend enough time communicating, anything wrong might be warded off.
高等教育出版社影印版计算机专业英语习题5ch-7-im
I. Ch 5 Input and OutputLecture OutlineA. Competencies pg 1761. Define input.2. Describe keyboard entry, pointing devices, andscanning devices.3. Discuss image capturing devices, digitizing devices,and audio input devices.4. Define output.5. Describe monitors, printers, and audio output devices.6. Discuss combination input and output devices.B. Introduction pg 177▪Computer Input and output devices are essentially translators.▪Input devices translate numbers, letters and actions that people understand into a form that the computer can process.▪Output devices translate the machine language the computer can process back into letters, numbers, sounds, and images that people can understand.▪Competent end users need to know about the most common input devices such as keyboards, mice, scanners, digital cameras, digitizing tablets,voice recognition devices, and MIDI.▪They also need to know about the most common output devices such as monitors, printers, and audio output.▪They also need to know about combination input/output devices such as fax machines, Internet telephones, and terminals.C. What is Input pg 178▪Input is any data or instructions that are used by a computer.▪They can come directly from you or from other sources.▪Input devices are hardware used to translate words, sounds, images, and actions that people understand into a form that the system unit can process.D. Keyboard Entry pg 178▪Keyboards convert numbers, letters, and special characters into electronic signals.▪Most keyboards have their alphabetic characters arranged in the standard QWERTY format (note the first six characters on the top row of akeyboard).1. Keyboards▪Traditional keyboards: full-sized, rigid, rectangular keyboards that include function, navigational, and numeric keys.▪Flexible keyboards: fold or roll up for easy packing and storage for mobile users.▪Ergonomic keyboards: similar to traditional, but designed tospecifically alleviate wrist strain associated with repetitivemovements of typing.▪Wireless keyboards: more expensive than traditional keyboards, but give the flexibility of un-tethering the cord.▪PDA keyboards: miniature keyboards for PDAs for sending email, etc.2. Features▪Numeric keypads: easier entry of numbers and arithmetic symbols▪Toggle keys: on off keys for such things as Caps Lock and Scroll Lock▪Combination keys: perform an action when combined with other keys, e.g. <Ctrl> key or <Alt> keyE. Pointing Devices pg 1801. Mouse▪ A mouse controls the pointer displayed on the monitor▪The mouse pointer usually appears in the shape of an arrow▪Mechanical mouse: traditional mouse with a ball in the bottom and cord connecting it to the computer▪Optical mouse: has no moving parts – it emits and senses light to detect mouse movement.▪Cordless or wireless mouse: a battery operated device thattypically uses radio waves or infrared light waves to communicatewith the system.▪Other similar pointing devices include:▪Trackball (aka Roller Ball)▪Touch surfaces (aka Touch Pads)▪Pointing stick (aka Trak Point)2. Joystick▪Most popular input device for computer games3. Touch Screen▪Monitor with a touch sensitive plastic screen▪Typically used for restaurants, ATM’s and information kiosks4.

What kind of laguages are considered by some people high-level ones?
Assembly Language Assembly language is essentially machine language that has had some of the numbers replaced by somewhat easier to remember mnemonics in an attempt to make it more human-readable. The program that converts assembly language to machine language is called an assembler. While assembly language predates FORTRAN, it is not typically what people think of when they discuss computer languages. Machine Language Machine language consists of the raw numbers that can be directly understood by a particular processor. Each processor's machine language will be different from other processors' machine language. Although called "machine language", it is not usually what people think of when talking about computer languages. Machine language dressed up with mnemonics to make it a bit more human-readable is called assembly language.

5.1 Software Engineering
As with any of the phases, it is important that errors not be allowed to move into subsequent phases. An error in requirements, for example, a misstated function, leads to a faulty design and an implementation that does not do what is required. If this is allowed to proceed undetected, say, until the testing phase, the cost of repairing this error (including redesign and re-implementation) can be substantial.
The first phase, requirements definition, refers to the period during which the requirements of the system desired, that is, its functional characteristics and operational details, are specified. The input to this phase is the stated (often rather loosely stated) needs for the software. Typically, a "requirements document" is the output of this phase, a set of precisely stated properties or constraints that the final product must satisfy. This is not a design, but rather precedes the design, specifying what the system should do without specifying how it is to do it. The existence of a requirements document provides something against which a design (the next phase in the life cycle) can be validated. Sometimes a quickly developed prototype can be a useful vehicle for debugging requirements.
