Software Knowledge

3.1 Data Structures 3.2 Operating System 3.3 Programming Languages 3.4 Software Engineering

3.5 Software Testing and Maintenance

3.2 Operating System • The purpose of an operating system is to provide an environment in which a user may execute programs.• Operating systems exist because they are a reasonable way to solve the problem of creating a usable computing system.• The primary goal of an operating system is convenience for the user.• A secondary goal is efficient operation of the computer system.Resource Management

• The operating system provides the means for the proper use of these resources in the operation of the computer system.• We can view an operating system as a resource allocates.• The operating system sets up the order in which programs are processed, and defines the sequence in which particular jobs are executed

教师: 游彦 计算机专业英语

第3章 Software knowledge

• I/O Management

• To facilitate execution of I/O operations, most operating systems have a standard set of control instructions to handle the processing of all input and output instructions.• These standard instructions, referred to as the input/output control system(IOCS), are an integral part of most operating systems.• The controlling software calls on the IOCS software to actually complete the I/O operation.Classification of Operating Systems

• A single-user operating system expects to deal with one set of input devices—those that can be controlled by one user at a time.• A multi-user operating system is designed to deal with input, output, and processing requests from many users-all at the same time.• A network operating system provides communications and routing services that allow computers to share data, programs and peripheral devices.• A multitasking operating system provides process and memory management services that allow two or more programs to run simultaneously.• All modern operating systems are multitasking and can run several processes simultaneously.教师: 游彦 计算机专业英语

第3章 Software knowledge

• A desktop operating system is one that is designed for a personal computer—either a desktop or notebook computer.•

3.3 Programming Languages • A programming language or computer language is a standardized communication technique for expressing instructions to a computer.• A language enables a programmer to precisely specify what data a computer will act upon, how these data will be stored/transmitted, and what actions to take under various circumstances of cases.• Programming languages are important tools for helping software engineers write better programs faster.Procedural programming and Object-oriented programming • Procedural programming involves using your knowledge of a programming language to create computer memory locations that can hold values and writing a series of steps or operations that manipulate those values.• A single procedural program often contains hundreds of variable and thousands of procedure calls.• Object-oriented programming is an extension of procedural programming in which you take a slightly different approach to writing computer programs.教师: 游彦 计算机专业英语

第3章 Software knowledge

• Writing object-oriented programs involves both creating objects and creating applications that use those objects.Machine Language

• An executable program is a sequence of extremely simple instructions known as machine code.• Machine code instructions are binary—that is, sequences of bits(0s and 1s).• Because these numbers are not understood easily by humans, computer instructions usually are not written in machine code.Assembly Language

• Assembly language uses commands that are easier for programmers to understand than are machine-language commands.• Each machine language instruction has an equivalent command in assembly language.• Assembly language is sometimes inserted into a high-level language program to carry out specific hardware tasks or to speed up a high-level program.High-Level Languages

• If the computer could translate convenient symbols into basic operations, why couldn’t it also perform other clerical coding functions? • A high-level programming language is a means of writing down, in

教师: 游彦 计算机专业英语

第3章 Software knowledge

formal terms, the steps that must be performed to process a given set of data in a uniquely defined way.• The high-level languages are often oriented toward a particular class of processing problems.Compiler and Interpreter

• A complier is a program that translates source code into object code.• Every high-level programming language comes with a compiler.• Because compilers translate source code into object code, which is unique for each type of computer, many compilers are available for the same language.• An interpreter translates high-level instructions into an intermediate form, which it then executes.• The advantage of an interpreter, however, is that it does not need to go through the compilation stage during which machine instructions are generated.•

3.4 Software Engineering • Software engineering is the application of tools, methods, and disciplines to produce and maintain an automated solution to a real-world problem.• Software engineering first emerged as a popular term in the title of

教师: 游彦 计算机专业英语

第3章 Software knowledge

a 1968 NATO conference held in Garmisch, Germany.• A large-scale software projects spans a considerable period of time.A number of distinct phases can be identified over this period of time.Together, these make up what is known as the “software life cycle”.The software life cycle

• Requirements definition: The requirements of the software are established and specified.• Design: A design is developed from an analysis of the requirements.• Implementation: The design is coded in a particular programming language on a particular machine.• Testing: The implemented system is tested to see that it meets the specified requirements.• Operation and maintenance: The system is installed and used.Errors found must be repaired.Requirements definition • The first phase, requirements definition, refers to the period during which the requirements of the system desired, that is, it’s functional characteristics and operational details, are specified.• The input to this phase is the stated(often rather loosely stated)needs for the software.教师: 游彦 计算机专业英语

第3章 Software knowledge

• Typically, a “requirements document” is the output of this phase, a set of precisely stated properties or constraints that the final product must satisfy.• As with any of the phases, it is important that errors not be allowed to move into subsequent phases.Design • The second phase, design, is predominantly creative, while some would argue that creativity is inherent and cannot be trained or improved, it can certainly be enhanced by the use of good procedures and tools.• The input to this phase is a(debugged and validated)requirements document: the output is a design expressed in some appropriate form(for example, pseudo-code).• Each requirement in the requirements document must have a corresponding design fragment to meet it.Implementation • The third phase, implementation, is the actual coding of the design developed in the second phase.• The lure of this phase is strong, and many a foolhardy programmer has been drawn to it before adequately laying the groundwork in the first two phases.• As a result, requirements are incompletely understood and the

教师: 游彦 计算机专业英语

第3章 Software knowledge

design is flawed.• The implementation proceeds blindly, and many problems arise as a result.Testing

• The fourth phase, testing, is concerned with demonstrating the correctness of the implemented program.Inevitably some testing is performed as part of the previous two phases as well.• Any experienced programmer mentally tests each line as it is produced and mentally simulates the execution of any module prior to any formal testing stage.• A “successful” test run means only that no errors were uncovered with the particular circumstances tested;it says nothing about other circumstances.• In theory, the only way that testing can show that a program is correct is if all possible cases are tried(known as an exhaustive test), a situation technically impossible for even the simplest programs.Program maintenance

• The fifth phase is program maintenance phase.Student programmers, unfortunately, rarely become involved in this phase.• Its importance in the real world, however, cannot be overemphasized, since the cost of maintaining a widely used

教师: 游彦 计算机专业英语

第3章 Software knowledge

program can match or exceed the cost of developing it.• Unlike hardware maintenance, software maintenance deals not with repair of deteriorated components, but with repair of design defects, which may include the provision of added functions to meet new needs.教师: 游彦

第四篇：初一英语教案(人教版)Unit1

Unit 1

Hello!

What's

your name?

一、教学目标与要求

通过本单元教学，使学生初步学会“打招呼（Greetings)时所使用的一些简单用语，并要求学生尽可能在交际场合中使用。学生要初步掌握英语字母表中A～N的读音（包括升降两种语调）、书写格式（包括大、小写），并准确认读这些字母。

二、教学重点与难点

1、打招呼用语（Greetings):1)Good morning!2)Hello!3)How are you?Fine,thank you ,And you?

2、句型：1）What's your name? 2)My name is „

3、英语字母A～N。

三、课时安排

本单元共4课时，每课1课时。

重复几遍后，请学生猜一猜是什么意思。之后，叫起一位学生提问： What's your name? 教师在讲这两句英语时，两个句子中的name均要重读，以给学生更深的印象。

在重复上述问题后，如果学生仍不明白，可反复借助手势，先指自己，再指被叫起来的学生说：

T:My name is XXX.What's your name? 这样依次再叫几个学生，每次都重复这一步骤，直到确信学生已能听懂这两句，并能模仿教师语调，用汉语拼音回答出自己的姓名。

3、打开书。先让学生看一下Lesson One中的3张图，教师可对图中人物及对话做些解释，也可请学生描述在图中能看到什么人，这些人在干什么。放录音，学生较熟练之后，可将这两句加到前面的对话中： T:Hello!S:Hello!T:My name is xxx.What's

your

name? S:My

name

is xxx.T:How

are

you,xxx? S:Fine

thank

you/ 重复几次。打开课本，让学生看图。教师可视情况解释图中情景以及讲话的先后顺序，并解释学生称呼高教师为：Miss

Gao.放课文录音。S:Hello!T:How are you,xxx? S:Fine,thank you.找几组同学，到前面来表演相同的对话。在最后一组表演完后，教师留住他们，补充新的内容。即：

S1:How are you? S2:Fine,thank you.And you? S1:I'm fine,too.打开课本，让学生看图，教师解释图中情景。放录音，让学生反复读几遍。将学生分为两组，一组扮演Jim,另一组扮演Li Lei;表演这个对话。之后，分别找出几个同学，进行单独表演。

2、引导学生看图2，然后合上书。教师介绍图中情景。

T：这是某天上午，高老师上完课回到办公室，见到年长的王老师。高老师可以说什么呢？王老师又怎样应答呢？

通过提问，引导学生积极思考，并运用所学过的英语，来回答教师的提问。（这时教师可解释高老师称呼王老师为Mr Wang)学生给出自己的猜测后，教师放录音，三、课堂教学设计

1、复习所学过的对话，参考前两课的步骤与方法，既要有集体操练，又要有个人或小组练习。

2、复习字母A~N的读音。教师每出示一张卡片，说：What's this? 如果学生不懂，可向学生解释，并要求学生用It is(It's„)来回答教师的提问，说出教师手中的字母读音。教师可板书It is(It's„)，讲明It's是It is 的缩写形式。教师不断变换自己手中的字母卡片，反复让学生练习用It's„来回答。集体练习后，可搞小组和个人练习。

3、复习
