Para one：
Computer security is the process of preventing and detecting unauthorized use of your computer. Prevention measures help you to stop unauthorized users (also known as “intruders”) from accessing any part of your computer system. An effective network security strategy requires identifying threats and then choosing the most effective set of tools to combat them.

Crossword Puzzle Answers:Open Ended Questions:1.Describe system software. What are the four types of system programs?System software works with end users, application software, and computer hardware to handlethe majority of technical details. System software is not a single program. Rather it is a collection or a system of programs that handle hundreds of technical details with little or no userintervention. System software consists of four types of programs:• Operating systems coordina te computer resources, provide an interface between users and the computer, and run applications.• Utilities, also known as service programs, perform specific tasks related to managing computerresources.• Device drivers are specialized programs that all ow particular input or output devices tocommunicate with the rest of the computer system.• Language translators convert the programming instructions written by programmers into a language that computers understand and process.2.What are the basic functions of every operating system? What are the three basic operatingsystem categories?Every operating system performs various functions. These functions are:• Managing resources:These programs coordinate all the computer’s resources includingmemory, processing, storage, and devices such as printers and monitors. They also monitorsystem performance, schedule jobs, provide security, and start up the computer.• Providing user interface: Users interact with application programs and computer hardware through a user interface.• Running applications: These programs load and run applications such as word processors and spreadsheets. Most operating systems support multitasking, or the ability to switch between different applications stored in memory.The three main categories of Operating systems are:• Embedded operating systems - The entire operating system is stored within or embedded in the device and permanently stored on ROM.• Network operating systems (NOS) are used to control and coordinate computers that are networked or linked together.• Stand-alone operating systems control a single desktop or notebook computer.3.Explain the differences and similarities betw een Windows, Mac OS, and Linux.They all perform the basic functions of an operating system. They manage resources, provide a user interface, and run applications. They all use a graphical user interface, and can network small groups of computers.The differences are as follows:Windows– has 90 percent of the market operating system market share, more applicationprograms are developed to run under Windows than any other operating system, designed to run with Intel and Intel-compatible microprocessors. The new version, Vista, has Advanced system security, a Three-dimensional workspace, and utilizes WinFS, makes it possible to locate files based on a description of their content.MAC OS- Designed to run on Apple machines, but with the latest version can also run on Intel microprocessors. It is not as widely used as Windows, but is one of the most innovativeoperating systems. It includes utilities such as Spotlight which is an advanced search tool that can rapidly locate files, folders, email messages, addresses, and much more, and Dashboard Widgets which are a collection of specialized programs that will constantly update and display information.Linux– Of the three operating systems, it is the only one that is an open source. It is a version of UNIX. It runs on powerful microcomputers and by servers on the Web. It encourages others to modify and further develop the code.4.Discuss utilities. What are the five most essential utilities? What is a utility suite?Utilities are specialized programs designed to make computing easier. The most essential are • Troubleshooting or diagnostic programs that recognize and correct problems, ideally before they become serious.• Antivirus programs that guard your computer system against viruses or other damagingprograms that can invade your computer system.• Uninstall programs that allow you to safely and completely remove unneeded programs and related files from your hard disk.• Backup programs that make copies of files to be used in case the originals are lost or damaged.• File compression programs that reduce the size of files so they require less storage space and can be sent more efficiently over the Internet.Utility suites combine several programs into one package. Buying the package is less expensive than buying the programs separately.5.Explain the role of device drivers. Discuss the Add Printer Wizard and WindowsUpdate.Every device, such as a mouse or printer, that is connected to a computer system has a special program associated with it. This program, called a device driver, works with the operating system to allow communication between the device and the rest of thecomputer system. Each time the computer system is started, the operating system loads all of the device drivers into memory.Windows’ Add Printer Wizard provides step-by-step guidance for selecting theappropriate printer driver and installing that driver.Windows Update makes it easy to update the drivers on your computer.1.Writing About Technology exercise #1 Antitrust has students research and write aboutthe legal and ethical ramifications of Microsoft’s antitrust lawsuit and domination of the software market.Web Tools1.Expanding Your Knowledge exercise #3 Customized Desktop has students explore theWeb to learn about desktop customization.

Computer English Unit 5 Software Process(计算机英语 第五单元 软件过程)
Unit 5 Software Process第五单元：软件过程Section A Software Process Models课文A：软件过程模型Ⅰ.Introduction一、引言A software process is a set of activities that leads to the production of a software product. 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.一个软件过程是生产出软件产品的一系列活动。
这些活动可能涉及使用一种像Java或C这样的标准编程语言从零开始开发软件。
然而，开发新软件越来越多地使用的方法是，扩展和修改现有系统，以及配置和集成现成软件或系统组件。
A software process model is an abstract representation of a software process. Each process model represents a process from a particular perspective, and thus provides only partial information about that process. This section introduces a number of very general process models (sometimes called process paradigms) and presents them from an architectural perspective. That is，we see the framework of the process but not the details of specific activities.一个软件过程模型是对一个软件过程的一种抽象表示。
