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.
wireless networks. You can either install software
firewalls on each computer, or install a hardware
firewall on your entire network.

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.

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.
计算机英语 机工版 第3版 第五单元翻译
第五单元:软件过程课文A:软件过程模型一、引言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。
一个软件过程模型是对一个软件过程的一种抽象表示。
每个过程模型都从一个特定角度表示一个过程,因此都只提供有关那个过程的部分信息。
本文介绍几种非常通用的过程模型(有时称为过程范例),并从体系结构的角度描述它们。
也就是说,我们看到的是过程的框架,而非具体活动的细节。
这些类属模型不是对软件过程的规定性描述。
确切点说,它们是过程的抽象,可用于解释软件开发的不同方法。
你可以将其视为可扩展和调整以创建更为具体软件工程过程的过程框架。
这里论述的过程模型是瀑布模型、演化开发和基于组件的软件工程。
这3种类属过程模型在当前的软件工程实践中广泛使用。
它们不是互不相容,而是经常一起使用,尤其是在大型系统开发的情况下。
一个较大型系统内的子系统可使用不同的方法开发。
因此,尽管分别讨论这些模型比较方便,但应该明白,实际上它们经常结合使用。
二、瀑布模型最早公布的软件开发过程模型源自比较通用的系统工程过程。
这种模型如图5A-1所示。
由于从一个阶段到另一个阶段的瀑布状级联,该模型称为瀑布模型或软件生命周期。
该模型的主要阶段映射基本的开发活动:1、需求分析与定义。
系统的服务、约束和目标要经过与系统用户的磋商加以确定。
然后,它们得到详细定义并作为系统规格说明。
2、系统与软件设计。
系统设计过程将需求划分成需硬件或软件系统实现的部分。
该过程确立一个总的系统体系结构。
软件设计涉及到确定和描述基本的软件系统抽象及其相互关系。
3、实现与单元测试。
在这个阶段,软件设计被实现为一组程序或程序单元。
单元测试涉及到验证每个单元是否符合其规格说明。
4、集成与系统测试。
单个的程序单元或程序进行集成并作为一个完整系统进行测试,以确保软件需求已得到满足。
