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(简略的、缩写) PnP, is a catchy(动人的、易记住的) phrase( [freiz] 短语、习语) used to describe devices(设备、装备) that work with a computer system as soon as(与……一样)they are connected(链接的、有关系的). The user does not have to manually(手动的、用手) install drivers(驱动) for the device(装置、策略) or even tell the computer that a new device has been added. Instead the computer automatically(自动的、机械的) recognizes the device, loads new drivers for the hardware if needed, and begins to work with the newly connected device(链接设备),即插即用,缩写为PnP,这是一个容易记住的短语,它用来描述与计算机操作系统连接工作有关的设备。

用户不需要为设备手动安装驱动,甚至于不需要告诉计算机已经添加了饿一个新的设备。

计算机自动识别设备,如果需要为硬件加载一个新的驱动,并且开始工作在新的连接设备上。

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(拥塞的、接通电源) 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.例如,如果你在你的电脑上的USB接口连接了一个即插即用的鼠标,它开始工作时接通电源只需要几秒钟。

计算机专业英语大作业Patterns Instruction in Software EngineeringAbstract:The paper deals with a training system with a client-server architecture created for students who are learning to design and implement object-oriented software systems with reusable components, and also targeting those users who wish become accustomed with (or improve their skills related to) software design.The paper briefly presents the design patterns which are to be found in the software library, as well as the manner of applying them.The user of such a system has five types of patterns at his/her disposal (Factory Method, Builder, Command, Mediator, Observer), out of which will be able to chose one/more than one, depending on the requirements of the system proposed for design.1.IntroductionMotto: “The software design patterns help you learn more from other people’s successes than from your own failures”[Mark Johnson] .A software system is a dynamic entity that undergoes multiple changes during its life-cycle, under the influence of factors such as: new user requirements, adding new functionalities, environment adjustment, etc.Therefore, apart from fulfilling those functions which it was designed to fulfill, a software application must be easily changeable, with some of its modules eventually re-used.Having this goal, the application must fulfill certain requirements regarding robustness, mobility, flexibility, scalability, etc.The software design principles are regarded as ways of obtaining the right and re-usable design.By applying abstractization and OOP languages polymorphic techniques, the open-shut principle and the substitution principle (Liskov) upon classes of problems, common solutions were reached –solutions which make up the so-called design patterns.The software patterns facilitate re-using design and architecture.If the design and/orarchitecture of a system were built with design patterns (techniques which have proven efficient), then they will be more accessible and easier to understand by those software developers who build new systems based on old design.The patterns help the software specialist chose that design that makes the system re-usable.In software engineering, “design pattern”(DP) means a solution applicable to a certain type of problems.A design pattern is a description model of how a problem should be solved.A pattern cannot be directly transformed in source code.The purpose of design patterns is to enable a “good”object-oriented design, and more than that –to make it reusable (which is more important than reusing the code, regardless of the fact that reusing the design often implies reusing the code).The quality of software design is proportional to the experience and previous knowledge of the one performing it.An expert applies solutions previously used and proven efficient for similar problems.When the expert finds a solution considered acceptable, he/she uses it again.Design patterns solve specific design problems, making the OO more flexible, elegant and reusable.DP help beginners with software design, proposing patterns based on previous experience.A user who is familiar with the DP-s can apply them instantly in order to solve specific problems, without having to rediscover them.By using the software design patterns while designing an object-oriented architecture, one is guaranteed to obtain system compliance to software engineering principles, while also preserving the qualities of “good design”: reusable, flexible, robust .2.Design PatternsDepending on the DP purpose, the authors of GoF [4] proposed three main categories of patterns: creational patterns, structural patterns and behavioral patterns.These are the most well-known DP, but not the only ones.Other types of patterns emerged –more or less popular –as well as variations of the GoF patterns.A pattern has four essential components:: the name of the DP must describe in a few words a design pattern problem, its solutions and the solution’s effects.2.Problem: describes the situations when the pattern is applicable, explaining the problem as well as its context.3.Solution: describes the components of the design, the relationships between them, the responsibilities of each component and the way they interact.The solution does not describe a specific design for a certain situation or a correct implementation, because a pattern has a general character, referring to a plethora of contexts.The DP presents an abstract description of a problem and a general arrangement of the components (classes and objects) that solve the described problem.4.Effects: refer to the results of applying the pattern, which are very important when we evaluate the alternatives and we estimate the costs and benefits of applying the pattern.The effects of a pattern are also to be perceived in the flexibility, extensibility and portability of a system.DP identifies the classes and instances which participate, their role, collaboration and responsibility sharing between them.The design patterns that the user of the proposed system has at hand are: Factory Method and Builder (from the Creational Patterns category), Command, Mediator and Observer, (from the Behavioral Patterns category).3.The Architecture of the SystemThe platform is designed as a distributed application, providing the option of distance learning/tutoring by means of a computer network or the Internet.The application can be classified as having “three - tier" architecture, the Client part being represented by the configuration module and the tutoring material presentation module.The user connects to the system by means of a Login module, monitored by an Administrator agent (CerberusAgent).After authentication the user may have access to a configuring instrument (if the user connected to the system is the tutor) or to the user interface by means of which the learning material will be presented (if the user is a student).This part of the application will be monitored by an interface agent (InterfaceAgent).The application server contains the agent platform that monitors the student activity, and a web server responsible for delivering the learning material to the user interface (Apache Tomcat).The third level consists of a xml database (Apache Xindice), which stores information about the structure of the course, student models, etc.The MTS training system is designed for students which learn to design and implement object-oriented software systems, with re-usable components, but also for those users who wish to become familiar with (or improve) software design.We present the approach of a multi-agent intelligent platform for tutoring student which provides a Student Model.The “modeling student process”used the overlay architecture (common for many tutoring systems) combined with the Bayesian Theory of Probability .The system’s tasks are distributed among the intelligent agents (software agents), each having clearly specified individual roles as following: administrator (Cerberus Agent); interface (InterfaceAgent); tutor (Tutor Agent); student (Student Agent).Moreover, the system has “three-tier”architecture and was implemented in Java language.We may well imagine software agents attached to every application or tutoring environment, each having an explicit representation of the users’objectives, of their plans and resources.These agents communicate and negotiate with each other in order to fulfill their individual or group objectives.The multi-agent tutoring system (MTS) was designed and implemented within the Computer Science Department, in which research focused upon “modeling”the student with a view to identifying the most suitable methods and tutoring strategies by taking into account individual knowledge and abilities.The user of this kind of system has all five types of previously described patterns at his/her disposal (Factory Method, Builder, Command, Mediator, Observer), out ofwhich will be able to use one or more, depending on the requirements of the system that needs to be designed.Depending on the needs of the user that must fulfill the requirements of the system, one selects from Tutor Agent the design patterns best suited for those functions.The patterns help build the menus of the application and the user interface.Then the database is built, as the user has permanent access to an example of application as similar as possible to the one which needs to be carried out.In order to develop an application, the student must know the Java programming language, must be familiar with MySql data servers and must be able to use the Eclipse platform.The Eclipse platform is an open source framework from IBM which aims to provide a variety of basic services for software developers [6].4.ConclusionsThe system wishes to be a useful working instrument for software application development training, for both students and other types of users.A design pattern together with an example of using that pattern may become a way of working in software design.Moreover, in this case applying design patterns –therefore design principles - in carrying out an object-oriented application results into a reusable design and reusable modules / components.Also, the resulting code enjoys more robustness and flexibility, these two characteristics being essential for developing new modules that would add new functionalities and operations to the application; the design/code of the application is open to extension and closed for changes, according to OCP.Another important aspect relates to the maintenance activities which the designed application will undergo along its life-cycle: they will more cost effective, as no change will disseminate through the entire system, the application code being built so that it isolates the volatile classes (according to the principle of reversing dependencies), the dependencies being in the way”details depend upon abstractization”and not the other way around.The software patterns ensurecompliance to design principles, as they contribute to obtaining a steady and efficient system, and they provide design discipline for st but not least, using such a system in software engineering learning makes the process much more attractive and efficient.The design patterns approach in software engineering training fits the pedagogical Schemas Theory (created by Bartlett at the beginning of the 20th century) .A brief representation of the particular knowledge of the training domain can help the trainee to easier absorb the new information, while the organization and structuring of the knowledge as patterns will guide him/her in finding (remembering) the necessary information in a certain context.We believe that within such an approach one can create a training ontology from Software Engineering.软件工程模式教学摘要:本页处理一种C/S架构旳训练系统, 为学习设计和实行一种面向对象旳用可重用组件旳软件系统旳学生而设计, 也将目旳瞄准那些顾客谁但愿成为(或提高他们旳有关技能)软件设计习惯。

The faster the processor, the faster execution speed of the computer would be, so, let us revisit. Hard drive, like a basement, it can store the information you need.

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.即插即用,有时缩写为PnP的,是用来只要它们连接来形容,随着计算机系统正常工作的设备一个朗朗上口的短语。
