计算机专业英语模拟试题汇总
SQL Server is designed to allow thousands of users to access the database at the same time and is a true client/server database system.
SQL服务器用于允许成千上万的用户同时访问数据库，是一个真正的客户端/服务器端的数据库系统。
An application software is any program designed to perform a specific function directly for the user or, in some cases, for another application program.
应用软件是直接为用户设计的具有专门功能的软件，或在某些情况下，为另一种应用程序设计的软件。
A small network may only connect two computers inside a home to share a single printer and Internet connection.
一个小型的网络可能是连结一个家庭中的两个计算机，共同分享一个打印机和Internet连结。
There is free firewall software available that can run on your computer and provide a good level of protection to your network.
有一些免费的防火墙软件能在你的计算机上运行，并且给你的网络提供很好的保护。
For developing a software product, the development process is divided into 5 stages: Requirements Analysis & Specification, Design, Coding, Testing, and Maintenance.
开发一个软件产品，开发过程分为五个步骤：需求分析和说明，设计，写代码，测试和维护。
EDI refers to the electronic exchange of business information between two companies using a specific and structured format over private networks.
EDI指的是两个公司之间通过私有网络使用特定、结构化的格式电子交换商业信息。
Some applications, such as Word, allow for several windows in a special mode called MDI in which you can open multiple documents within the same application.
一些应用软件，例如word，允许几个窗口同时在一个叫做MDI的模式下存在，你能够在一个软件中打开多个文档。
Functional testing tests whether the output is the expected result with the valid input.
功能测试检验的事用有效的输入是否能够得到所期望的输出。
A database management system (DBMS) defines, creates, and maintains a database, The DBMS also allows controlled access to data in the database.
数据库管理系统定义、创建和维护数据库。数据库管理系统也允许对数据库中的数据进行受控的访问。
Programming languages, in computer science, are the artificial languages used to write a sequence of instructions ( a computer program ) that can be run by a computer.
在计算机科学中，编程语言是用于编写可由计算机运行的一系列指令（计算机程序）的人工语言。
High-level languages are relatively sophisticated sets of statements utilizing words and syntax from human language.
高级语言是相对复杂的一系列语句，它们使用来自人类语言的词汇和句法。
Passwords are secret words or numbers that must be keyed into a computer system to gain access. 口令是秘密的单词或数字，人们必须将其键入一个计算机系统才能对该系统进行访问。
A high-level language is an artificial language with which we can write various instructions. This is possible not because computer processors are now so technologically advanced that they can “understand”these languages, You should translate from programming languages into machine language which can be understood by the computer processors. Compilers can accomplish this task. This does mean that a high-level language program is not directly executable: it must be compiled to produce processor program, which is executable.
高级语言是一种人造语言，使用它我们可以写不同的指令。这成为可能不是因为计算机处理器技术先进到它们可以理解这些语言。你需要讲这些语言翻译成计算机处理器能够理解的机器语言。编译器能够完成这项工作。这就意味着高级语言程序不是直接可执行的：它必须被编译生成处理器程序，这些程序是可执行的。
SQL Server is a RDBMS (Relational Database Management System) made by Microsoft. This means that the data is stored in two dimensional tables, RDBMS all have tables called catalogs or dictionaries that contain information about the particular databases. Don’t worry if that doesn’t make sense. I like to think of SQL Server as the big brother to Microsoft Access. SQL Server is designed to allow thousands of users to access the database at the same time and is a true client/server database system. It is much more secure than Access, Rights can be assigned to individual users and administrators, For example you can setup one user that can only insert data in the database but cannot delete any.
SQL Server是微软的关系数据库管理系统。它的数据存储在二维表格中。关系数据库管理系统包含叫做目录或字典的表格，记录特定数据库的信息，如果不能理解也没有观看。我喜欢将SQL Server看作Access的哥哥。SQL Server允许数以千计的用户同时访问数据库，它是一个真正的C/S数据库系统，比Access更安全。权限可以分配给个人用户或管理者，比如，你可以建立一个用户，他能插入数据到数据库中，却不能删除数据。
Programming languages can be classified as either low-level languages or high-level languages. Low-level programming languages, or machine languages, are the most basic type of programming languages and can be understood directly by a computer. Machine languages differ depending on the manufacturer and model of computer. High-level languages are programming languages that must first be translated into a machine language before they can be understood and processed by a computer. Examples of high-level languages are C, C++, PASCAL, and FORTRAN. Assembly languages are intermediate languages that are very close to machine languages and do not have the level of linguistic sophistication exhibited by other high-level languages, but must still be translated into machine language.
编程语言可以分为高级语言和低级语言。低级语言，或者说机器语言，是最贴近计算机的语言，机器语言随着计算机制造商河计算机模型的不同而不同。高级语言是在由计算机处理前必须首先翻译成机器语言的编程语言。高级语言的例子有C, C++, PASCAL和FORTRAN。
汇编语言是非常接近机器语言的中间语言，没有其他高级语言的复杂语法，但仍需要翻译成机器语言。

计算机网络基础知识总结 1. 网络层次划分 2. OSI七层网络模型 3. IP地址 4. 子网掩码及网络划分 5. ARP/RARP协议 6. 路由选择协议 7. TCP/IP协议 8. UDP协议 9. DNS协议 10. NAT协议 11. DHCP协议 12. HTTP协议 13. 一个举例 计算机网络学习的核心内容就是网络协议的学习。网络协议是为计算机网络中进行数据交换而建立的规则、标准或者说是约定的集合。因为不同用户的数据终端可能采取的字符集是不同的，两者需要进行通信，必须要在一定的标准上进行。一个很形象地比喻就是我们的语言，我们大天朝地广人多，地方性语言也非常丰富，而且方言之间差距巨大。A地区的方言可能B地区的人根本无法接受，所以我们要为全国人名进行沟通建立一个语言标准，这就是我们的普通话的作用。同样，放眼全球，我们与外国友人沟通的标准语言是英语，所以我们才要苦逼的学习英语。 计算机网络协议同我们的语言一样，多种多样。而ARPA公司与1977年到1979年推出了一种名为ARPANET的网络协议受到了广泛的热捧，其中最主要的原因就是它推出了人尽皆知的TCP/IP标准网络协议。目前TCP/IP协议已经成为Internet中的“通用语言”，下图为不同计算机群之间利用TCP/IP进行通信的示意图。 1. 网络层次划分
为了使不同计算机厂家生产的计算机能够相互通信，以便在更大的范围内建立计算机网络，国际标准化组织（ISO）在1978年提出了“开放系统互联参考模型”，即著名的OSI/RM模型（Open System Interconnection/Reference Model）。它将计算机网络体系结构的通信协议划分为七层，自下而上依次为：物理层（Physics Layer）、数据链路层（Data Link Layer）、网络层（Network Layer）、传输层（Transport Layer）、会话层（Session Layer）、表示层（Presentation Layer）、应用层（Application Layer）。其中第四层完成数据传送服务，上面三层面向用户。 除了标准的OSI七层模型以外，常见的网络层次划分还有TCP/IP四层协议以及TCP/IP五层协议，它们之间的对应关系如下图所示： 2. OSI七层网络模型 TCP/IP协议毫无疑问是互联网的基础协议，没有它就根本不可能上网，任何和互联网有关的操作都离不开TCP/IP协议。不管是OSI七层模型还是TCP/IP 的四层、五层模型，每一层中都要自己的专属协议，完成自己相应的工作以及与上下层级之间进行沟通。由于OSI七层模型为网络的标准层次划分，所以我们以OSI七层模型为例从下向上进行一一介绍。
