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 case
2、s, 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 yo
3、ur 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
4、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 c

8、ecret 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 th
9、at 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
10、 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 s
11、tored 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 u

14、s. 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 tra
15、nslated 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 ex
16、hibited 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 。名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 2 页，共 3 页 - - - - - - - - - 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。名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 3 页，共 3 页 - - - - - - - - -
