1、 ASP 外文翻译 +原文 xinxiasd 1 ASP外文翻译 +原文 ENGLISHE： Develop Web application program using ASP the architecture that must first establish Web application. Now in application frequently with to have two: The architecture of C/S and the architecture of B/S. Client/server and customer end / server hold the a

2、rchitecture of C/S. The customer / server structure of two floor. Customer / server ( Client/Server ) model is a kind of good software architecture, it is the one of best application pattern of network. From technology, see that it is a logic concept, denote will a application many tasks of decompos

3、ing difference carry out , common completion is entire to apply the function of task. On each network main computer of web site, resource ( hardware, software and data ) divide into step, is not balanced, under customer / server structure, without the client computer of resource through sending requ

4、est to the server that has resource , get resource request, so meet the resource distribution in network not balancedness. With this kind of structure, can synthesize various computers to cooperate with work, let it each can, realize the scale for the system of computer optimization ( Rightsizing )

5、with scale reduce to melt ( Downsizing ). Picture is as follows: It is most of to divide into computer network application into two, in which the resource and function that part supports many users to share , it is realized by server； Another part faces every user , is realized by client computer, a

6、lso namely, client computer is usual to carry out proscenium function , realizes man-machine interaction through user interface , or is the application program of specific conducted user. And server usually carries out the function of backstage supporter , manages the outside request concerning seti

7、ng up, accepting and replying user that shared. For a computer, it can have double function , is being certain and momentary to carve to act as server , and again becomes client computer in another time. Customer / server type computer divide into two kinds, one side who offers service is called as

8、server , asks one side of service to be called as customer. To be able to offer service, server one side must have certain hardware and corresponding server software； Also, customer one side must ASP 外文翻译 +原文 xinxiasd 2 also have certain hardware and corresponding customer software. There must be a

9、agreement between server and customer, both sides communicate according to this agreement. Apply customer / server model in Internet service , the relation between customer and server is not immutable. Some Internet node offers service on the one hand , also gets service on the other hand from other

10、 node； It is even in one time dialogue course, mutual role also exchanges probably. As in carry out file transmission , if be called as one side who offers file server, is called as one side who gets file customer, when using get or mget order since another node takes file, can think that what self

11、use and it is client computer , is using put or mput order to another node dispatch file can again think the machine that used self is server. Multilayer customer / server structure Along with the development of enterprise application, recently, have again arisen a kind of new multilayer architectur

12、e, it applies customer end to divide into two minutes: Customer application and server apply. Customer application is the part of original customer application , is another and partial to have been transfered to server to apply. New customer application takes the responsibility for user interface an

13、d simple regular business logic and new server application resident core , changeable business logic. Therefore its structure has become new ( Client application + Server application )/Server structure. Following picture shows: This kind of structure has solved traditional Client/Server can expand p

14、roblem, have reduced customer end business logic , and have reduced the requirement of customer end for hardware. At the same time because of a lot of business logic concentrations have gone to unitary application server on, the maintenance work of application system had been also concentrated together, have eliminated the problem in the traditional structure of Client/Server that software distributes. This kind of structure is called as the architecture of B/S. Browser/Server and browser / server hold the architecture of B/S. On
