1、多媒体应用设计师-专业英语及答案解析(总分：45.00，做题时间：90 分钟)DOM is a platform- and language- (66) API that allows programs and scripts to dynamically access and update the content, structure and style of WWW documents (currently, definitions for HTML and XML documents are part of the specification). The document can be

2、further processed and the results of that processing can be incorporated back into the presented (67) . DOM is a (68) -based API to documents, which requires the whole document to be represented in (69) while processing it. A simpler alternative to DOM is the event-based SAX, which can be used to pr

12、P (71) layer protocols provide services to the application (72) running on a computer. The application layer does not define the application itself, but rather it defines (73) that applications need like the ability to transfer a file in the case of HTTE In short, the application layer provides an (

13、74) between software running on a computer and the network itself. The TCP/IP application layer includes a relatively large number of protocols, with HTTP being only one of those. The TCP/IP (75) layer consists of two main protocol options the Transmission Control Protocol (TCP) and the User Datagra

15、r, what that means, exactly, can be an open-ended question. (71) is a means to capture ideas, relationships, decisions, and requirements in a well-defined notation that can be applied to many different domains. Modeling not only means different things to different people, but also it can use differe

16、nt pieces of UML depending on what you are trying to convey. In general, a UML model is made up of one or more (72) . A diagram graphically represents things, and the relationships between these things. These (73) can be representations of real-world objects, pure software constructs, or a descripti

17、on of the behavior of some other objects. It is common for an individual thing to show up on multiple diagrams; each diagram represents a particular interest, or view, of the thing being modeled. UML 2.0 divides diagrams into two categories: structural diagrams and behavioral diagrams. (74) are u se

18、d to capture the physical organization of the things in your system, i.e., how one object relates to another. (75) focus on the behavior of elements in a system. For example, you can use behavioral diagrams to capture requirements, operations, and internal state changes for elements.（分数：5.00）A.Progr

But false (73) to match the patrons desired date is much more common in our discipline than elsewhere in

22、 engineering. It is very (74) to make a vigorous, plausible, and job risking defense of an estimate that is derived by no quantitative method, supported by little data, and certified chiefly by the hunches of the managers.Clearly two solutions are needed. We need to develop and publicize productivit

23、y figures, bug-incidence figures, estimating rules, and so on. The whole profession can only profit from (75) such data. Until estimating is on a sounder basis, individual managers will need to stiffen their backbones and defend their estimates with the assurance that their poor hunches are better t
