单项选择题 A Web browser is simply a terminal emulator, designed to display text on a screen. The two essential differences between an ordinary terminal emulator and a Web browser are that the browser knows how to deal with 1 , and that it has a mechanism for 2 graphical files. Display text, display graphics, and 3 hyperlinks-there's 99 percent of the 4 value. That's not to say that the manufacturers didn't go all-out to attach a hyperactive efflorescence of useless capabilities onto their browsers. Remember when media channels in the browser were a big deal, instead of the clutter you can't wait to delete from your favorites of bookmarks menu? Remember when client-side Java applets were supposed to become the preferred 5 for application development? Remember frames and all their nasty side effects?

6 data effectively is crucial for success in today's competitive environment. Managers must know how to use a variety of tools. Integrated data takes information from different sources and puts it together in a meaningful and useful way. One of the difficulties of this is the 7 in hardware and software. 8 integration uses a base document that contains copies of other objects. 9 integration uses a base document that contains the current or most recent version of the source document it contains. 10 provides an overview of the program written in "plain" English, without the computer syntax.

Most computer systems are 11 to two different groups of attacks: Insider attacks and outsider attacks. A system that is known to be 12 to an outsider attack by preventing. 13 from outside can still be vulnerable to the insider attacks accomplished by abusive usage of 14 users. Detecting such abusive usage as well as attacks by outsides not only provides information on damage assessment, but also helps to prevent future attacks. These attacks are usually 15 by tools referred to as Intrusion Detection Systems.

MIDI enables people to use 16 computers and electronic musical instruments. There are actually three components to M1DI, the communications " 17 ", the Hardware Interface and a distribution 18 called "Standard MIDI Files". In the context of the WWW, the most interesting component is the 19 Format. In principle, MIDI files contain sequences of MIDI Protocol messages. However, when MIDI Protocol 20 are stored in MID! files, the events are also time-stamped for playback in the proper sequence. Music delivered by MIDI files is the most common use of MIDI today.

Certificates are 21 documents attesting to the 22 of a public key to an individual or other entity. They allow verification of the claim that a given public key does in fact belong to a given individual. Certificates help prevent someone from using a phony key to 23 someone else. In their simplest form, Certificates contain a public key and a name. As commonly used, a certificate also contains an 24 date, the name, of the CA that issued the certificate, a serial number, and perhaps other information. Most importantly, it contains the digital 25 of the certificate issuer. The most widely accepted format for certificates is X.509, thus, Certificates can be read or written by any application complying with X.509.

It should go without saying that the focus of UML is modeling. However, what that means, exactly, can be an open-ended question. 26 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 different pieces of UML depending on what you are trying to convey. In general, a UML model is made up of one or more 27 . A diagram graphically represents things, and the relationships between these things. These 28 can be representations of real-world objects, pure software constructs, or a description 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. 29 are used to capture the physical organization of the things in your system, i. e. , how one object relates to another. 30 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.

DOM is a platform and language- 31 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 further processed and the results of that processing can be incorporated back into the presented 32 . DOM is a 33 -based API to documents, which requires the whole document to be represented in 34 while processing it. A simpler alternative to DOM is the event-based SAX, which can be used to process very large 35 documents that do not fit info the memory available for processing.

The Rational Unified Process (RUP) is a software engineering process, which captures many of best practices in modern software development. The notions of 36 and scenarios have been proven to be an excellent way to capture function requirements. RUP can be described in two dimensions - time and content. In the time dimension, the software lifecycle is broken into cycles. Each cycle is divided into four consecutive 37 which is concluded with a well-defined 38 and can be further broken down into 39 - a complete development loop resulting in a release of an executable product, a subset of the final product under development, which grows incrementally to become the final system. The content structure refers to the disciplines, which group 40 logically by nature.
