2、e projects has little to do with technology and tools, and much to do with lack of processU U 3 /U /U. Experience has shown that introducing new technology and tools in an immature or undisciplined environment is likely to increase the chaos. CASE tools are not enough. “A fool with a tool is still a

This chapter explains some of the uses and benefits

7、of Activity Based Costing. We use IDEFOU U 8 /U /Umodeling in conjunction with ABC to enable more effective businessU U 9 /U /Udesign decisions.In order to achieve the major goals of business process improvement, process simplification and improvement, FAA managers need to fully understand the cost,

10、L-like query language for the Web is the absence of a databaseU U 11 /U /Ufor this huge, heterogeneous repository of information. However, if we are interested in HTML documents only, we can construct a virtual schema from the implicit structure of these files. Thus, at the highest level ofU U 12 /U

11、 /U, every such document is identified by its Uniform Resource Locator (URL), and aU U 13 /U /Uand a text. Also, Web severs provide some additional information such as the type, length, and the last modification date of a document. So for data mining purposes, we can consider the set of all HTML doc

12、uments as a relation:Document (url, title, text, type, length, modif)Where all theU U 14 /U /Uare character strings. In this framework, an individual document is identified with aU U 15 /U /Uin this relation. Of course, if some optional information is missing from the HTML document, the associate fi

A. relation B. field C. script D. tuple（分数：1.00）A.B.C.D.When the system upon which a transport entity is running fails and subsequently restarts, theU U 16 /U /Uinformation of all active connections is lost. The affected connections become half-open,

15、as the side that did not fail does not yet realize the problem.The still active side of a half-open connections can close the connection using aU U 17 /U /Utimer. This timer measures the time the transport machine will continue to await anU U 18 /U /Uof a transmitted segment after the segment has be

16、en retransmitted the maximum number of times.0When the timerU U 19 /U /U, the transport entity assumes that either the other transport entity or the intervening network has failed. As a result, the timer closes the connection, and signals an abnormal close to the TS user.In the event that a transpor

17、t entity fails and quickly restarts, half-open connections can be terminated more quickly by the use of the RST segment, the failed side returns an RST i to every segment i that it receives, when the RST i reaches the other side, it must be checked for validity based on theU U 20 /U /Unumber i, as t

18、he RST could be in response to an old segment, if the reset is valid, the transport entity performs an abnormal termination.（分数：5.00）(1). A. data B. state C. signal D. control（分数：1.00）A.B.C.D.(2).

20、ations network is costU U 21 /U /U. For example, the maintenance of multiple networks can require additional staff. Often, this staff must be trained on multiple vendor technologies, sometimes requiring parallel groups specializing in eachU U 22 /U /U. Hence, additional maintenance procedures must b

21、e maintained and administrative records areU U 23 /U /U. The duplication of transport facilities to carryU U 24 /U /Unetwork traffic is an inefficient use of resources. And not surprisingly, more technologies installed in a central office means the necessity for more physical space, and an increase

22、in power connections and power consumption. Migration of theseU U 25 /U /Unetwork elements to IP-based DCNs is alogical strategy.（分数：5.00）(1).

32、then easily transformed into proper XML. SOX was created because developers can spend a great deal of time with raw XML. For many of us, the popular XML U U 38 /U /Uhave not reached a point where their tree views, tables and forms can completely substitute for the underlying.U U 39 /U /Ulanguage. Th

33、is is not surprising when one considers that developers still use a text view, albeit enhanced, for editing other languages such as JavA. SOX usesU U 40 /U /Uto represent the structure of an XML document, which eliminates the need for closing tags and a number of quoting devices. The result is surpr

36、ed in the transactions. This has led to an industry-wide quest for better, more secure methods for controlling IT operations, and for deploying strong security mechanisms deeply and broadly throughout networked infrastructures and client devices. One of the more successful concepts to engage the ima

37、ginations of the security community has been the development of standards-based securityU U 44 /U /Uthat can be incorporated in the hardware design of client computers. The principle of encapsulating core security capabilities inU U 45 /U /Uand integrating security provisions at the deepest levels o

40、hat were not possible, or not cost-effective, in the past. For example, WLAN-based applications can enable fine-grained management of supply and distributionU U 46 /U /Uto improve their efficienty and reduceU U 47 /U /U. WLANs can also enable entirely new business processes. To cite but one example,

41、 hospitals are using WLAN-enabled point-of-care applications to reduce errors and improve overallU U 48 /U /Ucare. WLAN management solutions provide a variety of other benefits that can be substantial but difficult to measure. For example, they can protect corporate data by preventingU U 49 /U /Uthr

42、ough rogue access points. They help control salary costs, by allowing IT staffs to manage larger networks without adding staff. And they can improve overall network mananement by integrating with customers existing systems, such as OpenView and UniCenter. Fortunately, it isnt necessary to measure th

43、ese benefits to justify investing in WLAN management solutions, which can quickly pay for themselves simply by minimizing time-consumingU U 50 /U /Uand administrative chores.（分数：5.00）(1).

These users may connect to the network through wired ports in conference rooms or offices, or via wireless access points. In allowing this open access for third parties, LANs becomeU U 51 /U

46、 /U. Third parties can introduce risk in a variety of ways from connecting with an infected laptop to unauthorized access of network resources toU U 52 /U /Uactivity. For many organizations,however, the operational complexity and costs to ensure safe third party network access have been prohibitive. Fifty
