● Although a given waveform. may contain frequencies over a very broad range, as a practical matter any transmission system will be able to accommodate only a limited band of (71) . This, in turn, limits the data rate that can be carried on the transmission (72) . Asquare wave has an infinite number of frequency components and hence an infinite (73) . However, the peak amplitude of the kth frequency component, kf, is only 1/k, so most of the (74) in this waveform. is in the first few frequency components. In general, any digital waveform. will have (75) bandwidth. If we attempt to transmit this waveform. as a signal over any medium, the transmission system will limit the bandwidth that can be transmitted.(71)A. frequencies B. connections C. diagrams D. resources(72)A. procedure B. function C. route D. medium(73)A. source B. bandwidth C. energy D. cost(74)A. frequency B. energy C. amplitude D. phase(75)A. small B. limited C. infinite D. finite(71)A. frequenciesB. connectionsC. diagramsD. resources(72)A. procedureB. functionC. routeD. medium(73)A. sourceB. bandwidthC. energyD. cost(74)A. frequencyB. energyC. amplitudeD. phase(75)A. smallB. limitedC. infiniteD. finite

Originally, the World-Wide Web was designed as information medium for (71) research teams. A deliberately simple implementation model was chosen to make it as simple as possible for authors to (72) documents to the web, and to (73) these in the sense of updating content. This implementation model is centered around the notion of resources, usually file-base D. For the (74) intended use of the web, resources presented a useful abstraction, as they related to relatively self-contained chunks of information such as research publications and (75) pages. Such chunks of information typically could be set up and maintained independently of other resources, so that resources were the appropriate abstraction for composition and modification.A.allB.worldC.distributedD.internet
● Spyware and other forms of malware are the biggest online threat to your computer's (71) nowadays. These malicious (72)which get to your PC through freeware, shareware, commercial sites, deceptive pop-ups or in any other way, can record your surfing habits and sites you visit, share your personal information with their partners. Any personal (73), when inwrong hands, can leave you a victim of an "identity theft" by steeling your credit (74)details,birth records and other (75) information.
XML is a(71)language for documents containing(72)information.Structured information contains both content(words, pictures, etc.)and some indication of what role that content plays(for example, content in a section heading has a different meaning from content in a footnote, which means something different than content in a figure caption or content in a database table, etc.). Almost all documents have some structure.A markup language is a(73)to(74)structures in a document. The XML specification defines a standard way to add markup to(75).A.make-upB.madeupC.markupD.makeup
