A TCP (72) accepts user data streams from local process, breaks them into pieces not exceeding 64KB, and sends each piece as a separate IP (73). When datagrams containing TCP data arrive at a machine, they are given to the TCP entity, which reconstructs the original byte streams.The IP layer gives no guarantee that datagrams will be delivered properly, so it is up to TCP to time out and (74) them as need be.

● Documentation of a software package is normally produced for two purposes. One is to explain the __(71)__ of the software and describe how to use them. This is known as __(72)__ because it is designed to be read by the user of the software. The other purpose of documentation is to describe the software，s internal composition so that the system can be maintained later in its life cycle. Documentation of this type is known as __(73)__.（71）A．plansB．costC．featuresD．schedules（72）A．system documentationB．user documentationC．vender documentationD．product documentation（73）A．system documentationB．user documentationC．vender documentationD．license documentation
Passage 2 A great deal of attention is being paid today to the socalled digital divide — the division of the world into the info(information) rich and the info poor. And that divide does exist today. My wife and I lectured about this looming danger twenty years ago. What was less visible then, however, were the new, positive forces that work against the digital divide. There are reasons to be optimistic.There are technological reasons to hope the digital divide will narrow. As the Internet becomes more and more commercialized, it is in the interest of business to universalize access — after all, the more people online, the more potential customers there are. More and more governments, afraid their countries will be left behind, want to spread Internet access. Within the next decade or two, one to two billion people on the planet will be netted together. As a result, I now believe the digital divide will narrow rather than widen in the years ahead. And that is very good news because the Internet may well be the most powerful tool for combating world poverty that we've ever had.Of course, the ue of the Internet isn't the only way to defeat poverty. And the Internet is not the only tool we have. But it has enormous potential.To take advantage of this tool, some impoverished countries will have to getover their outdated anticolonial prejudices with respect to foreign investment. Countries that still think foreign investment is an invasion of their sovereignty might well study the history of infrastructure (the basic structural foundations of a society) in the United States. When the United States built its industrials infrastructure, it didn't have the capital to do so. And that is why America's Second Wave infrastructure — including roads, barbors, highways, prots and so on — were built with foreign investment. The English, the Germans, the Dutch and the French were investing in Britain's former colony. They financed them. Immigrant Americans built them. Guess who owns them now? The Americans. I believe the same thing would be true in places like Brazil or anywhere else for that matter. The more foreign capital you have helping you build your Third Wave infrastructure, which today is an electronic infrastructure, the better off you're going to be. That doesn't mean lying down and becoming fooled, or letting foreign corporations run uncontrolled. But it does means recognizing how important they can be in building the energy and telecom infrastructures needed to take full advantage of the Internet.第55题：Digital divide is something _______ .A getting worse because of the InternetB the rich countries are responsible forC the world must guard againstD considered positive today

The third function is the (74), which is the logic documented in the DFDs, use cases, and functional requirements. The fourth function is the presentation logic, the display of information to the user and the acceptance of the user's commands. The three primary hardware components of a system are (75). A. data access componentsB. database management systemC. data storageD. data entities
The System Administrator wants to do a backup of the HMC and notices that there are two options on the HMC menu: Backup Critical Console data and Save Upgrade Data. Which of the following best describes the differences between the two options?（）A、Both options back up user and partition profile data. Only the Backup Critical Console Data backs up TCP/IP settings or preferencesB、Both options back up partition profile information. Only the Backup Critical Console Data backs up service function settings, such as Inventory Scout, Service Agent, and Service Focal PointC、The Backup Critical Console Data should be performed just before the HMC software update operation. The Save Upgrade Data should be performed each time configuration changes are made to the system or the HMCD、The Save Upgrade Data should be performed just before the HMC software update operation. The Backup Critical Console Data should be performed each time configuration changes are made to the system or the HMC
问答题Questions 1 to 5 are based on the following passage. Computer users fed up with hacker attacks and other security threats that exploit holes in Microsoft software are increasingly turning to alternatives such as open source Internet browsers developed by Mozilla. “It’s reflective of a trend that we’ve seen over the last year with more web users becoming frustrated with the Internet experience,” said Chris Hoffmann of the Mozilla Foundation, a non-profit group supported by Sun Microsystems, IBM and other companies, backing as an alternative to Microsoft. Much of that frustration has centered on Microsoft, which has been heavily criticized for producing software vulnerable to hand virus writers. Microsoft has responded with a series of patches designed to plug vulnerabilities in its Windows operating system, Internet Explorer web browser and other software. But computer owners are growing weary of continuously updating software to protect against new threats. One incident last month enabled hackers to gain access to web surfers’ computers by taking advantage of vulnerabilities in Microsoft’s browser. Hackers could then install remote access Trojan programs that enabled them to control a victim’s computer. The hackers could also install software to capture a victim’s keystrokes to steal data such as bank account numbers and passwords. Mr. Hoffmann hoped publicity stemming from Microsoft’s security woes(灾难) would translate into a market share increase for Mozilla’s software, which includes the new highly regarded Firefox Internet browser. But Mozilla suffered a setback last week when it was forced to issue a software patch to counter a newly discovered vulnerability affecting its Internet browsers. Still, Mr. Hoffmann said Microsoft’s security woes stem in part from the way its browser has been integrated into Windows for user convenience. Security experts agree that has made it easier for hackers to exploit computers running on Microsoft software. Others suggest Microsoft has been targeted by hackers and virus writers simply because more than 90 per cent of the world’s computers run on the software giant’s operating system. Questions: 1．What is the meaning of the phrase “fed up with” (Para.1)? 2．It can be guessed that the word “plug” (Para.3) means ________________. 3．Why more web users have become frustrated? 4．What happened to Mozilla’s Internet browsers last week? 5．How would Microsoft be less vulnerable?
