Computer networks may be (1) according to the network topology upon which the network is based, such as bus network, star network, ring network, mesh network, star-bus network, tree or hierarchical topology network. Network topology signifies the way in which devices in the network see their (2) relations to one another. The use of the term "logical" here is significant. That is, network topology is independent of the "physical" (3) of the network. Even if networked computers are physically placed in a linear arrangement, if they are connected via a (4), the network has a Star topology, rather than a bus topology. In this regard the visual and operational characteristics of a network are distinct; the logical network topology is not necessarily the same as the physical layout. Networks may be classified based on the method of data used to convey the data, these include digital and (5) networks.

三、阅读理解（在每个小题四个备选答案中选出一个正确答案，填在题末的括号中）（本大题共12小题，每小题2.5分，总计30分）

The future of Oracle's $7.4bn takeover of Silicon Valley rival Sun Microsystems is in doubt, after European and American regulators were left at loggerheads over the potential impact of the deal.

Officials at the European Commission have said that their preliminary investigation into whether the deal would damage competition had raised concerns - news which prompted the Department of Justice in Washington to issue its own, contrary, advice on the deal yesterday.

"After conducting a careful investigation of the proposed transaction between Oracle and Sun, the department's antitrust division concluded that the merger is unlikely to be anti-competitive," said Molly Boast, deputy assistant attorney general. "At this point in its process, it appears that the EC holds a different view. We remain hopeful that the parties and the EC will reach a speedy resolution."

The primary concern appears to be whether the deal would adversely affect the huge and lucrative computer database market, by bringing together under one roof Oracle's proprietary database systems and Sun's open source database software MySQL, which it bought in 2008 for $1bn.

Although Washington officials said they did not believe there would be any harm to consumers if the two companies - which command a significant share of the market - came together, European officials opened a formal investigation in September.

"The commission has to examine very carefully the effects on competition in Europe when the world's leading proprietary database company proposes to take over the world's leading open-source database company," said competition commissioner Neelie Kroes at the time.

The difference of opinion adds a further layer of complexity to the deal in which Oracle, the software maker, would bail out Sun and take control of its business - which also includes computer servers, workstations and software products.

The surprise deal between the two companies was announced in April, after struggling Sun had indulged in a long flirtation with other technology companies including IBM.

Oracle said it would fiercely object to the position of the European regulators, which it felt had no merit.

"The commission's statement of objections reveals a profound misunderstanding of both database competition and open- source dynamics," the company said in a statement.

21) Why EC has some doubt on the merge of Oracle and Sun?

a) The merge may harm the marketing competition.

b) The merge may harm the Europe business company.

c) The merge may bring chaos in database market.

d) The merge may gain US more power.

22) What is the attitude of Oracle?

a) They say that EC has no right to judge the merge.

b) They say that it's because of envy.

c) They say that the doubt is a misunderstanding.

d) They say that they will consider the suggestion.

23) According to the passages, what is the probable solution EC suggests?

a) Stop the merge.

b) Another company come in to buy Sun.

c) Let Sun bankrupt.

d) Oracle give up some control over MySQL.

24) At the same time, what US government said?

a) They agreed with EC.

b) They agreed with Oracle.

c) They run a independent investigation and got a different conclusion with EC.

d) They said nothing about the deal and the quarrel.

25) What is the main difference between each part?

a) It's about the price of the deal.

b) It's about the proprietary database Oracle and the free software MySQL.

c) It's about marketing monopoly.

d) It's about the interests of Sun's stockholder.

Now that you know some of the benefits provided by .NET, let’s preview three key (and interrelated) entities that make it all possible: the CLR, CTS, and CLS. From a programmer’s point of view, .NET can be understood as a runtime environment and a comprehensive base class library. The runtime layer is properly referred to as the common language runtime, or CLR. The primary role of the CLR is to locate, load, and manage .NET types on your behalf. The CLR also takes care of a number of low-level details such as memory management; creating application domains, threads, and object context boundaries; and performing various security checks.

Another building block of the .NET platform is the Common Type System, or CTS. The CTS specification fully describes all possible data types and programming constructs supported by the

runtime, specifies how these entities can interact with each other, and details how they are represented in the .NET metadata format.

Understand that a given .NET-aware language might not support each and every feature defined by the CTS. The Common Language Specification (CLS) is a related specification that defines a subset of common types and programming constructs that all .NET programming languages can agree on. Thus, if you build .NET types that only expose CLS-compliant features, you can rest assured that all .NET-aware languages can consume them. Conversely, if you make use of a data type or programming construct that is outside of the bounds of the CLS, you cannot guarantee that every .NET programming language can interact with your .NET code library.

26) The benefit of .NET is possible by

a) The power of Microsoft

b) Three key entities: CLS, CTS, CLR

c) Thousands of users

d) No other competitor

27) From an user’s view, .Net is

a) CLR and CTS

b) CLR and CLS

c) CTS and CLS

d) None of above

28) According to the passages, CTS is kind of

a) Language specification

b) User interface

c) Resource center

d) Base class library

29) According to the passages, it’s not implicit that

a) There are many languages that .NET can support

b) Not every feature defined by the CTS is supported in every language

c) CLS gives the restrict of each language

d) CTS is not finished developing.

In computing, a keyboard is an input device, partially modeled after the typewriter keyboard, which uses an arrangement of buttons or keys, to act as mechanical levers or electronic switches. A keyboard typically has characters engraved or printed on the keys and each press of a key typically corresponds to a single written symbol. However, to produce some symbols requires pressing and holding several keys simultaneously or in sequence. While most keyboard keys produce letters, numbers or signs (characters), other keys or simultaneous key presses can produce actions or computer commands.

In normal usage, the keyboard is used to type text and numbers into a word processor, text editor or other program. In a modern computer, the interpretation of keypresses is generally left to the software. A computer keyboard distinguishes each physical key from every other and reports all keypresses to the controlling software. Keyboards are also used for computer gaming, either with regular keyboards or by using keyboards with special gaming features, which can expedite frequently used keystroke combinations. A keyboard is also used to give commands to the operating system of a computer, such as Windows' Control-Alt-Delete combination, which brings up a task window or shuts down the machine.

30) What is the model of keyboard?

a) Old typewriter keyboard

b) Laser printer

c) Fax machine

d) Speaker

31) In a modern computer, who is response to interpret a keypress?

a) A circuit

b) A programmer

c) A software

d) A communication line

32) According to the passages, this is NOT a function of keyboard:

a) Input text

b) Play game

c) Send control command

d) Make sound
