[不定项选择题]资料:Acknowledging that so-called cloud computing will blur the distinctions between computers and networks, about two dozen big information technology companies plan to announce a new standards-setting group for computer networking. The group, to be called the Open Networking Foundation, hopes to help standardize a set of technologies pioneered at Stanford and the University of California, Berkeley, and meant to make small and large networks programmable in much the same way that individual computers are.
The changes, if widely adopted, would have implications for global telecommunications networks and large corporate data centers, but also for small household networks. The benefits, proponents say, would be more flexible and secure networks that are less likely to suffer from congestion. Someday, they say, networks might even be less expensive to build and operate. The new approach could allow for setting up on-demand "express lanes" for voice and data traffic that is time-sensitive. Or it might let big telecommunications companies, like Verizon or AT&T, use software to combine several fiber optic backbones temporarily for particularly heavy information loads and then have them automatically separate when a data rush hour is over. For households, the new capabilities might let Internet service providers offer remote services like home security or energy control.
The foundation's organizers also say the new technologies will offer ways to improve computer security and could possibly enhance individual privacy within the e-commerce and social networking markets. Those markets are the fastest-growing uses for computing and network resources. While the new capabilities could be crucial to network engineers, for business users and consumers the changes might be no more noticeable than advances in plumbing, heating and air-conditioning. Everything might work better, but most users would probably not know- or care- why or how.
The members of the Open Networking Foundation will include Broadcom, Brocade, Ciena, Cisco, Citrix, Dell, Deutsche Telekom, Ericsson, Facebook, Force10, Google, Hewlett-Packard, I.
B.M., Juniper, Marvell, Microsoft, NEC, Netgear, NTT, Riverbed Technology, Verizon, VMWare and Yahoo. "This answers a question that the entire industry has had, and that is how do you provide owners and operators of large networks with the flexibility of control that they want in a standardized fashion." said Nick McKeown, a professor of electrical engineering and computer science at Stanford, where his and colleagues' work forms part of the technical underpinnings, called OpenFlow.
The effort is a departure from the traditional way the Internet works. As designed by military and academic experts in the 1960s, the Internet has been based on interconnected computers that send and receive packets of data, paying little heed to the content and making few distinctions among the various types of senders and receivers of information. The intelligence in the original Internet was meant to reside largely at the end points of the network-the computers-while the specialized routing computers were relatively dumb post offices of various size, mainly confined to reading addresses and transferring packets of data to adjacent systems. But these days, when cloud computing means a lot of the information is stored and processed on computers out on the network, there is growing need for more intelligent control systems to orchestrate the behavior of thousands of routing machines. It will make it possible, for example, for managers of large networks to program their network to prioritize certain types of data, perhaps to ensure quality of service or to add security to certain portions of a network. The designers argue that because OpenFlow should open up hardware and software systems that control the flow of Internet data packets, systems that have been closed and proprietary, it will cause a new round of innovation focused principally upon the vast computing systems known as cloud computers.
It can be inferred from the passage that____
A.The open networking foundation will be led by Stanford and the university of California, Berkeley.
B.With the setting of new standards, operators of large networks will have more flexibility of control.
C.People will have a better understanding of the distinctions between computers and networks thanks to cloud computing.
D.Cloud computing will involve more routing computers than the traditional internet.

[简答题]
资料一:2010年3月5日,光明食品集团公司在上海宣布,已和全球领先的保健品零售企业美国健安喜(GNC)公司签署谅解备忘录,建立战略合作关系,通过合资企业健安喜(中国)共同进军中国保健品市场。光明食品集团是中国最大的大型国有食品产业集团之一,2009年销售规模逾700亿。
资料二:一个促成合作的重要契机在于,中国保健品市场目前仍然未全面对外资开放。根据《外商投资产业指导目录(2007年修订)》规定,设立超过30家分店、销售来自多个供应商的不同种类和品牌商品的连锁店必须要由中方控股等,这使得众多外资医药零售商都希望在中国能寻找到合适的中方伙伴。
健安喜(GNC)也面临这样的发展瓶颈。尽管健安喜(GNC)产品线非常丰富,涉及体重控制类、运动类、男女保健、健脑、睡眠辅助、草本植物萃取、维生素、矿物质等上千种产品,在美国也拥有超过6000家的销售点,但在中国市场上它必须得寻找到合作伙伴。
美国健安喜公司董事长JoeFortunato透露,双方此次合作的主要基础是,光明食品在中国拥有强大的产品组合、分销和零售通道。这为健安喜在中国大陆达成战略目标奠定了合作基础。
据悉,双方将在2010年中期完成合资公司的组建和产品的市场投放,双方合资的销售平台健安喜(中国)将在中国的大中城市推广健安喜(GNC)品牌,发掘潜在的零售和分销市场机会,并在条件成熟时实现本土化生产。
资料三:光明食品集团董事长王宗南强调,“作为一个以食品产业为核心的都市产业集团,光明食品集团多年来致力于打造一、二、三产业为一体的完整食品产业链,形成覆盖上游原料资源、中间生产加工、下游流通渠道的大格局,从而向消费者提供安全美味的产品。现阶段根据国家‘走出去’的战略,我们正不断推进国际化进程,走出本土市场,集聚全球范围内的各种资源来加强光明在其他国际市场的影响力,让所有向往健康生活的消费者都能享受到高品质产品。”
据有关资料显示,欧美国家的消费者平均用于保健品方面的花费占其总支出的25%以上,而我国只有0.07%。这表明,保健品市场潜力巨大,以目前全球保健品占整个食品销售的5%来推算,我国保健品消费还将大幅增长。
