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.

考题 资料:Tencent Holdings Ltd has announced that it will fully open up its big data platform and machine learning technology in a move to build a "sharing economy" based on cloud services. Enterprises will be able to use a set of big data analysis tools developed by Tencent, helping them gain a better understanding of their clients and improve their products. The Shenzhen-based internet giant, which owns instant messaging tools QQ and WeChat, has years of experiences storing and analyzing huge amounts of data. The opening of its core technologies is part of Tencent's efforts to develop cloud services, an area which many other big companies including Alibaba and Baidu are also tapping into. "Development of a sharing economy is closely related to cloud services" said Ma Huateng, chairman of Tencent." Like transportation, accommodation and many other areas. cloud services are also a kind of sharing economy. "He said cloud computing has become one of the key areas Tencent focuses on and the company is dedicated to opening its IT resources and technological capabilities to outsiders." In the past, enterprises were only users of internet technology. Now, as they engage themselves in the cloud, they are becoming a part of the internet ecosystem," Ma said at the 2016 Tencent Cloud Summit held in Shenzhen this week. Cloud technology has achieved greater importance in recent years as more and more Chinese enterprises integrate themselves deeper with the internet. However, it remains difficult for companies, especially smaller ones, to build their own data center because it involves large capital investment and a waste of resources, said Dowson Tong. senior executive vice-president of Tencent. Cloud services help enterprises get access to more resources while reducing their operating costs, Tong said. According to the 2016 Internet Trends report, services provided by Tencent are the most commonly used by Chinese internet users. More than 50 percent of their time on the internet is spent on Tencent services." We are not offering cloud services as a separate business. Instead, it is a part of Tencent's entire strategy. Enterprises will be able to get access to all Tencent platforms by using its cloud services," Ma said. What is probably the title of this passage?A.Cloud services help enterprises get access to resources. B.Tencent's efforts to develop cloud service. C.Tencent opens up big data platform to boost sharing economy. D.Cloud technology.

考题 资料:The personal computer was a revolution in information technology that spawned a $50 billion hardware business, with another $30 billion in software and peripherals (eg. mouse, keyboard, printer, etc.) by 1991. During its short 15 years, the industry evolved through three successive periods. During its first 5 to 6 years, it was characterized by explosive growth and multiple, small competitors vying for a piece of the market. From 1981 to 1985, the industry became a battle for standards and retail shelf space. The third era was one of increasing fragmentation. From 1986 through 1991-1992, new manufacturers from around the world grabbed from the industry leaders as new channels of distribution emerged and product innovation as well as revenue growth slowed. During the early years of the industry, venture capital in the U.S. encouraged the entry of new firms that offered products in every conceivable shape and size. By 1980, new entrants flooded the market, prompting distinct standards and unique technical features. Almost every firm had a different configuration of hardware and software. The first PC had relatively little speed or memory. However, even these early computers allowed managers to perform tasks that were very time consuming. What happened in the third era?A.The small companies experienced a harsh life. B.People preferred PCs of big brands. C.The big companies didn’t earn as much as they did in the past two periods. D.The companies made standards on the configuration.

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.    Which of the following is NOT true about OpA.It deviates from the traditional Internet. B.It is meant to help with the storing and processing of information on computers. C.It is an initiative of Nick McKeown and his colleagues. D.It will trigger new innovations in the field of cloud computing.
