问题     Read the following article about the computer industry.
    For each question (23-28) on the opposite page, choose the correct answer.
    Mark one letter (A, B or C) on your Answer Sheet.
                    COMPUTER INDUSTRY
The amount of digital information increases tenfold every five years. Moore’s law, which the computer industry now takes for granted, says that the processing power and storage capacity of computer chips double or their prices halve roughly every 18 months. The software programmes are getting better too. Edward Felton, a computer scientist at Princeton University, reckons that the improvements in the algorithms driving computer applications have played as important a part as Moore’s law for decades.
A vast amount of that information is available to all. By 2013 the amount of traffic flowing over the Internet annually will reach 667 Exabyte’s, according to Cisco, a maker of communications gear. And the quantity of data continues to grow faster than the ability of the network to carry it all.
People have long complained that they were swamped by information. Back in 1917 the manager of a Connecticut manufacturing firm complained about the effects of the telephone: "Time is lost, confusion results and money is spent." Yet what is happening now goes way beyond incremental growth. The quantitative change has begun to make a qualitative difference.
This shift from information scarcity to excess has broad effects. "What we are seeing is the ability to have economies form around the data—and that to me is the big change at a societal and even macroeco-nomic level," says Craig Mundie, head of research and strategy at Microsoft. Data are becoming the new raw material of business: an economic input almost on a par with capital and labour. "Every day I wake up and ask, ’ how can I flow data better, manage data better, analyse data better?’" says Rollin Ford, the CIO of Wal-Mart.
The speed of the digital information is faster than
选项 A、the processing capacity of the computer system.
B、the production of the computer.
C、the performance of the Internet.
答案A
解析 文中第二段倒数第3行指出：And the quantity of data continues to grow faster thanthe ability of the network to carry it all．即：数据的总量持续增长，速度快于网络的承载能力。文中的the ability of the network to carry it all与选项A中的the process-ing capacity of the computer system所表达的内容吻合。选项B和选项C在文中没有提及过，故不选。
