[填空题]The Internet is the world’s largest group of cooperating computer networks. All the computers on the more than 100,000 networks that comprise the lnternet voluntarily use the same technical standards for their network date so that any of the computers on any of the networks can exchange messages with any other. Each message sent is broken up into small chunks of roughly uniform (相同的) size, called packets; each packet is sent along to its destination. If a packer’s destination is on a different network from its origin, the packet is switched from network to network until it reaches its destination. The destination computer reassembles incoming packets into the desired message. The "packet switched" design has let the Internet grow from its original two networks to its current size and beyond without any fundamental changes in the way that it works.
The Internet’s origins date from the late 1960s. During the 1980s, many new networks connected to the growing Interact-including both

The World Bank is undeniably in crisis. But not because its president, Paul Wolfowitz, got his girlfriend a raise.
It is the Wolfowitz saga that has been grabbing all the headlines, of course. The Iraq- war architect was plucked from the Defense Department and deposited by President George W. Bush at the World Bank in 2005 (by tradition, the U.S. President picks the bank’s chief).
