[单项选择]The first week of July 1776 was a busy one for Thomas Jefferson. The Declaration of Independence, which he largely wrote, was adopted on the fourth. But he chose the same week to begin keeping a record of the temperature change in a notebook. This wasn’t a single example: for eight years, as president, Jefferson made detailed notes on the seasonal availability of various vegetables in the markets of Washington, DC.

So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way the computer network system would keep on working all the time. At first the Internet was only used by the government, but in the 1970s, universities, hospitals and banks began to use it, too.
