Over the years, additional networks joined which added【C6】______to more and more computers. The first international connections, to Norway and England, were added in 1973. Today thousands of networks and millions of computers are connected to the Internet. It is growing so quickly that nobody can say【C7】______how many users "on the Net".
The Internet is the largest repository (知识库) of information which can provide very large network resources.
