The Internet is the biggest source of information in the world, consisting of millions of pages of data. In 1969, DARPA, a US defence     1     (organize), developed a way for all their computers to “talk” to each other through the telephone. They created a network of computers and only the US army could use     2     in the following 15 years. Then in 1984, the US National Science Foundation started the NSF network, also known     3    the Inter-network or ”Internet”. It then became possible for universities to use the system as well. The World Wide Web,     4     (invent) in 1991 by an English scientist, Tim Berners-Lee, is a computer network that makes the information from millions of websites accessible to computer users. At the moment, about 80 % of web traffic is in English, but by 2020, Chinese could take    5    lead. Obviously, it was Berners-Lee     6    made it possible for everyone to use the Internet, not just the universities and the army. He designed the first “web browser”,     7    allowed computer users to access documents from other computers. With the web and the Internet     8    (grow), the number of Internet users rose     9    (rapid) from 600,000 to 40 million within 5 years.

So far, the Internet     10     (create) thousands of millionaires all over the world, but Berners-Lee is not one of them.

5G is developing, but most of us aren't really sure what it is or the reason     1     we need it. A big part of the reason is that 5G means more than one thing. If you ask different people, you     2    (provide) with different answers.

Experts believe that 4G is on     3     way out. In 2020, the U.K. is expected to use 5G. At present, it is unknown exactly what influence 5G will have on people's life but it is widely thought that 5G will     4     (definite) be faster than any generation of networks we have used previously.

Work will likely become much easier as 5G will allow quicker downloads and a better ability to work online even if there is no wi-fi connection. With the     5     (develop) of 5G, driverless cars will be able to communicate     6     other vehicles, which can reduce road accidents by about 10%, One of the most     7     (impress) things will be that people can see which seats on a train are accessible to     8     (they) when it arrives at the station.     9     (get) around the world will also be more convenient.

A number of     10     (company) are now working on bringing 5G to the market. It remains to be seen how much of the country 5G will cover and whether everyone will be able to benefit from it.
