People who have changed the world.
a lot of people have changed our lives in the least 100 years. Inventors, for example,
have created the microchip, a small electronic component which is an important part
of today’s computers and televisions. Scientists have discovered penicillin, a
substance which kills bacteria, and DNA, a molecule that forms the basis of life.
Who are the most important people today? This week we consider Sir Tim Berners-Lee, a
British computer scientist who invented the world wide web. The world wide web (WWW)
is a system of linked hypertext documents, or web pages, which is part of the internet. You
can access these pages through a web browser.
Sir Tim had the idea for the web while he was working in Switzerland at a famous
Laboratory called CERN.
Scientists came from all over the world to work at CERN. They all had different types of
computers and they found it impossible to send information from one computer to another.
Sir Tim wrote some special programs to help them share information. Eventually he wrote a
computer language called HTML (HyperText Markup Language) to help people send and
receive computer files.
When Sir Tim connected his computer language to the internet the World Wide Web was
born!
Scientists at CERN created the first hypertext website and they put it online on August 6th,
1991. Today there are more than 50 billion websites! People use the web to buy and sell
things, look for information, listen to music, write blogs, show their photos and much more
