The story of the computer
A computer is any machine that can be programmed with a set of instructions.
1837 In Britain, the first machine with a program was designed by Charles Babbage and his student Ada Lovelace. Charles wanted a machine to add up big numbers, but Ada realized that a computer program could do a lot more. She was the first computer programmer.
1936 British scientist Alan Turing read Ada’s ideas and created the Turing machine, the basic design of a computer system. The Turing machine could do all kinds of calculations, and it could also run different programs. This is the basis for all modern computers.
1940s Scientists built early computers in England and Germany. They were the size of a room!
1981 A US company designed the first PC (personal computer) for the general public. Experts didn’t believe that anybody wanted a computer at home. But in two years they sold thousands of them.
1971 Ted Hoff was the main inventor of the microprocessor, or “microchip”. This was a major breakthrough in the history of computers. Thanks to the microchip, computers and other electronic devices got faster and smaller very quickly.
1990s–present Smartphones—phones with computer software—arrived! Today’s smartphones can connect to the internet and run all kinds of different apps—in other words, they are small computers. The arrival of smartphones has started a new era in digital technology. Expressions such as “Wi-Fi”, “download” and “app” have become part of our daily lives.
The future Computer technology continues to develop. Some computers will be tiny—perhaps we will even have computers in our clothes. Scientists believe that quantum computers will be the next big breakthrough. They will be many times faster than today’s computers, and much more powerful.
While-reading
Listen to the recording. Underline the key people and events in the text.
e.g., the first machine with a program,
Charles Babbage, Ada Lovelace.
While-reading
Create a timeline of the history of computers. Include inventors, inventions and dates.
Use flag stickers to show the inventors’ nationalities (e.g. Ada Lovelace → British flag)
While-reading
Read the text again and answer the questions.
What did Charles Babbage and Ada Lovelace do in 1837
2. Who was Alan Turing and what did he do
3. Who was Ted Hoff What happened after his invention
4. What will be the next big breakthrough in computer technology

Role-play
Imagine that three historical figures are being interviewed by a reporter. Role-play in groups of four.
Roles:
Ada Lovelace, the first programmer
Alan Turing, inventor of the Turing machine
Ted Hoff, inventor of the microchip
A reporter
Steps:
Each student first prepares what to say (i.e. interview questions and answers).
Next, the reporter interviews the three historical figures about their achievements.
The historical figures then tell the reporter what they think of today’s computers.
Finally, the historical figures discuss what they think AI will be able to do in the future.
Who invented the World Wide Web How has it changed the world Watch a video clip about the digital revolution and answer the questions below.
What bad things about the internet does the speaker mention
Why does the speaker say that Tim Berners-Lee gave the world “a wonderful present”
Some internet companies become so big and powerful. People become addicted to computer games.
Because Tim Berners-Lee invented the web and gave it to the world for free. A lot of people benefit from it.
Who invented the World Wide Web How has it changed the world Watch a video clip about the digital revolution and answer the questions below.
Video script
The digital revolution
The world today is very different because of the web. Now there are three billion people online. The internet gives us information, friends, and a lot more. Life is easier. We can go online nearly everywhere—at home, outside and in cafés.
But some people think there are bad things about the web. Is it a good thing for these companies to be so big and powerful Can we stop people becoming addicted to computer games There are some big problems. But Tim Berners-Lee’s idea—to connect people who are not rich or powerful—is still true.
Kudjo is a successful farmer in Ghana and for him the internet is very important. At first, he didn’t know how to use the web. Then a friend gave him some practical lessons. Now he browses for information. The internet helps him to grow his crops and to sell them. He checks out the prices of different products. Then he can sell his products at the correct price.
He can compete with the big farmers now and he can earn more money. Kudjo feels connected to the world, not alone.
This is what Tim Berners-Lee wanted when he invented the web. He created something amazing and it’s still changing today. But he never earned money from it. He gave it away to the world for free because he wanted everyone to benefit from it. These young people in Africa today are doing exactly that. What a wonderful present!
