How computers have changed

Computers are everywhere today and they can do things very fast. In the past they were much slower and much bigger.

Computers have changed a lot over time. There have been some important people who have helped change what computers can do: Charles Babbage, Ada Lovelace and Alan Turing.

Watch this video and find out a little more about the history of computers.

Who were they?

Ada Lovelace Ada Lovelace was the first person to write computer programs. She predicted that one day machines would do more than just maths.

Charles Babbage Charles Babbage designed a machine called the Analytical Engine 200 years ago. If it had been built this machine would have been the first modern computer.

Alan Turing Alan Turing created machines during the war. They helped people read secret coded messages. He is sometimes called the "Father of Computer Science".
