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.

The future
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.

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.
