The history
OF COMPUTERS
Charles Babbage and Ada Lovelace
The modern computer was Charles Babbage’s idea. The
machine he wanted to build, called a ‘difference engine’,
was special because it had all the parts that a modern
computer has. It could save information and was also
a kind of printer. Ada Lovelace was the first computer
programmer. She had the idea for ‘software’ – a way of
telling a computer to do different things.
The abacus
People still use abacuses today in many parts of
the world, especially to teach maths to children. Of
course, they are very different from modern computers,
but the idea is the same – to answer difficult maths
questions much more quickly than a human can.
Modern computers
From the 1950s, computers got smaller,
faster and cheaper. Today, the smallest
mobile phones have more memory than the
biggest early computers. And computers are
getting better all the time. However, they
are not perfect. One of the worst problems
is computer viruses. You can lose a lot of
information when one gets on your machine.
Be careful about what you download from
the internet.
The Antikythera Mechanism
In 1900, a group of people diving near
the Greek island of Antikythera found this
machine on the sea floor. For many years, no
one understood what it was or how it worked.
Scientists now say it was used to find out the
positions of the sun, moon and stars. Many
people call it the world’s earliest ‘computer’.
