Image of computer generations

In simple terms, a computer is a machine that takes input from the user and gives output.

Basically, you present the computer with a command and it follows it to produce a result.

Computers have a microprocessor that makes instant calculations.

Lots of things have microprocessors, such as your watch, your washing machine, your mouse and even your mobile phone.

Which is what makes them an essential part of our lives.

Let’s kick this off with this interesting mind-opener:

Ever wondered what happens when you click the Refresh option on your Windows desktop?
