Computing Introduction

What is a computer? A computer is an electronic device that processes digital data.

Computers process data The computer is given some data to work with – data gets input into it. 2018

Computers process data It then does something to the data – it processes or changes it. 2018 Add on 1

Computers process data Some sort of result is produced – output comes out of it. 2019

Computers process data The computer is given some data to work with – data gets input into it. Hello

Computers process data It then does something to the data – it processes or changes it. Translate to French

Computers process data Some sort of result is produced – output comes out of it. Bonjour

Computers process data So computers are just like the function machines that you learn about in Maths. Process input output

Computers process data So computers are just like the function machines that you learn about in Maths. But computers do everything VERY FAST. They can do billions of things a second. Process input output

But how does a computer know what to do But how does a computer know what to do? How does it know how to process the data?

Computers run programs A program is a set of instructions.

Computers run programs The instructions in the program tell the computer what to do.

Computers are everywhere Simple computers are built in to many devices.

Computers are everywhere The computers control the electronic devices.

What other computer controlled devices can you think of What other computer controlled devices can you think of? What does the computer do?
