This is a book about A-Level Computing. It aims to fit in with the AQA GCE A-Level Computing syllabus but is not endorsed by AQA. It should be useful as a revision guide or to find alternative explanations to the ones in your textbook. If you haven't heard of an A-Level then this book probably won't be of much interest to you but you can find out about them at Wikipedia.

How to read the book
You will meet several coloured boxes, here are their meanings:
What the specification says you must learn for each chapter
Example questions and how to solve them
to check if you were right
Topics that aren't examined but you might be interested in
There will be a lot of concepts that you need to be familiar with, definitions are highlighted like so:
- To be awarded an AS (Advanced Subsidiary) Level qualification in Computing, a student must take the 2 AS modules.

The book is split into the four units. Each unit is split into chapters with each chapter covering the topics for that module.
