This section contains interactive demonstrations of key computing concepts. The pages were created to cover the KS3 National Curriculum for Computing (in England) but are suitable for anyone just beginning to learn about computing. I also recommend learning to program with Python or Just BASIC if you are a beginner - there are some sample tasks in the Programming section.
There are also some videos on the Computing and ICT in a Nutshell YouTube channel to accompany these pages, e.g. those on number bases and how to use Boolean Logic in your programming.
