BBC Bitesize

BBC Bitesize covers a wide range of input and output devices. Key concepts are clearly explained. The great thing about the BiteSize site is that it links to a series of related resources, including student activities, news article links, and online dictionaries and encyclopedias.

IGCSE ICT has notes on many topics (including input and output devices) that are useful for a range of ICT and Computing courses. The notes are very comprehensive, clearly divided into sections, well illustrated, and easily understandable for students. This is a good starting point for a lot of topics - not just for the IGCSE course.

TeachICT: detailed notes covering printers, screens, speakers, and more. Teach-ICT does have a range of activities for most topics, though they tend to be a bit gamey and only really appealing to younger students.
