New series on YouTube narrated by Bill Gates and others detailing “How Computers Work”
Part of the Code.org Non-profit Computer Science Educational Program. Series of six videos including “What makes a computer a computer?”, “Binary and data”, “Circuits and logic”, “CPU, memory and I/O”, and “Hardware and software”.
I reviewed a couple of videos and I must admit he does a very good job. If you are interested in the basic
principles of how computers work this is a good resource.
