Well we are back with a bang.

On Tuesday we went over the 2010 paper we used for exam practice, 2011 Mock. Here is the 2011 Mock Marking Instructions. If you want to ask any question just put it in a comment.

We also started the new peripheral topic in Computer Systems and have covered Keyboards, Scanners & Sound Cards. Search the blog to look for previous articles on these devices, there is more than one. There are a number of non traditional keyboards out there. The net even has articles on how to build a 3D scanner, I would have to say though that milk scanner is a little bit messy. With sound cards we discussed the merits of digital Vs audio, we used scratch’s soundgraph project to look at sample rates.
