The Raspberry Pi has been designed as a cost effective option for use in school environments. One of the great things about the Raspberry Pi is that offers a wide variety of Operating Systems (OSs) for users to make use of in their projects, or to simply learn and tinker with. The official Raspberry Pi site (http://www.raspberrypi.org">www.raspberrypi.org) offers free, downloadable images for nine different operating systems.
Last week, I mentioned that there are a variety of operating systems available for the Raspberry Pi. One of the easiest for those just starting out is Raspbian Wheezy, which is based on Debian Linux. This process requires a computer and your microSD card, which will be the memory for your Raspberry Pi. You can access the Wheezy image on the Raspberry Pi website (https://www.raspberrypi.org/downloads). I used a microSD card with an adapter for my laptop.
