Raspberry Pi
The Raspberry Pi is a credit-card-sized single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools.
The Raspberry Pi is manufactured through licensed manufacturing deals with Element 14/Farnell and RS. Both of these companies sell the Raspberry Pi online.
The Raspberry Pi has a Broadcom BCM2835 system on a chip (SoC), which includes a 700MHz ARM11 processor (The firmware includes a number of "Turbo" modes so that the user can attempt overclocking, up to 1 GHz, without affecting the warranty), VideoCore IV GPU, and was originally shipped with 256 megabytes of RAM, later upgraded to 512MB. It does not include a built-in hard disk or SSD, but uses an SD card for booting and long-term storage. The Foundation's goal is to offer two versions, priced at US$25 and US$35. The Foundation started accepting orders for the higher priced model B on 29 February 2012, and the lower cost model A on 4 February 2013.
The Foundation provides Debian and Arch Linux ARM distributions for download. Also planned are tools for supporting Python as the main programming language, with support for BBC BASIC, C, and Perl.
On 17 December 2012 the Raspberry Pi Foundation, in collaboration with IndieCity and Velocix, opened the "Pi Store", as a "one-stop shop for all your Raspberry Pi (software) needs". Using an application included in Raspbian, users can browse through several categories and download what they want. Software can also be uploaded for moderation and release.
Raspbian
Raspbian is a Debian variant based on the ARM hard-float (armhf)-Debian 7 'Wheezy' architecture port but optimised for the ARMv6 instruction set of the Raspberry Pi hardware. Raspbian provides over 35,000 available deb packages pre-compiled for easy installation on a Raspberry Pi computer, specifically tuned for optimal performance on the Raspberry Pi ARM11 hardware. The Raspbian distribution basically contains the LXDE desktop environment, the Openbox window manager, the Midori web browser, software development tools and example source code for multimedia functions. Raspbian is a project of a small, dedicated team of developers, and is not affiliated with the Raspberry Pi Foundation.
There is also the Raspbian Server Edition (RSEv2.2), which is a stripped down version of Raspbian with other software packages bundled as compared to the usual desktop-oriented Raspbian' distribution. In total, 242 software packages were removed from the original version of Raspbian.
