The Raspberry Pi is a credit-card-sized single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of stimulating the teaching of basic computer science in schools.
The Raspberry Pi is manufactured through licensed manufacturing deals with Element 14/Premier Farnell and RS Electronics. Both of these companies sell the Raspberry Pi online.
The Raspberry Pi has a Broadcom BCM2835 system on a chip (SoC),[3] which includes an ARM1176JZF-S 700 MHz processor (The firmware includes a number of "Turbo" modes so that the user can attempt overclocking, up-to 1 GHz, without affecting the warranty),[4] VideoCore IV GPU, and originally shipped with 256 megabytes of RAM, later upgraded to 512MB. It does not include a built-in hard disk or solid-state drive, 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 on 29 February 2012.the Foundation provides Debian and Arch Linux ARM distributions for download.[16] Also planned are tools for supporting Python as the main programming language, with support for BBC BASIC, (via the RISC OS image or the "Brandy Basic" clone for Linux), C, and Perl.
On December 17, 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 you can browse through several genres and download what you want. Some commercial software is also included, although most software will be free. It's possible however to "tip" the creator of the software. Software can also be uploaded for moderation and release, and you can upload not only application software but also other binaries, raw Python code, images, audio or video, and other types of content.
