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

What is:
Credit card sized low cost computer used by solely or by integrating with other circuits.
Found by Raspberry Pi Foundation(trustee-Eben Upton)
Aiming student experiments with low investment.
The computer uses less power than a light bulb
System on a chip, a computer on a single low voltage chip
Full fledged Linux OS Installed

background:
Started the research in 2006.
Pi Foundation was responsible
Eben Upton, Pi Foundation trustee teamed with Universities, Students, Programmers and tied up with Industries.
First model was based on Atmel ATmega644 microcontroller assembled with a USB & HDMI

features:
Broadcom BCM2835 ‘System on a chip’(Soc)
Need SD card with an OS preloaded before booting the Raspberry Pi. Customized Linux Distribution supported .
GPIO to interconnect with other Circuit boards OS can interact with them
Main programming language-Python with supporting languages BBC BASIC, C, PERL

Variants:
2 models:model A & model B
