The processor is similar to the one used in many of the smart phones. It has a couple of USB ports and Ethernet port to connect to the internet. It has 1080p video playback and hardware accelerated graphics. It can plug into any TV and can power 3D graphics and Blu-ray video playback.
Raspberry Pi is like a skeleton of a computer, showing the inner components of the mini PC. Inspired by computers like the BBC Micro and the Commodore 64 in the 1980s, the group of engineers set out to build a new programmable machine for a new generation.

The project came about when a group of Cambridge-based computer programmers noticed that fewer and less-qualified students were applying for computer science courses at Cambridge University.
