The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It is a capable little computer which can be used in electronics projects, and for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. We want to see it being used by kids all over the world to learn programming.
There are two models, A and B. The Model A has 256MB RAM, one USB port and no Ethernet (network connection). The Model B has 512MB RAM, 2 USB ports and an Ethernet port.
NOOBs stands for New Out of Box Software. It is our recommended installation method. It allows you to install the distro of your choice even if you have little to no computing or Linux experience. A noob is someone who is inexperienced: the title should be worn with pride. After all; the only people who were never a noob at some point were those who never bothered to learn anything at all!
The Raspberry Pi measures 85.60mm x 56mm x 21mm (or roughly 3.37″ x 2.21″ x 0.83″), with a little overlap for the SD card and connectors which project over the edges. It weighs 45g.
