A Raspberry Pi Model B
The Raspberry Pi 2 Model B is faster than the older models. It was released in February 2015.

The Raspberry Pi is a computer that is as big as a credit card. People call it a single-board computer because it comes with only one circuit board. This is not the only single-board computer. There are more of this kind of computer. The Raspberry Pi was created in the UK by the Raspberry Pi Foundation. Its purpose was to help high school students learn computer science. Lots of people use it to make things like cameras, gaming machines, and many more things. Some people make even more unusual things with it.

Different types[change | change source]

The Raspberry Pi is available in two different types:

  • Model A: $25, comes with one USB port, an HDMI port, with a composite video port, and a headphone jack to plug in to speakers or headphones.
  • Model B: $35, same as Model A, but with two USB port, and an Ethernet port.

Differences from other computers[change | change source]

  1. The Raspberry Pi is not a regular computer. It has the ARM architecture. It is the one used in smartphones.
  2. The Raspberry Pi does not use Windows or Mac OS X. It uses Linux, which can be used on almost any computer. Linux is not as popular as Windows or Mac.
  3. You can not use the Internet with the Raspberry Pi out of the box. You have to connect an adapter for Wi-Fi, or connect through Ethernet.
  4. The Raspberry Pi does not have a hard drive. You have to use an SD card.
  5. The Raspberry Pi does not come with an operating system by itself. You have to load either NOOBS[1] (recommended), or load a Linux distribution that works with the Raspberry Pi (for example, Raspbian.)

  1. NOOBS stands for New Out Of Box Software. It comes with Arch Linux ARM (very hard to use), OpenELEC (media center), Pidora (Fedora Linux remix), raspbmc (media center), Raspbian (recommended), and RISC OS (very hard to start using?).
