Raspberry Pi

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

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 ports, and an Ethernet port.
Model B+: successor to Model B, with four USB ports instead of two, and a combined audio/video 4-pole jack.
Raspberry Pi 2 Model B: same shape and size as Model B+ but with a quad core 900MHz processor and 1GB RAM, making it much faster than the older versions to use^[1].

Differences from other computers

The Raspberry Pi is not a regular computer. It has the ARM processor architecture. It is the one used in smartphones.
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.
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.
The Raspberry Pi does not have a hard drive. You have to use an SD card.
The Raspberry Pi does not come with an operating system by itself. You have to load either NOOBS^[2] (recommended), or load a Linux distribution that works with the Raspberry Pi (for example, Raspbian.)
