The Raspberry Pi was designed by the Raspberry Pi Foundation to provide an affordable platform for experimentation and education in computer programming. The Raspberry Pi can be used for many of the things that a normal desktop PC does, including word-processing, spreadsheets, high-definition video, games, and programming. Raspberry Pi 3 Model B is the earliest model of the third-generation Raspberry Pi. It replaced Raspberry Pi 2 Model B in February 2016.

The Raspberry Pi can be used for many of the things that a normal desktop PC does, including word-processing, spreadsheets, high-definition video, games, and programming. The Raspberry Pi 3 Model B+ is the final revision in the Raspberry Pi 3 range, maintaining the same mechanical footprint as both the Raspberry Pi 2 Model B and the Raspberry Pi 3 Model B.

Raspberry Pi 4 Model B 2GB is a miniature single-board computer that can fully replace a desktop PC running Linux. The platform is suitable not only for web surfing and application development but can also serve as the "brain" for a robot or smart home, a media center, a node in a distributed computing system, or an industrial controller.
