Raspberry Pi (abbreviated as RPi or RasPi) is a very cheap credit card-sized Linux computer developed by the British charity Raspberry Pi Foundation, originally developed to teach computer programming to students from poor countries around the world.
Since then, because of its powerful functions, its small size and low cost, Raspberry Pi has been widely known around the world and become popular, and not only it has been used for computer education for children that is its original development purposes, but also many people have purchased and used it for their own business or personal purposes.
