The Raspberry Pi is a credit-card-sized single-board computer, developed in the UK by the Raspberry Pi Foundation. The dinky device was created in order to supply schools with the means to teach basic computer science at a reasonable price. The device costs around £25, and is suitable for people of all ages. Raspberry Pi plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is capable of doing everything you’d expect a desktop computer to do, from browsing the internet to making spreadsheets, word-processing, and even playing games. There have been more than 3 million Raspberry Pi’s sold to date, and they are extremely popular in schools due to their low price.
Now, a new version of the Raspberry Pi barebones computer has been released, called the B+. The updated Raspberry Pi B+ uses less power than the previous models. The redesigned model has more connectors to help link it to other devices.
