Raspberry Pi boards are powerful single-board computers and have everything that a classic computer would normally have. They are equipped with a processor, RAM, and ports for peripherals such as monitors, keyboards, and mice.
A Raspberry Pi board can be used for a variety of purposes: It acts as a server for databases and files or as a web server. In robotics or home automation projects, the computer is often used as a control unit. The devices can be further specified with accessories such as camera modules, displays or expansion boards.
