Raspberry Pi | What is it ?

A small and affordable computer that you can use to learn programming

A Raspberry Pi is a debit card-sized computer originally designed for education, inspired by the 1981 BBC Micro. Creator Eben Upton's goal was to create a low-cost device that would improve programming skills and hardware understanding at the pre-university level. But thanks to its small size and accessible price, it was quickly adopted by many people for projects that require more than a basic microcontroller like Arduino devices.

The Raspberry Pi is slower than regular computer but still it is widely used because of its small size and low price. It is a complete linux computer that can do all the expected works at very low power consumption.

Here is a small video that can help you to understand it more 

Is the Raspberry Pi open hardware?

The Raspberry Pi is open hardware, with the exception of the primary chip on the Raspberry Pi, the Broadcomm SoC which runs many of the main components of the board–CPU, graphics, memory, the USB controller, etc. Many of the projects made with a Raspberry Pi are open and well-documented as well and are things you can build and modify yourself.

What kind of operating system does the Raspberry Pi run?

The Raspberry Pi was designed for the Linux operating system, and many Linux distributions now have a version optimized for the Raspberry Pi.

Two of the most popular options are Raspbian, which is based on the Debian operating system, and Pidora, which is based on the Fedora operating system.

 What are alternatives to the Raspberry Pi?

The Raspberry Pi is not the only small computing device out there.
