Raspberry Pi is a powerful device, an independent computer, and is sold at a highly competitive and affordable price. Raspberry Pi will support you in playing games, browsing the internet, learning to program, or creating your own physical devices. In this guide you will find step by step instructions for performing all these activities. Raspberry Pi is a one-point computer; therefore, it is built on one single PCB. It will work like a computer, laptop, or smartphone. It is very small in size, like a credit card, and is powerful enough to compete with other similar devices. It can perform high functionality tasks like a computer does, but maybe not that much quicker. The Raspberry Pi boards are used worldwide in offices, classrooms, data centers, homes, self-control boats, and small factories. ¿¿The first model released for the Raspberry Pi was model B. After that, there was no stopping it and many other models have been released to provide specific features or specifications for different use cases. For example, the Zero family of Raspberry Pi, which is a micro version of the complete Raspberry Pi, has dropped certain features such as wired network port and multiple USB options to have a small layout. This is particularly useful for those who need fewer power loads.
