Basics Raspberry Pi

The Raspberry Pi was originally designed for educational purposes to use in schools and universities, and to make class and study more interesting.
Unfortunately, the practical use of the Raspberry Pi or a comparable single-board computer in Germany, Austria and Switzerland is still in its infancy. Listening to the topic, you will find only a few examples showing the use of the Raspberry Pi in school, in education or in study.
The following tasks and exercises should help a little here. They are suitable for self-study or as a source for teachers and faculty to build their own Raspberry Pi workshop. The tasks also include exemplary ready-made solutions.
A Single-board computer the size of a bank card, originally developed as a budget system for teaching computer science, subsequently received much wider application and popularity than its authors expected.
Released several generations of raspberries. All models have a system on a chip (SoC) Broadcom with an integrated ARM compatible central processing unit (CPU) and a graphics processor on a chip (GPU).
The processor speed ranges from 700 MHz to 1.4 GHz for the Pi 3 B + model; internal memory - from 256 MB to 1 GB. Secure Digital (SD) cards are used to store the operating system. The boards have one to four USB ports. For video output, HDMI and composite video are supported with a standard 3.5 mm audio output jack. The output at the lower level is provided by several GPIO pins that support common protocols such as I²C. B-models have an Ethernet port, and Pi 3 and Pi Zero W have built-in Wi-Fi 802.11n and Bluetooth. Prices range from 5 to 35 dollars.

1. Getting Started: Tasks and Exercises with Raspberry Pi
The following tasks and exercises are suitable for beginners who have not yet come into contact with the Raspberry Pi. The solutions are also interesting for those who already know the Raspberry Pi and have worked with it. The solutions are part of standard tasks that have to be done around the Raspberry Pi every now and then.

2. Computer Technology: Tasks and Exercises with the Raspberry Pi
The following tasks and exercises are suitable for beginners who have already made their first attempts with the Raspberry Pi and just want to learn more about the system and hardware.
The solutions are interesting for those who already know the Raspberry Pi and therefore want to work more intensively.
The solutions relate to questions that arise through the use of the system and specific tasks. In principle, the presented solutions can also be used on other systems.
3. Network Technology: Tasks and Exercises with Raspberry Pi
The following tasks and exercises are suitable for beginners who have already made their first attempts with the Raspberry Pi and want to or should try applications on a local network.
The solutions are also interesting for those who already know the Raspberry Pi and therefore want to work more intensively.
The solutions relate to questions that arise on concrete tasks in a network.
