GLOSSARY
- Operating system: set of programs that manages the use of the computer hardware resources by the launched applications. This includes memory and hard disk storage resources, processor computing resources, communication resources to external devices or via the network. The operating system either accepts or denies these requests, and then reserves the resources in question to prevent their use from interfering with other requests from other software.

- Linux Debian version: GNU / Linux or Linux is an operating system that combines essential elements of the GNU project and the Linux kernel. It is available in the form of various distributions. Debian is the name of a non-profit distribution that relies exclusively on open source software and is developed and maintained by the Debian association. One particularity is that it is managed by a community. The Debian version for Raspberry Pi mentioned in the video can be downloaded from the Raspberry Foundation website, either via an installer (NOOBS) or via an image of the distribution (raspbian).
- Connector: An element that provides the physical connection to establish an electrical link or data transmission. In computer science, this term can be used to designate a port (even if the connector also refers to the plug of the connection).
- GPIO: General Purpose Input / Output I / O port that allows an electronic card (microcontroller card or motherboard) to communicate with any device. They are programmable, allowing them to adapt to a wide variety of devices, provided they write a driver.
