Debian Versions
The main Debian versions are divided into three branches:
- Stable: This is the main release recommended for servers and workstations where reliability is critical. It is updated infrequently, with critical fixes and security updates.
- Testing: Contains packages that will soon be included in the next stable release. This branch is suitable for users who want newer software versions while maintaining relative stability.
- Unstable: Also known as "Sid," contains the latest packages but may be less stable and is intended for developers and testers.
Installing Debian
The installation process of Debian is quite straightforward and intuitive. First, you need to download the installation disk image from the official project website. Versions are available for various media, including DVD images, network installations, and even minimal versions for advanced users. After downloading the image, you should write it to a USB drive or disc, boot from the media, and follow the installer instructions. During installation, users can select desired components, install a graphical environment, and configure system settings.
