A Debian ISO is a file image of a Debian operating system that can be written to a USB drive or DVD and used to install Debian on a computer. It contains all the necessary files and programs to install Debian, including the kernel, essential packages, and a graphical installer.
Debian ISOs are available for a variety of architectures, including 32-bit and 64-bit x86, ARM, and PowerPC. They are also available in different flavors, including the stable release, the testing release, and the unstable release. The stable release is the most widely used and is recommended for most users. The testing release is more up-to-date than the stable release but may be less stable. The unstable release is the most up-to-date but may be unstable.
