Debian is a set of free operating systems (OS) designed for your computer. An operating system is a collection of basic programs and tools that make a computer run. Debian uses the Linux kernel (the most important part of the operating system), but most of the basic tools come from the GNU project, so we call it GNU/Linux. Debian GNU/Linux is not just an operating system, it also contains more than 18,733 packages, some of which have been compiled and packaged in an easy to install format. Debian was first created in 1993 by Ian Murdock. It can be regarded as the Linux system that most closely follows the GNU specification. The Debian system is divided into three version branches: stable, testing, and unstable. As of May 2005, the specific versions of the three versions of the branch are: Woody, Sarge and Sid. Among them, unstable is the latest test version, including the latest software package, but there are also relatively many bugs, suitable for desktop users. The testing version has been tested in unstable, relatively stable, and supports many new technologies (such as SMP, etc.). While Woody is generally only used for servers, most of the above packages are outdated, but stability and security are very high. Why are so many users obsessed with Debian (including the author)? Apt-get /dpkg is one of the reasons. Dpkg is a unique package management tool for the Debian series, which is hailed as the most powerful of all Linux package management tools (such as RPM)! With apt-get, it's extremely easy to install, upgrade, delete, and manage software on Debian. Many Debian users are joking that Debian is lazy because they simply click on "apt-get upgrade & amp-get update" and all the software on the machine will be updated automatically... : Follow the GNU specification, 100% free, excellent network and community resources, powerful apt-get Disadvantages: Installation is relatively difficult, stable branch software is extremely outdated Package management system: APT (DEB) is relatively free in Linux distributions One. It is continuously developed and maintained by thousands of volunteers located around the world. It does not belong to any commercial company and is entirely owned by the open source community. Is a set of free operating systems (OS) designed for your computer. An operating system is a collection of basic programs and tools that make a computer run. Debian uses the Linux kernel (the most important part of the operating system), but most of the basic tools come from the GNU project, so we called GNU/Linux Sarge. After more than three years of development, it was officially released on June 6, 2005. Replace Woody as the latest Stable. The code of the testing is changed to etch, and the code of the unstable is still sid. Debian stopped supporting the old Stable version of Woody at the end of June 2006. The distribution, code-named Sarge in Debian, has been certified by the Open Source Development Lab (OSDL) as a carrier-grade Linux (CGL) specification. Debian GNU/Linux is not just an operating system, it also contains more than 15,490 packages, which are compiled software and packaged into an easy-to-install format.
