This article mainly explains "what are the Ubuntu software components". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn what Ubuntu software components are.

Ubuntu's software management system is the same as Debian's, using the APT management package, while there is also a graphical user interface Synaptic (Synaptic package Manager) available. It divides all software into four categories, called "component", to reflect different licenses and available support levels. Under normal circumstances, software from main (official support) is installed to meet the basic requirements of most computer users, as is software from restricted ("copyright restriction"), which is important for system availability.

The main component contains only packages that meet the Ubuntu license requirements and are available for support from the Ubuntu team. It tries to include everything you need to use the Linux system on a daily basis. The package in this component ensures technical support and timely security upgrades. The software in this component must be free software that meets the Ubuntu copyright requirements (Ubuntu license requirements), which are roughly the same as the Debian Free Software guidelines (Debian Free Software Guidelines).

Restricted components contain software that is supported by Ubuntu developers because of their importance, but they do not have an appropriate free license and therefore cannot be included in main. This includes video card drivers that are only available in binary form. Because the source code is not available to Ubuntu developers, the level of support is limited compared to main.

Universe (Community maintenance) components contain a wide range of software, which may or may not be limited by licenses, but are not supported by the Ubuntu team. This allows users to install a wide variety of programs using Ubuntu's software package management system while isolating them from the packages supported in main and restricted.

* is a multiverse ("non-free") component that includes packages that do not meet free software requirements and are not supported.

It can be summarized as follows:

Free software non-free software

Official support for Main Restricted

Not officially supported by Universe Multiverse

Because after the release of the new version of Ubuntu, the package library of this version will be frozen and only security updates will be provided, so the government has launched a follow-up support program called Ubuntu Backports, which allows users to obtain the * version of the software.

In short, in Ubuntu, the installation of software is mostly done through the apt-get instruction or the Synaptic tool, where all officially supplied software can be found (not necessarily supported), which is very different from the Microsoft Windows operating system. In Windows, users who want to install software have to buy their own installation file or execution file (extension .exe) or download it on the network, and look for it one by one, while in Ubuntu, they can complete a large number of software installation at once, because no matter the apt-get command or Synaptic, they can search and install a large number of software in a single time.

Thank you for your reading, the above is the content of "what are the Ubuntu software components?" after the study of this article, I believe you have a deeper understanding of what Ubuntu software components have, and the specific use needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
