What Is Linux Ubuntu?
One of the most well-liked and widely utilised operating systems in the world is Linux. Almost everything runs on Linux, including supercomputers, home appliances, internet servers, phones, and tablets. Since its creation in the 1990s, Linux has been in use. It served as a free and open-source replacement for the prior industry-dominating UNIX operating system. Yet as Linux became widely accessible, UNIX's popularity waned because it was not free or open-source.

Distributions of Linux
There are various "flavours" of Linux. Distributions are the name given to these many versions of Linux (distros for short. Each distribution includes the Linux Kernel and a package management system out of the box. A database of the packages installed on the system is kept up to date by package managers.
