Was ist Linux
In fact, it is currently the most-used OS. Because it is open-source, Linux’s code is available for users to view and edit, and even contribute to. This makes it highly customisable (selecting applications, word processors, web browsers, and even core components, such as system display graphics). It was released in 1991, and was meant to be similar to Unix, an earlier operating system.
Linux is very popular because of its customisability, and the fact that it is secure and has a large support community.
