The UNIX operating system, which was developed at the AT & T Bell Labs in the late 1960s, was adopted by certain organizations throughout time and ceased to be free software; Linus Torvald, was a student at the University of Helsinki in 1991, wrote a UNIX-based operating system with many improvements/innovations and named it Linus. Linus spread over the Internet in a very short time and was developed by many programmers. In time, different organizations have developed different versions using the kernel of this operating system and the common name “Linux” has been used.
