Linux is an operating system that was first created at the University of Helsinki in Finland by a young student named Linus Torvalds. At this time the student was working on a UNIX system that was running on an expensive platform. Because of his low budget and his need to work at home, he decides to create a copy of UNIX system and was able to run it on a less expensive platform like a IBM PC. He began his work in 1991 when he released version 0.02 and worked steadily until 1994 when version 1.0 of the Linux Kernel was released.
