What is Linux?

Linux is open source operating system developed in 1991. Linux Torvalds introduced this operating system in 1991 at the university of Helsinki.

15. User Case

Unix is used on servers, Workstations and PCs, whereas Linux is used everywhere from server, PCs, smartphones, tablets to mainframes.
