Typically, Linux is packaged in a form known as a Linux distribution (or "distro" for short) for both desktop and server use. The defining component of a Linux distribution is the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds.

SHARE Operating System SHARE Operating System The SHARE Operating System (SOS) was created in 1959 as an improvement on the General Motors GM-NAA I/O operating system, the first operating system, by the SHARE user group. The main target was to improve the sharing of programs over GM-NAA I/O. SHARE Operating System provided new methods to manage buffers and input/output devices, and, like GM-NAA I/O, allowed execution of programs written in assembly language. Initially, it worked on IBM 709 computer and its transistorized compatible successor the IBM 7090. A series of articles describing innovations in the system appears in the April, 1959, Journal of
