Unix, Linux, and variants
Unix, which is not an acronym, was developed in the late 1960's by many of the same people who helped create the C programming language. Today, however, Unix is not just the work of a couple of programmers. Other organizations, institutes, and individuals contributed significant additions to the modern Unix system.

Developed by Linus Torvalds and further elaborated by a number of developers throughout the world, Linux (lee'nuhks/ or /li'nuks/,_not_/li:'nuhks) is a freely available multitasking and multiuser operating system. From the outset, Linux was placed under General Public License (GPL). The system can be distributed, used, and expanded free of charge. In this way, developers have access to all the source codes, thus being able to integrate new functions or to find and eliminate programming bugs quickly. Thereby drivers for new adapters (SCSI controller, graphics cards, etc.) can be integrated very rapidly.
