What Is Linux?

Linux is the core, or kernel, of a free operating system first developed and released to the world by Linus Benedict Torvalds in 1991. Torvalds, then a graduate student at the University of Helsinki, Finland, is now a Fellow at the Linux Foundation (www.linuxfoundation.org/). He is an engineer and previously worked for the CPU design and fabrication company Transmeta, Inc. before leaving in 2003 to work for Open Source Development Labs (ODSL), a consortium created by many high-tech companies to support Linux development and which has enabled him to focus on the Linux kernel full time. Fortunately for all Linux users, Torvalds chose to distribute Linux under a free software license named the GNU General Public License (GPL).
