Linux was designed to be UNIX-compatible software that was composed entirely of open source or free software components. Linux derives much of its design principles from those established in the 1970's by UNIX. These principles include a single kernel that handles process control, file system access, networking and peripheral device access. Device drivers are integrated directly into the kernel. Today, the Linux operating system has been commercially available for over a decade and is considered the most widely available open source operating system on the market. It is distributed on a wide range of devices from cell phones to supercomputers, but it is on the server platform.
