Linux is a UNIX-like open-source operating system and was the original creation of Linus Torvalds from Helsinki, Finland in 1991. He wrote the first kernel, the underlying program interfacing and running the computer hardware. Torvalds invited programmers from around the world to comment on and to improve his code. This is one of the key ideas behind the success of Linux. With the world as your laboratory, the number of testers and developers is nearly endless. It is because of this resource that Linux is constantly evolving and improving.

With the Linux source code being freely available, several companies have developed different distributions of Linux. A distribution is a complete system. The key component is the Linux kernel. Other utilities, services, and various applications can be included as well, depending on the distribution and the intended use. There is no standard distribution. Each of the many distributions available has unique advantages.

IBM was early to recognize the value of Linux, investing in Linux-related product development, forming alliances with key Linux distributors, contributing to the open-source community, and aggressively supporting the platform. IBM believes this investment will benefit its customers as they continue to exploit Linux for their IT infrastructures and e-business applications.
