Linux
Linux (also known as GNU/Linux) is a computer operating system. It is one of the most prominent examples of free software and of open source development; unlike proprietary operating systems such as Windows or Mac OS, all of its underlying source code is available to the public for anyone to freely use, modify, and redistribute.
Initially, Linux was primarily developed and used by individual enthusiasts. Since then, Linux has gained the support of major corporations such as IBM, Sun Microsystems, Hewlett-Packard, and Novell for use in servers and is gaining popularity in the desktop market[1]. It is used in systems ranging from the common personal computer to supercomputers and embedded systems such as mobile phones and personal video recorders. Proponents and analysts attribute its success to its vendor independence (the opposite of vendor lock-in), low cost, security, and reliability].
