What is Linux?

Linux, which has the penguin ‘Tux’ as both a logo and a mascot, is the core that is used by Linux-based operating systems. Unlike the Windows and OS X for Mac operating systems, Linux-based operating systems are based on open source. Many Linux systems are offered free of charge, and it is possible to read and even be involved in the development of source code for Linux if you so wish!

The first version of Linux was launched on the internet in September 1991, and since then thousands of developers from all over the world have taken part in the project. Linux is used in everything from personal computers to supercomputers. There are also repeated mini-versions for small systems, such as mobile phones and camcorders. For example, Linux is used as the core of the Android mobile operating system.

After initially being developed by enthusiasts, Linux has been supported by companies such as IBM and HP. This has caused operating systems such as Unix and Microsoft Windows to lose market share to Linux in the server market. Supporters and analysts have attributed much of the credit for this success story to supplier independence, low realisation costs, security, access to source code and stability.
