Peeling back a typical open source application you are likely to find the window managers Gnome or KDE. Even likelier is that it is all running on a Linux operating system. And at the core of it all is the kernel. This is the distinguished Linux kernel, connecting your collection of software to the halls of your hardware. To say a program is Linux based is really just simply saying that it uses the Linux kernel. But what do they actually do?
Formerly known as distributions, what operating systems that use the Linux kernel do is offer a buffet of open source software as opposed to actually cultivating them. Well known systems like Ubuntu and Red Hat Enterprise Linux are perfect examples. The open source programs and distributions work hand in hand.
For a detailed example, think about the above mentioned Gnome window manger. It is the desktop environment of most the popular distributions such as Ubuntu and Red Hat. These distributions are free to manipulate Gnome by including or omitting certain applications to reach its intended purpose. It can be said then that essentially Gnome becomes the operating system since it is the interface.
But, a distribution like Ubunutu will do without the Gnome web browser Epiphany and support Firefox. Instead of supporting the Gnome office suite, it institutes the widely used OpenOffice program. Users are free to choose among a variety of distributions that will house an array of open source software.
It is additionally the distributions purpose to make sure the applications in its repositories operate among each other flawlessly. Because all of the alternating parts are independently developed, they contain differing directions and objectives. The distributions then are tweaked to keep all systems moving smoothly.
These Linux distributions act like the shepherd of open source computing, herding a diverse set of software sheep into one powerful digital herd.
