![]() It turned out to be possible to compile his kernel and use it inside the GNU userland (this was probably not trivial, but I wasn't there and don't know). He just had a kernel, it wasn't a full system either. When Linus Torvalds created his Linux kernel, he didn't create a userland. All the things outside the kernel (running as processes owned by users) are together known as the "userland". ![]() But the kernel (called "Hurd") wasn't finished. ![]() They got very far, they made a C compiler, a C library, a linker, editors, shells, all the commands you'd expect in a typical Unix shell, lots of stuff. GNU stands for "GNU's Not Unix", and it is an attempt to create a free, independent version of Unix, developed by the Free Software Foundation. There's one more thing you need to know of: GNU. If you are really interested in learning the history behind all this I recommend a film called Revolution OS, which goes into a lot of the history behind the development of this free software movement. Unix: An old Operating System which the Linux kernel loosely based on.Ubuntu: Newer Operating System based on Debian (Still in active development).Debian: Early Operating System to Ubuntu (Still in active development).Linux: Kernel (Still in active development).It is very popular because is is easy to learn without the need to use the terminal. Ubuntu is another Operating System which was released in 2004 and is based on the Debian Operating System. Note here despite many of its releases being referred to as 'Linux' this is a specific aspect which makes up the Operating System along with the text editor, compiler, debugger etc and not an Operating System in its own right.ĭebian is one of the forms of this Operating System released in the early 1990s as is one of the most popular of the many versions of Linux available today. The kernel is responsible for managing the systems resources and allocating them to applications. This kernel was used in the initial software releases by the Free Software Movement to compile a new Operating System. It was initially developed by Linus Torvalds through the 1990s. In relation to the others, the Linux kernel is Unix-like. Unix was initially written in assembly, but later developed into C. It was originally designed to be a developer station rather than application platform, but, as development progressed and different vendors got involved, Unix was added to. Unix is an Operating System developed starting in 1969.
