A small why and how-to Linux


    So What is Linux?

    There are many answers to this question! Much is written about how Linus Torvalds developed Linux and what happened then.
    The Linux system is a Unix-clone. A bare Linux system is just the Operating system kernel, drivers for hardware, file system etc. and quite a number of system programs. It would take less than 100Mb to install and you have a multiuser, networking, character / terminal based computer system and you could run it on an old 386 pc.
    But in the Linux concept we include a number of other functions and programs also developed in the Open Source community. So when we add the Free X11 system, a Window manager and some other programs, then we have a complete modern and nice desktop computer system. Linux software has matured the last couple of years and there are a lot of quality programs around.

    Linux is NOT ONE system, it is a modular system that becomes different things depending on how you configure it. You might already be running it on your TV set-top box without knowing it.
