    What Is Linux And Kubuntu ?

    What Is Linux And Kubuntu ?
    Linux Information .

    What is Linux ? Linux is a Unix clone written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It aims towards POSIX compliance. It has all the features you would expect in a modern fully-fledged Unix, including true multitasking, virtual memory, shared libraries, demand loading, shared copy-on-write executable, and more... Linux is an open source operating system. Open source means it is developed by nonprofit making organizations and individuals all over the world. They collaborate and share their work. Anybody can view others work and modify it. After modification he must in-turn open it for everybody. By this way great bug-fixing and development of Linux has occurred in past years. It is a modern OS with many features that are superior to windows. Another plus point is that it is completely free. You can buy a Jewel Box distribution at a nominal price or get a complete box-packaged of-the-shelf distribution complete with manuals, tech support and much more software. The LSB project (Linux Standard Base) ensures compatibility among different versions. There is also standard Internationalization effort (i18n) through Free Standard Group. They have come up with OpenI18n Standard .

    Kubuntu is a Linux operating system built by a worldwide team of expert developers. It contains all the applications you need: a web browser, office suite, media apps, instant messaging and much more. It is an open-source alternative to Windows and Office.

    Linux is made up of following Parts/components -

    1. A Linux Kernel - The heart/brain of OS. Now in Version 2.6.31.

    2. X11R7 - The free X-Windows GUI system.

    3. KDE / Gnome - K Desktop Environment and Gnome Desktop Environment. The GUI operating environments for Linux. XFCE is a new lightweight but feature filled Desktop Environment.

    4. Qt / GTK+- Qt is a widget library of programming objects - pre built C++ components. It is cross platform , means you can simultaneously develop your application on Linux, Mac, and Windows. KDE and many other applications are based on it. Many considered it as the most important piece of Linux programming today. GTK+ for Gnome is a rival.

    5. GCC - The GNU C++ and other compiler ( GCC features C, C++, Fortran 77, Objective C, Java and Ada 95 compilers) collection.

    6. GLibC - The GNU C++ library .

    7. ALSA / PulseAudio - ALSA - Advanced Linux Sound Architecture. PulseAudio is a sound server for POSIX and Win32 systems.

    8. Now a days, Java and Mono (.Net implementation on Linux) are also considered mandatory by many.

    9. You will also get lots of free software depending on your choosing Linux as a Server, or Desktop. These are listed below...

    If you choose Linux as a Server you can save thousands of dollars. As its roots are in UNIX, Linux has built-in support for File, Print, Application and Terminal Server. The money saved is better spend on extra hardware. As a server (in latest kernel 2.6.x series) even a basic installation can support 64 GB of RAM, 8 Way SMP systems, up to 16 Ethernet cards, 10 IDE controllers, and multiple IO-APICs. It can access terabytes of file system/storage, can now handle an amazing number of users and groups - about 4.2 billion of users. Full 64-bit support is available for Intel/AMD CPU. Linux is a pre-emptive multitasking, multithreaded and GUI based networked operating system. As its heritage in Unix, it has built-in client-server architecture with full TCP/IP support. The X-Windows system helps running GUI based apps remotely on a client machine (even if the machine is half way around the world!). Most network hardware are smoothly supported (Like LAN Ethernet cards, Hubs, etc). The 2.6.x kernel series has more server features.

    The main benefits of choosing Linux as a Server are listed below......

    Lots of very powerful open-source software are available for free or at negligible cost if you choose Linux as a Server. Like.......

    1)Web Server : Like Apache a Web Server (With GUI based configuration tool like ApacheConf) which powers over 50% of all web sites, Zeus is also a powerful Web Server.

      Well, in Mave the kernel version is 2.6.35-something already...

      8. Now a days, Java and Mono (.Net implementation on Linux) are also considered mandatory by many.
      Not by us and many other informed users / forumers that know about the thread mono represents to Linux if used abundantly (or at all).
      Multibooting: Kubuntu Noble 24.04
      Before: Jammy 22.04, Focal 20.04, Precise 12.04 Xenial 16.04 and Bionic 18.04
