Operating systems linux Presentation Transcript

  • 1. Operating Systems (Linux)
    Morgan Williams
    February 28, 2011
  • 2. Operating Systems (Linux)
    A free, open-source operating system for PCs, servers, and other types of computers
    Owns a small percentage of the PC operating system market
    Popular with technically inclined individuals, some corporations
  • 3. The Birth of Linux
    Linus Torvalds, 1991
    Initially created as a hobby
    Built the core of the Linux operating system
    Known as the kernel
    In many ways it is still at the beginning of its potential
    Governments deploying Linux
    Commissioning their own versions of Linux
  • 4. Essential Information
    Can be installed on a variety of computer hardware
    “From wristwatches to supercomputers”
    Linux’ capabilities
    Leading server operating system, runs the 10 fastest supercomputers in the world
  • 5.
  • 6. Essential Information
    Open-source software
    Users can manipulate the source code, making Linux highly configurable
    Challenged by Windows and Mac
    Not 100% compatible with the software
    Challenging to collaborate
  • 7. Essential Information
    Powerful, free UNIX-like operating system for desktop PCs
    Multitasking, multi-user computer operating system
    Command-line operating system or through a graphical desktop interface such as GNOME
  • 8. Essential Information
    Used on computers ranging from small personal computers to large mainframe systems
    Available for free to users under a General Public License arrangement
    Vendors offer commercial (not free) versions
    More features and user support
  • 9. Essential Information
    Many versions (distributions, distros) designed by the user community
    Open source with many more customized versions than Microsoft Windows or Mac OS
    Hundreds of versions of Linux
    Hundreds of thousands of unique Linux setups
  • 10. Essential Information
    Developed collaboratively
    No one company is solely responsible for its development or ongoing support
    Companies in the Linux economy share take part in research and development
    Commercial and private developers contribute other software
    Resulted in software innovation
  • 11. Essential Information
    Develop utilities, applications and enhancements to the operating system
    Linux Ubuntu
    Free open-source applications
    Includes all regular software plus several accessories and more than a dozen games
    Linux users think it is the best Operating System
  • 12.
  • 13. Parts of the Linux Operating System
    The Kernel
    The Operating System
    The Environments
    The Applications
    The Distributions
  • 14. The Kernel
    The Linux kernel is unique
    Modular in nature
    Allows developers to shed parts of the kernel they don’t need to use
    Smaller kernel is a faster kernel
    The ability to scale down (or up) to meet the needs of a specific platform is a big advantage over other operating systems
  • 15.
  • 16. The Operating System
    Linux provides powerful tools with which to write their applications
    Developer environments, editors and compilers
    Like the kernel, the operating system is also modular
    Developers can pick and choose the operating tools to provide users and developers with a new flavor of Linux designed to meet specific tasks
  • 17. The Environments
    Windowing system and the desktop environment
    The windows, menus, and dialog boxes
    A lot of choices for which windowing system and desktop environment can be used
    Linux allows its users to decide
    Cannot be done in Windows, difficult to do in OS X
    Tools and code libraries available that let application developers to more readily work with the environments
  • 18. The Applications
    Linux application developers have a larger set of choices to develop their application
    Windows and OS X will not let users pick and choose the essential component applications
    Flexibility in builing
    Developer will need to decide which Linux components to use
  • 19. The Distributions
    Highest layer of the Linux operating system
    Maintained by private individuals and commercial entities
    Offer mature application management systems
    Allow users to search, find, and install new applications
  • 20. The Future of Linux
    Showing up on mobile Internet devices
    Embedded devices such as smartphones and PDAs as well as netbook devices
    Twitter, Linked In, YouTube, and Google
    As new web services arrive in the future, Linux will increasingly be the platform that drives these new technologies
