    • Operating Systems (Linux)
      Morgan Williams
      February 28, 2011
    • 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
    • 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
    • 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
    • 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
    • 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
    • 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
    • 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
    • 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
    • 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
    • Parts of the Linux Operating System
      The Kernel
      The Operating System
      The Environments
      The Applications
      The Distributions
    • 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
    • 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
    • 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
    • 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
    • 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
    • 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
