  The KernelThe Linuxkernel is uniqueModular in natureAllows developers to shed parts of the kernel they don’t need to useSmaller kernel is a faster kernelThe ability to scale down (or up) to meet the needs of a specific platform is a big advantage over other operating systems
• 16.
  The Operating SystemLinuxprovides powerful tools with which to write their applicationsDeveloper environments, editors and compilersLike the kernel, the operating system is also modularDevelopers 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 EnvironmentsWindowing systemand the desktop environmentThe windows, menus, and dialog boxes A lot of choices for which windowing system and desktop environment can be usedLinux allows its users to decideCannot be done in Windows, difficult to do in OS XTools and code libraries available that let application developers to more readily work with the environments
• 18.
  The ApplicationsLinux applicationdevelopers have a larger set of choices to develop their applicationWindows and OS X will not let users pick and choose the essential component applicationsFlexibility in builingDeveloper will need to decide which Linux components to use
