  2. Operating Systems • Two different types of programs are executed on a computer: • Applications • Operating system (OS) software • User Interface: An application program that allows the user to interact with the OS and other application programs • GUI • Terminal

  3. Operating Systems (continued) Figure 1-1: The role of operating system software

  6. The Linux Operating System • OS used to run a variety of applications on a variety of different hardware • Has the ability to manage thousands of tasks at the same time • Allows multiple users to access the system simultaneously • Multiuser and multitasking OS

  7. Keeping SuperUser under control • There is one administrative account that has “all power”. It is called root • This account can make changes to the operating system file system, install and upgrade software • This account can also delete and change critical system files which can potentially disable the system • Linux is literal, and usually results are immediate • Use the root account with care! • You can access root privileges without being logged in a sthe root account by running the command at a terminal prompt su • If you attempt to make changes to system services and configuration when using the Graphical User Interface, you will be challenged for the password for the user root.

  10. Linux Advantages: Ease of Obtaining Support • Linux documentation can be found on the Internet • Frequently Asked Questions (FAQs) • HOWTO documents • Linux Newsgroups • Linux User Group (LUG): Open forum of Linux users who discuss and assist each other in using and modifying the Linux OS
