Troubleshooting Common Operating System Problems.

1. Incompatibility – application hardware/software and files need to be compatible with the computer’s OS.

2. File corruption – files can become corrupt as a result of power failure, turning off the computer without properly shutting it down, a virus, resource conflicts, outdated drivers, bad sectors or lost clusters on the hard drive, bad hardware/software installation and so on.

3. Disk Crashes – if your system is unstable, programs and even the OS shut down unexpectedly and you receive error messages/troubleshooting when you try to use the OS and applications.

III. Operating system can be categorized by a number of characteristics: Technology, Usage, and Licensing. Dictate the following text to your group mate. Check it together.
