What is shut down (in computer networking)?

To close a program or operating system in a way that ensures that no data is lost and that the system is not corrupted. To properly shut down a computer running Microsoft Windows 2000, choose Shut Down from the Start menu. Windows 2000 then performs the following actions:

  • Closes all open files
  • Saves operating system data
  • Prepares the system to be powered off

If Windows 2000 is shut down improperly (through a power failure, for example), a utility called autochk.exe runs upon reboot to check and repair any volumes that are marked as dirty.
