ASL STEM

Definition

The operator's station of a mainframe. In times past, this was a privileged location that conveyed godlike powers to anyone with fingers on its keys. Under Unix and other modern time-sharing operating systems, such privileges are guarded by passwords instead, and the console is just the tty the system was booted from. Some of the mystique remains, however, and it is traditional for sysadmins to post urgent messages to all users from the console (on Unix, /dev/console).
