SCADA (supervisory control and data acquisition) is a category of
software application program for process control, the gathering of
data in real time from remote locations in order to control equipment
and conditions. SCADA is used in power plants as well as in oil and
gas refining, telecommunications, transportation, and water and waste
control. 

SCADA systems include hardware and software components. The hardware
gathers and feeds data into a computer that has SCADA software
installed. The computer then processes this data and presents it in a
timely manner. SCADA also records and logs all events into a file
stored on a hard disk or sends them to a printer. SCADA warns when
conditions become hazardous by sounding alarms.
