Explanation:
SCADA stands for supervisory control and data acquisition. It refers to industrial control systems (ICS): computer systems that monitor and control industrial, infrastructure, or facility-based processes. It 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. Hardware gathers and feeds data into a computer system that has SCADA software installed. The computer then processes this data and presents it in a timely manner. This system also records and logs all events into a file stored on a hard disk or sends them to a printer. It warns when conditions become hazardous by sounding alarms.
