SCADA
SCADA (Supervisory Control and Data Acquisition) is a computer system that helps monitor and control industrial equipment and processes. Think of it as a central control room where operators can see what's happening in a factory, power plant, or water treatment facility through computer screens. It's like a dashboard that shows information from various machines and allows operators to make adjustments. This technology is essential in industries like manufacturing, utilities, oil and gas, and water treatment. Similar systems might be called Industrial Control Systems (ICS) or Process Control Systems (PCS).
