SCADA
SCADA (Supervisory Control and Data Acquisition) is a computer system that helps monitor and control large industrial operations. Think of it like a central dashboard that lets operators keep an eye on equipment, processes, and facilities from one place. It's commonly used in factories, power plants, water treatment facilities, and oil/gas operations. SCADA is similar to other industrial control systems, but it's specifically designed for large-scale processes that can be spread across multiple sites. It's the technology that lets a small team monitor and control complex operations that would otherwise require many more people to manage.
