SCADA
SCADA (Supervisory Control and Data Acquisition) is like a central control system that helps monitor and control large facilities such as power plants, factories, or utility networks. Think of it as a high-tech control room where operators can see everything happening in their facility on computer screens and control equipment remotely. It's similar to how a smart home system lets you control lights and temperature, but on a much larger industrial scale. Companies use SCADA systems to keep their operations running smoothly, ensure safety, and quickly respond to any problems that might arise.
