What does SCADA stand for?

The term SCADA stands for Supervisory Control and Data Acquisition. This is a crucial system used in industrial and infrastructure applications to monitor and control processes. SCADA systems allow for real-time data collection and management from various remote locations, enabling operators to oversee and direct operations more effectively. The "Supervisory" aspect indicates that the system allows for oversight of the processes, while "Control" refers to the capability to manage the operations, and "Data Acquisition" pertains to gathering and storing data from the field devices.

This combination ensures that operators can not only monitor system performance but also respond to changes or emergencies swiftly, improving efficiency and safety in various industrial settings. The other choices either describe different concepts or are not recognized terminology widely associated with SCADA systems, reinforcing why "Supervisory Control and Data Acquisition" is the correct and established definition.
