The correct answer is: B. supervisory control and data acquisition
SCADA is a system that uses computers and telecommunications to monitor and control industrial processes. It is used in a variety of industries, including power generation, water and wastewater treatment, oil and gas production, and transportation.
SCADA systems typically consist of three main components:
- Sensors that collect data from the process
- Controllers that use the data to make decisions about how to control the process
- Communication links that connect the sensors and controllers to a central computer
The central computer collects data from the sensors, displays it on a screen, and sends commands to the controllers. The controllers use the commands to control the process.
SCADA systems can be used to monitor and control a wide variety of processes, including:
- Power generation
- Water and wastewater treatment
- Oil and gas production
- Transportation
- Mining
- Manufacturing
SCADA systems can provide a number of benefits, including:
- Improved efficiency by allowing operators to monitor and control processes remotely
- Reduced costs by eliminating the need for on-site personnel
- Improved safety by providing operators with real-time information about the process
- Increased reliability by allowing operators to quickly identify and respond to problems
SCADA systems are a critical part of many industrial processes. They provide operators with the information and control they need to keep processes running safely and efficiently.
The other options are incorrect because they do not accurately reflect the full form of SCADA.
