What is a centralised control system?

• A system where decision-making is distributed among multiple units.

• A type of control system where all decision-making and control processes are managed by a single central unit.

• A system with no central management, relying on individual components to function independently.

• A control system where each component operates based on local sensors without a central unit.

What is the role of the central unit in a centralised control system?

• To distribute tasks among various interconnected units.

• To monitor and control the operation of the entire system.

• To act as a backup in case other systems fail.

• To decentralize control and improve system flexibility.

Which of the following is a limitation of centralised control systems compared to distributed systems?

• Improved scalability

• Simpler design and communication structure

• Higher fault tolerance

• Limited flexibility

In which environments are centralised control systems commonly used?

• Environments where individual control is preferred over unified control.

• Environments where unified, cohesive control is necessary and central oversight is beneficial.

• Environments that require decentralized control for better performance.

• Environments where systems need to operate independently without central oversight.

What does the control system in a heating system use to regulate the temperature?

• A sensor to detect the distance traveled

• A thermostat to regulate the temperature of a room

• A motor to manage the opening and closing of doors

• A screen to display the amount of fare

How does the control system in GPS systems function?

• It manages the reception and processing of radio signals.

• It manages the reception and processing of satellite signals.

• It manages the reception and processing of internet signals.

• It manages the reception and processing of sound waves.

What is the role of a control system in traffic lights?

• To control the speed of vehicles

• To play traffic announcements

• To manage the timing of the lights and the flow of traffic

• To count the number of vehicles

What is the role of sensors in a control system?

• To provide power to the system

• To measure various physical variables such as temperature, pressure, position, and speed

• To convert digital signals into physical actions

• To perform calculations and make decisions

What do Analog-to-Digital Converters (ADCs) do?

• Convert digital signals into analog signals

• Measure physical variables like temperature and pressure

• Convert analog signals from sensors into digital signals that can be processed by the microprocessor

• Send control signals to actuators

What is the function of a microprocessor in a control system?

• To convert analog signals into digital form

• To measure physical variables

• To control the power supply of the system

• To perform calculations and make decisions based on input signals
