6.1 Automated Systems Cambridge IGCSE 0478

What is the primary role of a sensor in an automated system?

• To detect changes in the environment and provide input to the system.

• To process information and make decisions.

• To control physical components such as motors.

• To generate electrical power for the system.

In an automated heating system, what is the function of a microprocessor?

• To process temperature data and decide when to turn the heating on or off.

• To physically increase or decrease the room temperature.

• To detect temperature changes in the room.

• To store historical temperature data for analysis.

Which of the following is an example of an actuator in an automated system?

• A motor that moves a robotic arm.

• A temperature sensor measuring room temperature.

• A microprocessor deciding to turn on a fan.

• A database storing system logs.

What is an advantage of using automated systems in manufacturing?

• Increased efficiency and precision in production.

• Reduced initial setup costs.

• Elimination of all system failures.

• Complete removal of human supervision.

What is a disadvantage of automated systems?

• High initial setup costs.

• Increased human errors.

• Reduced production speed.

• Inability to work in hazardous environments.

Which of the following industries commonly use automated systems?

• Agriculture, transport, and manufacturing.

• Cooking, social media, and literature.

• Handcrafted jewelry, art, and music.

• Traditional farming, local markets, and tourism.

Why do automated systems improve safety in industries such as mining?

• They can perform dangerous tasks, reducing human risk.

• They require fewer system updates.

• They eliminate all operational costs.

• They increase the need for human supervision.

Which component of an automated system is responsible for executing actions?

• Actuator

• Sensor

• Microprocessor

• Compiler

How does an automated irrigation system benefit agriculture?

• It reduces the need for manual labor and ensures efficient water use.

• It eliminates the need for fertilizers.

• It removes the need for monitoring plant growth.

• It operates without sensors or microprocessors.

What is a potential risk of relying too much on automated systems?

• Dependence on technology, which may fail or be vulnerable to cyber attacks.

• Increased manual labor costs.

• Reduced efficiency in production.
