IB Computer Science 7. Control Questionbank

(d) Explain the potential challenges of implementing an automated control system in a warehouse.

(e) Evaluate the benefits of using an automated control system in a warehouse compared to manual control.

A self-driving car relies on a series of lasers and cameras that combine with high definition maps to give a three-dimensional (3D) view of the environment. Rules are programmed into the system so that the car drives at an optimum speed, keeps a safe distance from any vehicle in front, uses fuel economically and follows the traffic regulations.

(a) Outline the need for high definition maps held in memory.

(b) Outline how analysing successive 3D images in memory helps the car to drive safely.

(c) Outline the time and memory needs of 3D visualization in this situation.

(d) Discuss the social implications of self-driving cars.

Outline one feature of autonomous agents.

An oil and gas company has a networked computer system for use by their employees in the Head Office. The company also uses a computer control system to monitor an oil/gas pipeline: flow and pressure sensors collect data, the processor checks the readings against safe limits, and output transducers (for example, alarms or valve actuators) are activated when necessary.

(a) Identify one hardware security measure that will ensure that confidential data from the Head Office cannot be accessed.

(b) Identify one software security measure that will ensure that confidential data from the Head Office cannot be accessed.

(c) Identify one network security measure.

(d) Explain the environmental benefit of using a computer control system to monitor the pipeline.

A smart city project is being developed to manage traffic flow in real-time using intelligent traffic lights. The system aims to reduce congestion and improve traffic efficiency by adjusting the timing of traffic lights based on real-time traffic data.

(a) Explain the role of sensors in the intelligent traffic light system.

(b) Describe how actuators are utilized in the intelligent traffic light system to manage traffic flow.

(c) Discuss the importance of feedback loops in the intelligent traffic light system.

(d) Explain the potential challenges of implementing an intelligent traffic light system in a smart city.

(e) Explain the relationship between sensors, output transducers and processor in this situation.

(f) Construct a system flowchart to represent the pipeline monitoring process described above.

(e) Evaluate the benefits of using an intelligent traffic light system compared to traditional traffic light systems.
