Question 1: Explain two ways in which the production of electronic devices can harm the environment.

Answer: Electronic device production can harm the environment through the extraction of raw materials, which can lead to habitat destruction and pollution, and through the energy-intensive manufacturing process, which contributes to greenhouse gas emissions.

Question 2: Describe what is meant by 'e-waste' and explain why it is an environmental concern.

Answer: E-waste refers to discarded electronic devices that are no longer in use. It is an environmental concern because many electronic components contain toxic substances that can pollute soil and water if not properly recycled.

Question 3: List three sustainable practices a technology company can adopt to reduce its environmental impact.

Answer: Using renewable energy sources, designing products for longevity and easy recycling, and reducing energy consumption in data centres.

Question 4: Complete the following truth table for a logic gate: Inputs A and B, and Output O. The gate is an AND gate.

Answer: [{"A":0,"B":0,"O":0},{"A":0,"B":1,"O":0},{"A":1,"B":0,"O":0},{"A":1,"B":1,"O":1}]

Question 5: Draw a logic circuit diagram for an OR gate with two inputs.

Answer: A diagram showing two input lines entering an OR gate symbol, with a single output line. The OR gate shape is a curved shape with two inputs on the left and one output on the right.

Question 6: Sketch a design for a solar-powered outdoor Wi-Fi hotspot device. Label key features such as the solar panel, power storage, and Wi-Fi antenna.

Answer: A detailed sketch showing a compact device with a solar panel mounted on top, a battery or power storage component inside, and an antenna protruding from the body for Wi-Fi transmission.

Question 7: Describe a potential ethical dilemma related to using data from environmental sensors in public spaces.

Answer: A dilemma could involve balancing public safety benefits from monitoring environmental conditions with privacy concerns, as the sensors might collect data that could be used to track individuals or invade privacy.

Question 8: Suggest two ways in which the use of artificial intelligence (AI) can help reduce the environmental impact of computing.

Answer: AI can optimize energy usage in data centres and smart grids, and it can assist in monitoring environmental conditions to inform conservation efforts.

Question 9: Explain why it is important for technology companies to consider the environmental impact of their products and processes.

Answer: Considering environmental impact helps reduce pollution and resource depletion, supports sustainability, and aligns with ethical responsibilities towards future generations.

Question 10: Identify and explain one global initiative aimed at reducing the environmental impact of electronic waste.

Answer: The Basel Convention is a global treaty that aims to reduce the movement of hazardous waste, including e-waste, between countries and promote environmentally sound management of such waste.
