Question 1: Explain how the production of electronic devices can impact the environment. Provide at least two specific examples.

Answer: The production of electronic devices can lead to environmental damage through the extraction of raw materials like rare metals, which can cause habitat destruction, and through energy-intensive manufacturing processes that increase carbon emissions.

Question 2: Describe an ethical issue related to e-waste disposal. Why is this a concern for society?

Answer: E-waste disposal raises ethical concerns because hazardous materials from discarded electronics can pollute land and water sources, harming health and the environment. Proper disposal and recycling are necessary to prevent these issues.

Question 3: Complete the truth table for a AND gate with two inputs, A and B. The outputs are stored in a column labeled 'Output'.

Answer: A | B | Output ---|---|-------- 0 | 0 | 0 0 | 1 | 0 1 | 0 | 0 1 | 1 | 1

Question 4: Draw a logic circuit that represents the following: An AND gate and a NOT gate connected so that the output of the AND gate feeds into the NOT gate. Label the gates clearly.

Answer: A correct sketch would show two inputs feeding into an AND gate; the output of the AND gate then connects to the input of a NOT gate. The final output is the negation of the AND result.

Question 5: Identify one way in which companies can improve their environmental sustainability when designing new computing products.

Answer: Companies can use recyclable materials in their products or design devices that are easier to repair and upgrade to extend their lifespan and reduce waste.

Question 6: Discuss the ethical responsibilities of software developers in reducing the environmental impact of their applications.

Answer: Software developers have a responsibility to write energy-efficient code to minimize power consumption, optimize resource usage, and promote sustainable practices in the development and deployment of applications.

Question 7: Sketch a simple diagram showing a renewable energy source that could power data centres sustainably. Label the main components.

Answer: The sketch should include a renewable energy source like a solar panel or wind turbine connected to a data centre. Labels should identify the renewable source, the connection, and the data centre.

Question 8: Explain why it is important for technology companies to consider environmental ethics when developing new products.

Answer: Considering environmental ethics ensures that companies minimize harm to the environment, comply with laws, and promote a sustainable future, which can also improve their reputation and customer trust.

Question 9: Describe a scenario where the disposal of electronic waste could lead to ethical issues in a developing country.

Answer: Electronic waste sent from developed countries to developing countries for disposal can cause health problems due to toxic substances, often without proper safety measures, raising ethical concerns about exploitation and environmental justice.

Question 10: Complete the truth table for an OR gate with two inputs, A and B, with the output labeled 'Result'.

Answer: A | B | Result ---|---|-------- 0 | 0 | 0 0 | 1 | 1 1 | 0 | 1 1 | 1 | 1
