Explain two safety precautions for computer setup and one benefit of reusing computer e-waste.

Here are the solutions to questions 7b, 7c, and all parts of question 8. 7. b) Explain two safety precautions to observe when setting up a computer.* i. Ensure proper grounding*: Always connect the computer and peripherals to properly grounded power outlets to prevent electrical shocks and protect equipment from power surges. ii. Manage cables neatly*: Arrange cables in an organized manner to prevent tripping hazards and ensure proper airflow around components, which helps prevent overheating. c) State one benefit of reusing functional computer e-waste.* Reusing functional computer e-waste helps reduce environmental pollution* by diverting electronic devices from landfills and conserving natural resources that would otherwise be used to manufacture new products. 8. a) Explain three advantages of using networked storage in the lab.* i. Centralized Data Management*: All data is stored in one central location, making it easier for administrators to manage, back up, and secure information efficiently. ii. Enhanced Collaboration*: Students and teachers can easily access and share files from any computer in the lab, facilitating teamwork and collaborative learning. iii. Cost-Effectiveness*: Instead of purchasing individual storage devices for each computer, a single networked storage solution can serve all machines, reducing overall hardware costs. b) The lab uses a touch screen and a projector for presentations.* i) Explain how data is input and output in this setup.* Input: Data is input through the touch screen* when a user interacts directly with the display using their finger or a stylus to select options, type, or draw. Output: Data is output through the projector*, which displays visual information from the computer onto a larger surface, making it visible to an audience. ii) Suggest one method to secure data on the lab computers.* Implement strong password policies*: Require all users to create complex passwords and change them regularly to prevent unauthorized access to individual user accounts and stored data.
