   1. There are no ethical considerations
   2. Bias in algorithms, job displacement, privacy concerns
   3. Only privacy concerns are relevant
   4. Only job displacement is relevant
   Show answer

   Answer: B. Bias in algorithms, job displacement, privacy concerns

   AI raises ethical concerns about bias in algorithms, potential job displacement due to automation, and privacy implications of data collection and analysis.

5. What is the role of a cache memory in improving computer performance?

   1. It slows down the computer
   2. It is not relevant to performance
   3. It stores frequently accessed data for faster retrieval
   4. It manages network connections
   Show answer

   Answer: C. It stores frequently accessed data for faster retrieval

   Cache memory is a small, fast memory that stores frequently used data and instructions, reducing the time it takes to access them from slower main memory.
