2. What does BIOS stand for?

   1. Basic Input Output System
   2. Binary Input Output System
   3. Basic Input Output Software
   4. Binary Input Output Software
   Show answer

   Answer: A. Basic Input Output System

   BIOS stands for Basic Input Output System. It's a firmware program that initializes hardware components during startup.

3. Explain the concept of Von Neumann architecture.

   1. Separate memory for instructions and data
   2. Shared memory for instructions and data
   3. No memory for instructions
   4. No memory for data
   Show answer

   Answer: B. Shared memory for instructions and data

   The Von Neumann architecture uses a single address space for both instructions and data, allowing them to be stored and accessed in the same memory.

4. Analyze the ethical considerations surrounding the use of artificial intelligence in computer systems.

   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.
