storage retain information without continuous electrical power.
3. What is the primary purpose of an operating system?
A. To manufacture computer hardware
B. To manage computer hardware and software resources
C. To create electrical power
D. To replace application software
Answer: B. To manage computer hardware and software resources
Rationale: An operating system manages resources such as memory,
processors, storage, input/output devices, files, and running
applications. It also provides an interface through which users and

7. What is the main purpose of a firewall?
A. Increase monitor resolution
B. Filter and control network traffic
C. Store backup files
D. Compress documents
Answer: B. Filter and control network traffic
Rationale: A firewall examines network traffic according to defined
security rules and can allow or block connections. Its purpose is to
reduce unauthorized network access and associated risks.
8. Which security principle ensures that authorized users can access
information when needed?
A. Confidentiality
B. Integrity
