$$F(A, B) = A$$

The simplified function is $\boxed{A}$.

3) Troubleshooting is critical for maintaining the reliability and efficiency of computing systems. It involves systematically identifying, diagnosing, and resolving issues that disrupt normal operation. Effective troubleshooting minimizes downtime, prevents data loss, and ensures systems function correctly, which is vital for business continuity and user productivity.

4) The systematic process of troubleshooting involves these steps:

1. Identify the problem: Clearly define the issue, including symptoms and scope.
2. Establish a theory of probable cause: Formulate hypotheses based on observed symptoms.
3. Test the theory to determine cause: Conduct tests to confirm or deny the hypotheses.
4. Establish a plan of action to resolve the problem and implement the solution: Develop and execute a solution.
5. Verify full system functionality and, if applicable, implement preventive measures: Confirm the fix and prevent recurrence.
6. Document findings, actions, and outcomes: Record all details for future reference.

5) Documenting findings during troubleshooting is important for creating a knowledge base that helps resolve similar issues faster in the future. It also aids in identifying recurring problems or systemic weaknesses, allowing for proactive improvements. Furthermore, documentation assists in training new technicians and ensures consistent problem-solving approaches.
