Troubleshoot means solving computer problems using a step-by-step approach.

• A. Solving computer problems using a step-by-step approach
• B. Writing code from scratch
• C. Overclocking the processor
• D. Designing a user interface

Answer: (A)

Troubleshooting is about solving computer problems by following a careful, methodical sequence of checks and tests rather than guessing. It starts with identifying symptoms and forming a likely theory, then testing that theory step by step, implementing fixes, and verifying that the issue is resolved. This approach helps pinpoint the real cause and prevents making things worse, while also providing a clear path to confirm the solution works. The other activities—writing code from scratch, overclocking hardware, or designing a user interface—are different kinds of work (development, performance tuning, and design) and don’t focus on systematically diagnosing and resolving problems. So, solving computer problems using a step-by-step approach best captures what troubleshooting is.
