A fault in a computer program which prevents it from working correctly is known as                        ?

The correct answer is Bug because this software engineering term explicitly identifies an error, flaw, or fault in source code that leads to unintended behavior.

• Bug: This is the correct choice. Programming bugs arise from syntax mistakes, logical oversights, or structural loop anomalies. Resolving these issues involves running test cases and debugging the codebase.


• Incorrect Options:
  
  
  
  • Boot: This is incorrect. Booting is the initialization phase a computer goes through to load its operating system into memory.
  
  
  • Strap / Biff: These are incorrect. These are non-applicable distractors with no standing in runtime diagnostics terminology.
