What does FRU stand for?

  1. Field Replaceable Unit

  2. Fast Response Unit

  3. Fixed Resolution Utility

  4. File Retrieval Unit

The correct answer is: Field Replaceable Unit

FRU stands for "Field Replaceable Unit". This refers to a component or part of a larger system that is designed to be easily removed and replaced when needed. This allows for quick and efficient maintenance of the system as a whole. Option B, "Fast Response Unit", is not the correct answer because this term is not commonly used in the context of technology or system components. Option C, "Fixed Resolution Utility", is also not correct. This phrase does not make sense in the context of system maintenance or replacement. Option D, "File Retrieval Unit", is not correct because FRU reflects a physical component, while file retrieval is a function of a software or system tool. In addition, FRU is not commonly used in this context. Therefore, option A is the best answer.
