Information in a memory that is no longer valid or wanted is known as

  • A.non-volatile
  • B.volatile
  • C.surplus
  • D.garbage

Answer: D

Correct answer: garbage

Data left in memory that is no longer valid or wanted is garbage, and reclaiming the space it occupies is garbage collection. Volatile and non-volatile describe whether memory survives a loss of power, which is a property of the hardware rather than of the data.
