Reliability of software is directly dependent on

  • A.quality of the design
  • B.number of errors present
  • C.software engineers experience
  • D.user requirement

Answer: B

The reliability of software depends directly on the number of errors present.

Reliability is the probability that the software will run without failure for a stated time, and failures are caused by errors in it. The fewer the errors, the more reliable it is. The quality of the design (A) affects reliability only through the errors it leaves, the engineers' experience (C) is an indirect factor, and the user requirement (D) is what the software is built to meet, not what decides how often it fails.
