Part 4

Question 1

Development technique are used that either minimize the possibility of mistakes or trap mistakes before they result in the introduction of system faults

Answer 1

Fault Avoidance

Question 2

Verification and validation techniques that increases the probability of detecting and correcting errors before the system goes into service are used

Answer 2

Fault Detection and Removal

Question 3

Run-time techniques are used to ensure that system faults do not result in system errors and/or that system errors do not lead to system failures

Answer 3

Fault Tolerance
