A. ISO 9000
B. McCall model
C. Boehm model
D. ISO 9126
Explanation: ISO 9000 is software certification.
A. MTTR
B. MTTF
C. MTSF
D. MTBF
Explanation: FIT reports the number of expected failures per one billion hours of operation for a device. This term is used particularly by the semiconductor industry but is also used by component manufacturers.
A. forward error recovery mechanism
B. backward error recovery mechanism
C. All of the mentioned
D. None of the mentioned
Explanation: Exception handling is a forward error recovery mechanism, as there is no roll back to a previous state; instead control is passed to the handler so that recovery procedures can be initiated.
A. Error seeding
B. NHPP
C. Input domain
D. Halstead’s software metric
Explanation: Halstead’s software metric is a deterministic model.
