Software safety is quality assurance activity that focuses on hazards that
may cause an entire system to fail.
Software safety is a software quality assurance (SQA) activity. Pressman describes it as the identification and assessment of potential hazards that may affect software negatively and cause an entire system to fail. It matters most for embedded and safety-critical systems such as avionics, medical devices and process control, where a software fault can lead to loss of life or property.
The activity works in two stages: early in the process, hazards are identified and analysed using techniques such as fault-tree analysis; then safety-related requirements are specified so that the design either removes the hazard or keeps its consequences within acceptable limits.
Why the other choices do not describe it: hazards that merely affect the reliability of one software component are the subject of software reliability analysis, which measures failure probability rather than system-level danger; user input errors are one possible cause of a fault, not the defining focus of safety analysis; and hindering profitable marketing is a business risk handled in risk management, not a safety hazard.
may cause an entire system to fail option is correct.
Maximum possible value of reliability is

Which one of the following is not a definition of error ?
Assume that a program will experience 200 failures in infinite time. It has now experienced 100 failures. The initial failure intensity was 20 failures/CPU hr. Then the current failure intensity will be
