Software Reliability Basics
Multiple choice questions test basic concepts (MTBF), which is rarely tested
Non-key
Basic concepts of software reliability
In this chapter, the first focus
MTTF: mean time between failures
MTTR: mean time to repair
MTBF: mean time required for failure or maintenance
Series and parallel system reliability calculation
Computing system reliability
Parallel systems are: 1 - unreliability
Software reliability testing
Software Reliability Modeling
Software Reliability Management
Software Reliability Design
The second focus of this chapter (fault tolerance, error detection technology)
Fault tolerance, error detection technology
Error avoidance: avoid before the system is running.
Fault tolerance: while the system is running.
Fault-tolerant technology mainly uses redundancy methods (redundancy is the basis of fault-tolerant technology)
Structural redundancy
Information redundancy
Time redundancy
Additional redundancy
