A Failure is an event where a system does not meet its requirements. It occurs when the system operates outside specified limits.
Types of Failures:
1. Hardware failures
2. Software failures
3. Network failures
4. Data failures
5. User interface failures
Characteristics of Failures:
1. Deviation from expected behaviour
2. May cause system malfunction
3. Can lead to data loss or corruption
4. Often requires intervention to resolve
5. May impact system availability or performance
Failure Analysis Helps:
1. Identify root causes
2. Improve system reliability
3. Guide maintenance efforts
4. Enhance system design
5. Develop better testing strategies
