QUESTION - Fault Tolerance
(a) Three computers together provide a replicated service. The manufacturers claim that each computer has a mean time between failure of five days; a failure typically takes four hours to fix. What is the availability of the replicated service?
(b) In the gossip architecture, why does a replica manager need to keep both a ‘replica' timestamp and a ‘value' timestamp?
(c) Explain the difference between linearizability and sequential consistency, and why the latter is more practical to implement, in general.
(d) Explain why allowing backups to process read operations leads to sequentially consistent rather than linearizable executions in a passive replication system.
The sequence of testing is: a) Unit testing: b) Integration testing: Alpha Testing- Beta testing Acceptance Testing
The aim of regression testing is to test that the fixes have not formed any other problems elsewhere. The aim is to ensure the software has remained intact. A baseline set of data
Advantage of software package: Advantages accrue from this situation. Some of these are mentioned below: i) An efficient software package requires at least 4 to 5 man yea
Validation (Product Oriented) Validation is worried with whether the right functions of the program have been properly executed, and that this function will properly make the c
System software
Throw-away prototyping Objective: The principal objective of this model is to validate or to derive the system needs. It is developed to decrease requirement risks.
The process of evaluating a program based on implementation of that program. Dynamic analysis approaches rely on implementing a piece of software with selected test data.
Mention some of the factors to be considered during System Modeling. Simplifications Assumptions Constraints
