2. What are  types of  system testing?
    There are essentially three main kinds of system testing :
  • Alpha testing
  • Beta testing
  • Acceptance testing
3. What is  difference between alpha, beta and acceptance testing?
  • Alpha Testing : Alpha testing refers to  system testing carried out by the test team within the development organization.
  • Beta Testing : Beta testing is the system testing performed by  selected group of friendly customers.
  • Acceptance Testing : Acceptance testing is the system testing performed by  customer to determine whether to accept or reject the delivery of the system
4. What are advantages of the black box testing?
    The advantages of this type of testing include :
  • The test is unbiased because the designer and tester are independent of each other.
  • The tester does not need knowledge of any specific programming languages.
  • The test is done from the point-of-view of  user, not the designer.
  • Test cases can be designed as soon as  specifications are complete.
 5. What are  advantages of white box testing?
    The various advantages of white box testing include :
  • Forces test developer to reason carefully about implementation
  • Approximates the partitioning done by execution equivalence
  • Reveals errors in hidden code
6. What is  test case?
A test case is a set of instructions designed to discover a particular type of error or defect in the software system by inducing a failure

7. What is  software review Explain? 
A software review can be defined as  filter for software engineering process. The purpose of any review is to discover errors in the analysis, design, and coding, testing and implementation phases of the softwaredevelopment cycle. The other purpose of a review is to see whether procedures are applied uniformly and in the manageable manner.

8. What are the types of reviews?

9. What is data flow diagrams(DFD)?
Data Flow Diagrams (DFD) are also known as data flow graphs or bubble charts. A DFD serves the purpose of clarifying system requirements and identifying major transformations. DFDs show the flow of data through a system. It is an important modeling tool that allows us to picture a system as a network of functional processes

10. What is reverse engineering?
  Reverse engineering is the process followed in order to  the find difficult, unknown, and hidden information about a software system. It is becoming important, since several software products lack the proper documentation, and are highly unstructured, or their structure has degraded through a series of maintenance efforts. Maintenance activities cannot be performed without the complete understanding of the software system.
