System Analysis And Design

Subject : it-skills
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

15. Flow Chart: Decision/Conditional - a question or branch in the process






16. Type of system implementation that is used in its entirety only in one locality or area






17. Flow Chart: Connector - continues a chart to another point on the same page






18. System testing is performed by ____________






19. ____________ Testing: the testing of a collection of units that have a logical relationship or flow from the user's perspective.






20. ____________ Testing: Another name for integration testing

22. Program testing is carried out by computer _________






23. Flow chart: ____________ represents an event which occurs automatically. Such an event will trigger a subsequent action - for example 'receive telephone call' - or describe a new state of affairs






24. _________ accounts for the greatest expenditure involved in the cost of creating and maintaining a system.






25. Flow Chart: comment

29. Contains all the information needed for processing and distributing online and printed output






30. ____________ Testing - (sometimes called Integration and Testing - abbreviated "I&T") is the phase in software testing in which individual software modules are combined and tested as a group. It occurs after unit testing and before system testing.
