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.

23. Indicates that a variable or method belongs to a class rather than to any object created from the class.






24. This separates the content presentation (View) from the underlying business operations/content generation (Model) using infrastructure/controller Servlet (Controller) which exists between the client browser and the JSP/Servlet-generated pages. Contro






25. A distributed object model for Java program to Java program in which the methods of remote objects written in the Java programming language can be invoked from other Java virtual machines1 - possibly on different hosts.






26. Limits the computer's ability to represent extra large or extra small numbers when the computer does intermediate calculations on float and double values.






27. Introduces a path of execution to take when no case is a match in a switch statement.






28. The core framework supports clocks for synchronizing between different media (e.g. audio and video output). The standard extension framework allows users to do full audio and video streaming.

42. A lock that can be counted - i.e. how many times a resouce has been accessed and locked
