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.

31. Tells the computer to follow one of many possible paths of execution (one of many possible cases) depending on the value of an expression.






32. A Web scripting language that is used in both browsers and Web servers. Like all scripting languages it is used primarily to tie other components together or to accept user input.

45. Indicates that a value is a 64-bit whole number.






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