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.
1. Indicates that a variable or method can be used in subclasses from another package.






2. An opensource Java Application Server






3. A tree of objects with interfaces for traversing the tree and writing an XML version of it as defined by the W3C specification.






4. You can't use this word in a Java program. The word has no meaning. Because it's a keyword - you can't create a const variable.






5. A software development environment for writing applets and applications in the Java programming language. Technically - the JDK is the correct name for all versions of the Java platform from 1.0 to 1.1.x.






6. Indicates that a value is a character (a single letter or digit or punctuation symbol and so on) stored in 16 bits of memory.






7. 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.






8. A platform-independent file format that aggregates many files into one. Multiple applets written in the Java programming language and their requisite components (.class files & images & sounds and other resource files) can be bundled in a JAR file an






9. Keeps two threads from interfering with one another.






10. Tests the truth of a condition that the programmer believes is true.






11. Creates a subclass






12. Indicates that a value is a 16-bit whole number.






13. Common Object Request Broker Architecture. A language independent distributed object model specified by the Object Management Group (OMG).






14. A software development environment for writing applets and application in Java .






15. Repeats some statements over and over again (as long as a condition is still true).






16. Imposes strict rules on the use of a variable by more than one thread at a time.






17. Indicates that a value is a 64-bit number with one or more digits after the decimal point.






18. Indicates that a variable or method can be used only within a certain class.






19. Introduces statements that are watched (during runtime) for things that can go wrong.






20. Creates a newly defined type






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






22. A CORBA standard for building server-side applications that are portable across heterogeneous ORBs.






23. A portable platform-independent reusable component model. A component that conforms to this model is called a bean.






24. An industry standard for database-independent connectivity between the Java platform and a wide range of databases. The JDBC provides a call-level API for SQL-based database access.






25. A protocol used for communication between CORBA object request brokers.






26. A tool for tracking and managing source file changes - written in Java.






27. Used to generate HTML






28. Reuses the functionality from a previously defined interface.






29. A set of Java APIs that provide CORBA (Common Object Request Broker Architecture) interoperability and connectivity capabilities for the J2EE platform. These capabilities enable J2EE applications to invoke operations on remote network services using






30. Puts the code into a package






31. A Java class that can be loaded into and run dynamically in a Servlet container on a web server; interact with web clients via a request-response model based on HTTP.






32. Tests to see whether a certain object comes from a certain class.






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






34. You can't use this word in a Java program. The word has no meaning. Because it's a keyword you can't create a goto variable.






35. A tool for checking compliance of applications and applets to a specification.






36. Type of Java program (as opposed to a stand-alone program) which is embedded in a web page (requested from a server) and run on a client-side browser






37. A definition of the interfaces that permit CORBA objects to participate in transactions.






38. Enables the programmer to use code that was written in another language (one of those awful languages other than Java).






39. A self-reference






40. Indicates that if and when an object is serialized a variable's value doesn't need to be stored.






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






42. Sets attributes and properties specific to the current JSP page






43. Used to terminate the execution of the current JSP page and switch control to another resource






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






45. An extension that adds graphical user interface class libraries to the Abstract Windowing Toolkit (AWT).






46. 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.






47. _______ separates Java code/functionality from page design and use of tags in JSP and allows for re-use of beans






48. Introduces the last will and testament of the statements in a try clause.






49. A subset of the Java Development Kit (JDK) for end-users and developers who want to redistribute the runtime environment alone. The Java runtime environment consists of the Java virtual machine1 - the Java core classes and supporting files.






50. Evaluates interior code to a String and feeds it to the implicit "out" print writer (JspWriter) - done at time of JSP page request
