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. 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






2. Introduces a class






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






4. A library than enables CORBA objects to locate and communicate with one another.






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






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






7. 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.






8. Used to generate HTML






9. 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






10. Ends execution of a method and possibly returns a value to the calling code.






11. CRUD: Create - Retrieve - ________ - Delete






12. 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.






13. Introduces one of several possible paths of execution in a switch statement.






14. An opensource Java Application Server






15. A principal native to the operating system on which the Java platform is executing.






16. A description of the structure and properties of a class of XML files.






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






18. Introduces statements that are executed when something interrupts the flow of execution in a try clause.






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






20. 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.






21. A software "execution engine" that safely and compatibly executes the byte codes in Java class files on a microprocessor (whether in a computer or in another electronic device).






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






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






24. Basic code block of a JSP page






25. Includes a new tag library into page - allows use of tags in page






26. A special Java servlet-aware web server process.






27. Similar to the include Directive but can pass information to the included resource






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






29. Consists of class libraries - a Java virtual machine (JVM) and class loader (which comprise the runtime environment) and a compiler - debugger and other tools (which comprise the development kit).






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






31. Introduces an interface which is like a class but less specific.






32. In the Java programming language specification - describes a floating point number that holds 64 bits of data. See also single precision.






33. Causes the computer to repeat some statements over and over again (for instance as long as the computer keeps getting unacceptable results).






34. A class that wraps primitives - Integer or Boolean...






35. A set of Java APIs that may be incorporated an optional package for any Java 2 Platform Edition. The Jini APIs enable transparent networking of devices and services and eliminates the need for system or network administration intervention by a user.






36. Tests to see whether a condition is true. If it's true the computer executes certain statements; otherwise the computer executes other statements.






37. Reuses the functionality from a previously defined interface.






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






39. Allows us to invoke more than one servlet in sequence when the URL is opened with a common servlet alias.






40. 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.






41. Jumps out of a loop or switch.






42. A set of APIs that assists with the interfacing to multiple naming and directory services.






43. Indicates that a method or constructor may pass the buck when an exception is thrown.






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






45. 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.






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






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






48. Indicates that a value is a 32-bit number with one or more digits after the decimal point.






49. Refers to the superclass of the code in which the word super appears.






50. Indicates that a value is an 8-bit whole number.
