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.

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

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






5. 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.






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






7. Indicates that a method doesn't return a value.






8. Indicates that a variable or class or method can be used by any other Java code.






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. A special Java servlet-aware web server process.






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






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






13. 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.






14. Creates a new exception object and indicates that an exceptional situation (usually something unwanted) has occurred.






15. 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

21. Reuses the functionality from a previously defined interface.






22. 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.

24. An opensource Java Application Server






25. Keeps two threads from interfering with one another.






26. 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.






27. 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.






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






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






30. 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).






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






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






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






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

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






37. 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






38. CRUD: Create - Retrieve - ________ - Delete

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






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






42. Forces the abrupt end of the current loop iteration and begins another iteration.






43. A set of APIs that support the integration of audio and video clips & 2D fonts & graphics and images as well as 3D models and telephony.






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






45. Creates a subclass






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






47. 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.






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






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






50. 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.
