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. (&& or || or & or |)






2. A standardized (ECMA) language for creating Windows .NET applications and services and libraries - with a syntax similar to Java and C++.






3. 8 bit - unsigned byte (0 - 255)






4. System.Double






5. Integrated Development Environment






6. System.Int16






7. Allows a class to define multiple implementations of a method based on the number and types of arguments passed (Overloading).






8. Four things common to all software development: _______ - Flow of Control - Identifiers & Arguments - Testing / Debugging






9. System.UInt32






10. 64 bit integer data






11. A method that is called whenever an Object is created. The method uses the same name as the Class.






12. System.Byte






13. System.UInt64






14. Field whose value can never change. Declared with 'const' keyword






15. Container for one or more Visual Studio Projects.






16. true or false






17. The act of generalizing or thinking about an object in general terms. The act of identifying the data members and behavior of a Class.






18. (< or > or <= or >=)






19. 32 bit - unsigned integer data






20. Names reserved by the compiler that coders are not allowed to use as identifiers.






21. System.Char






22. The output produced by the C# Compiler - typically a .dll or .exe. Produced by a Project in Visual Studio






23. Represents date and time data with a 100 ns resolution






24. A symbol that specifies an operation to be performed on one or more variables.






25. Only requires one operand usually a count+1 or a count++ or a count--






26. A Class that inherits characteristics from another Class.






27. Object Oriented Programming relies on dot.notation. Dot Notation enables public methods to be fully accessible from outside an object. Member names are separated by a dot (.). Syntax is method-defined-in-class.bject-in-runtime-of-class






28. Sits behind GUI (Graphical User Interface) and provides event listeners






29. Runs in a command prompt window rather than a GUI (graphical User Interface) one.






30. Groups classes together so that they have a unique identifier






31. 64 bit integer data






32. The result of successful compilation of source code written in any .NET targeted language - e.g. C# or Visual Basic or C++.






33. Something an object can do. A named sequence of events. Should always have a meaningful name eg calculateIncomeTax.






34. Box which can be typed into at runtime. Can display large amounts of scrollable text for the user. To create a scrollable one in Visual Studio set the multiline property to 'TRUE' and the Scrollbars property to 'VERTICAL'.






35. System.Single






36. Names used to identify program elements (e.g. namespaces & classes & methods & variables). Must always start with a letter. Always case sensitive. When multiword must be presented in CamelCase. keywords are an example of an identifier.






37. Symbols which transform and combine expressions






38. When a sub class passes down all the behaviours of the original parent class






39. 128 bit fixed precision (financial)






40. A Member that cannot be accessed/invoked through an Object Instance.






41. The process of hiding and restricting access to the implementation details of a data structure.






42. Something that has a different number of parameters to it's predecessor






43. Text as Unicode characters






44. Most common kind of reference type. They define objects. They must have at least one method and one field.






45. Access is limited to the current Assembly






46. Contains the class definitions that allow access to the functionality provided by .NET.






47. Just-in-time compilation






48. Block of memory where objects live. Whenever a new object is created it is allowed onto the heap. Old objects are regularly deallocate from the heap to save available memory






49. Un-orderd sequence of elements of the same type. Stores a fixed number of static elements of a particular type.






50. The concept of defining subclasses of data objects that share some or all of the parent's class characteristics - enabling the reuse of code.
