  1. 1What is .NET?


    Not an [blank_start]operating[blank_end] system
    An environment in which programs [blank_start]run[blank_end]
    Resides at a [blank_start]layer[blank_end] between operating system and other applications

    “Runtime and a library for writing and executing programs written in any [blank_start]compliant[blank_end] language”
    1. Aoperating
    2. Brun
    3. Clayer
    4. Dcompliant
  2. 2Main components in .NET

    [blank_start]Common[blank_end] Language Runtime (CLR): the execution engine that handles running applications, providing core services such as

    [blank_start]Memory[blank_end] management
    [blank_start]Security[blank_end]
    [blank_start]Exception[blank_end] handling
    [blank_start]Garbage[blank_end] collection (GC)

    [blank_start]Framework[blank_end] Class Library (FCL): a collection of reusable types that tightly integrate with the CLR

    Organized in namespace
    Language [blank_start]neutrality[blank_end]


    1. ACommon
    2. BMemory
    3. CSecurity
    4. DException
    5. EGarbage
    6. FFramework
    7. Gneutrality
  3. 3Just-in-time compilation

    Just-in-time compilation (JIT) is compilation done during [blank_start]execution[blank_end] of a program at [blank_start]run[blank_end] time rather than prior to execution.
    Java
    JVM: from [blank_start]ByteCode[blank_end] to machine code
    C#
    CLR: from [blank_start]Intermediate[blank_end] Language to machine code
    1. Aexecution
    2. Brun
    3. CByteCode
    4. DIntermediate
  4. 4Catchwords

    [blank_start].NET[blank_end]
    nN specific meaning, emphasise the "Network"-ing aspect of its technologies (perhaps)

    [blank_start]Common Language Specification (CLS)[blank_end]
    Specifies similar behaviour in .NET languages e.g. parameter passing, argument evaluation, exception handling…

    [blank_start]Common Type System(CTS)[blank_end]
    Guarantees loss-free data exchange between .NET languages, Defines rules concerning data types
    [blank_start]Common Intermediate Language (IL)[blank_end]
    Facilitate the use of code that is more platform independent

    [blank_start]Common Language Runtime (CLR)[blank_end]
    Executes CIL , JIT compiler is the integral part of CLR.

    [blank_start]Framework Class Library(FCL)[blank_end]
    A library of more than 2000 classes, interfaces, and value types that are included in the Microsoft .NET Framework SDK






    1. A.NET
    2. BCommon Language Specification (CLS)
    3. CCommon Type System(CTS)
    4. DCommon Intermediate Language (IL)
    5. ECommon Language Runtime (CLR)
    6. FFramework Class Library(FCL)
  5. 5Which of the following components of the .NET framework provide an extensible set of classes that can be used by any .NET compliant programming language?
    1. A.NET class libraries
    2. BCommon Language Runtime
    3. CCommon Language Infrastructure
    4. DCommon Type System
  6. 6Which of the following are parts of the .NET Framework?
    1. AThe Common Language Runtime (CLR)
    2. BThe Framework Class Libraries (FCL)
    3. CMicrosoft Published Web Services
    4. DApplications deployed on IIS
    5. EThe Common Language Runtime (CLR) & The Framework Class Libraries (FCL)
  7. 7What is C#?

    C# is a language designed from scratch by [blank_start]Microsoft[blank_end] to work with .NET.

    Taking advantage of what has been learned from VB, C++ and Java.
    Has the rapid GUI features of [blank_start]VB[blank_end]
    Has the added power of [blank_start]C++[blank_end]
    Has the [blank_start]object-oriented[blank_end] class libraries similar to Java

    1. AMicrosoft
    2. BVB
    3. CC++
    4. Dobject-oriented
  8. 8namespace

    C# uses the concept of namespaces to group logically related classes through the [blank_start]namespace[blank_end] keyword. These act similarly to Java packages

    You can use a namespace to organize code [blank_start]elements[blank_end] and to create globally unique types.

    They are delimited by using the [blank_start].[blank_end] Operator

    In C#, the folder structure has no bearing on the namespace.

    If a namespace is present in a library what is the correct way to use the elements of the namespace?

    Adding Reference of the namespace, importing the namespace, and using the elements of the namespace.
    1. Anamespace
    2. Belements
    3. C.
  9. 9Which of the following statements is correct about a namespace used in C#.NET?
    1. ANested namespaces are not allowed.
    2. BEvery class, struct, enum, delegate and interlace has to belong to some or the other namespace.
    3. CAll elements of the namespace have to belong to one file.
    4. DIf not mentioned, a namespace takes the name of the current project.
    5. Eusing statement can be placed anywhere in the C#.NET source code file.
    6. FA C#.NET source code file can contain any number of using statement.
  10. 10Which of the following is absolutely necessary to use a class Point present in namespace Graph stored in library?
    1. A. Use fully qualified name of the Point class.
    2. BUse using statement before using the Point class.
    3. CAdd Reference of the namespace before using the Point class.
    4. DCopy the library into the current project directory before using the Point class.
