    MEF Meaning:

    MEF or the Managed Extensibility Framework refers to a digital library for the formation of extensible technical applications. Using it, software developers and programmers can utilize the available extensions without any coding or configuration. You can even use MEF across applications during their development stage. You can reuse it for multiple times.

    Benefits of MEF:

    • MEF helps in arranging smaller components 
    • An MEF component can be easily categorized as imports (dependencies) or exports (capabilities).
    • MEF helps an app function without any codes or config files.
    • You can analyze all parts using metadata.

    Location of MEF

    MEF is a constituent part of the .NET framework. Everytime you use .NET, you have to use MEF as well. MEF works in sync with .NET client as well as ASP.NET and in other technology as well. 

    MEF Composition

    MEF composition basically includes a composition container having all available parts assembled together. It is responsible for performing various computing operations. A part represents any object through which any value can be exported or imported.   

    Imports and Exports of MEF:

    Imports and exports are just a behavioral pattern of how MEF parts operate within the .NET framework. When the component delineates the necessity of assigning a value to a particular object, it is called Imports. While export determines whether the same is available or not. Each import has to be matched with their corresponding export in the MEF.

    Method Overloading Meaning:

    Method Overloading, a benefit permitting a class to have more than one method having the same name with different parameters, is similar to Constructor Overloading in Java if their argument lists are different.

    It allows a class to have more than one constructor having different argument lists which means the parameters that a method has.

    Thus it denotes if a class has many or several methods having the same name but different in parameters, it is Method Overloading.

    Functions of Method Overloading:

    It has several functions primary among them being:

    Being similar to Constructor Overloading in Java, it allows a class to have more than one constructor having different argument lists (also known as parameter lists).

    Its functionality can be utilized by declaring the same method with varied parameters which must be different in number, sequence or types of parameters (or arguments).  

    One of the functions of it relates to Static Binding which happens at compile time. Under Method overloading, binding of method calls to its definition happens at Compile time.

    Types of Method Overloading:

    Following are the main types of Method Overloading:

    • Function overloading.
    • Operator overloading.

    Note:

    In the light of the above types, it is necessary to mention that there are two possible ways to overload which are:

    • Changing Number of arguments.
    • Changing the data types.

    Features of Method Overloading:

    Following are the main features of Method Overloading:

    It is a static polymorphism system (methods are binded during the compilation process).

    Overloading relates to runtime (binding) and the binding of methods is done at compile-time. As a result, multiple processes are not required during run time.

    The numbers of arguments are part of the actual method overloading.

    Benefits of Method Overloading:

    This has several benefits primary among them being:

    • It is time-saving as it reduces execution time because the binding is done during compilation time.
    • An overloading mechanism achieves flexibility.
    • Code reusability is achieved; hence it saves memory.
    • Code complexity is reduced. Hence provides consistency of code. 

    Conclusion:

    Method Overloading has revolutionized the working methods as it eliminates multiple methods with the same name. This has tremendous overloading functionality benefits in code readability and reusability of the program.

    MIME Definition:

    MIME is the acronym or short form of Multipurpose Internet Mail Extensions. It is basically a content type on the internet in which the data contained in an internet message can be clearly classified as it would in an email or in an HTTP message. 

    We can also say, to simplify the meaning, MIME is an Internet Standard. It extends the format of email message messages to support text in character sets other than the American Standard Code for Information Interchange or ASCII. MIME also facilitates attachments of audio, video, images, and application programs. 

    How Does It Work?

    It should be mentioned here that the MIME is an extension of the original Simple Mail Transport Protocol or SMTP in technical terminology that facilitates or allows the users to exchange various types of data files. Such files may be audio, video, visuals, and application programs.

    The messages or matters with MIME formatting can be sent with a number of systems including SMTP, POP (Post Office Protocol), and IMAP (Internet Message Access Protocol). MIME is a useful system with high technological sophistication.

    Being a versatile system or method, MIME permits your mail Web browser to send and receive written text, audio, video, and graphics files via Internet mail. Attachments under the MIME are faster and versatile.

    How can you attach heavy files using MIME?

    The large files or heavy email attachments, under MIME, can be compressed for better transmission with WinZip or StuffIt. The photographs can be sent in the JPEG format which requires less space and uploading is also faster.

    MIME protocol has several useful features which, among others, include multiple attachments in a single email, supports multiple languages (i.e. Indian languages, German, English, French, and Spanish, etc..), supports multiple attachments in a single email, and the non-ASCII characters.

    In Conclusion:

    One of the biggest benefits of MIME is that it provides the facility of connecting HTML and CSS to email, due to which people can design email as per their requirement and make it attractive and beautiful.

    MSIL Definition:

    Microsoft Intermediate Language (MSIL), also known as Common Intermediate Language (CIL), is basically a rule-book or guide or a set of instructions that are platform independent. The MSIL or CIL are created by the language-specific compiler from the source code. 

    Basically, it is a platform which is independent. As a result (being independent), the MSIL or CIL can be executed or put into active mode on any of the Common Language Infrastructure supported environments such as Windows. 

    It is converted/changed into a particular computer environment specific machine code by the JIT (Just in Time) Compiler which must be done before the MSIL can be executed or put into active mode. 

    The MSIL can be converted into the machine code on a specific requirement basis. To exemplify this point, the JIT (Just in Time) compiler compiles the MSIL as required rather than the whole of it. 

    When we talk of or explain the CLR, it must be mentioned that the execution process includes the creation of the MSIL and the conversion of the MSIL into machine code by the JIT compiler. 

    Features of MSIL:

    • It has several features. The important features are: 
    • There are opcodes that are one or two bytes long
    • The CLR, along with the MSIL, metadata containing     information like definition and signature of the types in the code, runtime information, is also produced in the compilation.
    • CLI assembly is created by assembling the MSIL.
    • MSIL includes instructions for loading, storing, initializing, and calling methods on objects.
    • MSIL issues instructions for arithmetic and logical operations, control flow, direct memory access, exception handling, and other operations. 

    Conclusion:

    The MSIL and CIL have revolutionized Internet functioning. It has made many difficult computer tasks and is growingly becoming popular across the world. It is particularly useful as the system happens to be machine agnostic and can be turned into native code quickly.

    As a result, it simplifies computer operations.

    MVC Definition:

    MVC is the acronym for Model–View–Controller. It is basically a software design pattern which is mostly applied and used to develop the user interfaces dividing the related program logic into interconnected elements.

    MVC is applied to separate internal representations of information from the ways information is presented to and accepted from the user.

    This software design pattern is traditionally used for desktop Graphical User Interface or the GUIs. The GUIs turned useful and therefore, popular for designing different web application purposes. This is the primary reason why the MVC became popular programming languages.

    History of MVC

    MVC is now about 50 years old.

    In the 1970s, Trygve Reenskaug introduced MVC into Smalltalk-79 while visiting the Xerox Palo Alto Research Center.

    In the 1980s, the modern format of MVC was put into implementation by Jim Althoff and others who used it for the Smalltalk-80 class library.

    1996, the use of the MVC pattern in web applications grew after the introduction of NeXT’s WebObjects. The use of MVC gained momentum after 2002 when Spring was introduced. It had a strong bond between Java and MVC.

    In July and December respectively in 2005, the frameworks  Django (July 2005, for Python) was introduced followed by Rails (December 2005, for Ruby).

    With this, the popularity of MVC’s increased globally.

    Utility of MVCs

    MVCs have major utilities.

    MVCs act as the application’s dynamic data structure. This is independent of the user interface.  One of the many utilities of MVC is that it directly manages the data, logic, and rules of the application. 

    It enables multiple viewing of any representation of information such as a bar chart, diagram, map, data-table, or other numerical tables. It also acts as an effective controller accepting input and converting the command to the model or view.

    Conclusion:

    MVCs now have emerged as an ultra-sophisticated management tool to implement various commands in a controlled regime. It receives user input from the controller and the view renders the presentation of the model in a particular format.

    MVC also acts as the “core of the solution” to a problem while allowing it to be adapted for each system.

    Namespace Definition:

    A namespace refers to a specialised section, which is used to define the scope of identifiers used in a programming language like C++. Identifiers can be anything: functions, variables, and etc. Namespaces help in organising codes into their respective logical groups and preventing name collisions within C++. 

    All identifiers are arranged in such a way that each of them can see one another without any specific qualification. 

    When you are using only one to two identifiers, you should use the declaration to let identifiers come within its scope while keeping other identifiers outside the namespace. A using directive should be positioned at the header of a .CPP file. You must not use directive in header files in usual cases because it will then include all elements in the namespace—it may lead to name collision, which is extremely tough to debug. 

    Define Namespace Member:

    Namespace members can be defined using a lot of blocks in either a single file or multiple folders. A compiler helps in joining parts of namespaces through processing, with all members constituting the namespace. 

    The global namespace 

    When an identifier is not clearly mentioned in an explicit namespace, it automatically becomes part of the implicit global namespace. Programmers are advised not to make declarations at the global namespace as far as possible. 

    The Standard Namespace

    The standard namespace or std namespace refers to standard library types and functions in C++. 

    Namespace Aliases

    Namespace Aliases can be used to denote a name using codes only. When names become too difficult to read or are too long, programmers use namespace aliases to simplify the task.

    What are OOPS Concepts?

    OOP (Object Oriented Programming) concepts are extremely essential for maintaining a host of software programs and developing them from scratch. 

    Object Oriented Programming or OOP mainly focuses on ‘Objects.’ All OOP languages are based on class systems while defining data attributes and functions. It is helpful in creating class-based objects in software programs. 

    Some of the famous OOP languages are: C++, Python, and Java among others. Using the same class you can display multiple objects on it. 

    For example; When you take a class representing the occupation. A person would also have other traits like tall, handsome, good-natured and at the same time it may also include a function like ‘mentionMyName’ and on entering the command the person’s name will appear on the screen. 

    Using OOPS, you can set different data attributes for each person. That is why developers often resort to OOP techniques while creating complex software programs. 

    What Is its Significance? 

    OOP concepts are significant in JAVA because, through it, software programmers and developers can create reusable technical components while keeping the highest level of security intact. OOP aims at saving time and making each step of programming work easily without any fuss. 

    What are the four basic objects of OOPS? 

    Encapsulation:

    It helps in creating a protective layer that helps in keeping the data and class in a single folder using codes. It binds the data and works as a single unit. 

    Abstraction:

    It helps in designing a software program and separating the interface from the main class. In other words, using abstraction, we can abstract important information while keeping the rest as it is stored in the folder.

    For example: When we press a mobile factory setting key, it works but we don’t see much on-screen on how the process runs inside the device. 

    Inheritance:

    In technical terms, all classes can be named into hierarchies depicting certain properties. When one class contains the properties of another class, it is called parent class and we can say that the latter inherited certain properties from the former. It follows a typical “IS–A” type of classification.

    Polymorphism:

    It helps in the uniform treatment of all classes belonging to the same hierarchy. With a little tweak of codes, one can easily edit objects from their hierarchy roots.

    For example: If a class called “Mammal” has three classes: Tiger, Monkey, and Goat. 

    If “MakeNoise” command makes them bark, we can instead separate their bark and sound based on what they are actually called. 

    The Advantages of OOPS (Object Oriented Programming System) 

    • It offers clear instruction for programs.
    • All objects can be reusable in other projects as well, thus saving costs.
    • Quite effective in creating large software programs. 

    The Conclusion:

    Thus OOPS refer to a software programming language through which developers can build various software programs and other useful apps for the general public at large. It offers a cheaper and quicker way of developing complicated apps from scratch.

    Protected Configuration: Meaning and Explanation 

    Protected configuration refers to a technical process through which any data is protected using enhanced layers of security applications. It makes it difficult for any third-party or intruders to get inside your sensitive data and steal the same. 

    Using the protected configuration path, you can make it even more difficult for hackers and intruders to go inside your site and get access to your configuration file.

    By sensitive information, we mean user id, email id, connection strings, and encryption codes. Mostly, all sensitive information is stored inside ASP.NET, and using a protected configuration route you can easily encrypt essential details. 

    What is its function? 

    Using protected configuration you may not be able to encrypt or decipher configprotecteddata folder of your config file. That is why Protected configuration primarily helps in hiding sensitive details from outsiders. 

    Managing Protected Configuration 

    A website admin should use the ASP.NET IIS registration key (ASPNET_REGIIS.EXE)—executable file to manage the protected configuration of essential files. In order to implement a protected configuration provider, start a class to inherit the Protected Configuration Provider abstract class. 

    Types of Protected Configuration offered by .NET: 

    •   System.Configuration.DPAPIProtectedConfigurationProvider 
    •   System.Configuration.RsaProtectedConfigurationProvider 

    In Conclusion:

    With ASP.NET 1.0, the admin can easily store multiple sensitive data and information in a highly secret manner. Developers know the importance of connection strings as they contain necessary website admin credentials and other sensitive data.

    It is recommended to use a protected configuration route to save essential data in an encrypted format, which nobody can steal or hack into your server. It is compatible with both ASP.NET and NON-ASP.NET frameworks.

    Response.Redirect Definition:

    Response.Redirect refers to an HTTP code, which sends the user to a new page updating the address bar and adding the same into the browser track history. You can press the backspace on your browser to go back. 

    What is the difference between Response.Redirect and Server.Transfer? 

    Server.Transfer is a specialised command, which doesn’t get changed at the address bar. You can’t press the backspace because it doesn’t go back. Response.Redirect asks the online browser to go to another page, on the other hand, Server.Transfer reduces server requests while keeping the URL the same. 

    Response.Redirect: Explanation 

    • The address page is redirected forever.
    • It helps in navigating from one app to another.
    • You can bookmark the page by clicking on the bookmark option on the address bar. 

    Server.Transfer: Explanation

    • The webpage is not redirected permanently.
    • You can only use the app for navigating within itself.
    • The URL keeps on changing.
    • Bookmarking option on the address bar is not available.

    The Suitability of Response.redirect 

    • When you want to redirect the request to an HTML page on our web server. 
    • When you need not preserve Query String and Form Variables from the original request. 
    • When users want to see the new redirected URL and bookmark the same if needed. 
    • When you want to move the current web page data to another .aspx page. 
    • When you wish to display the URL on the browser.

    RIA Definition:

    The short form of Rich Internet Application is known as RIA. It is in-built within the framework of a Web browser. The RIA eliminates software installation on the client-side to work.

    Thus, the RIA was created to deliver the same features and functions normally associated with Desktop applications but much faster, versatile and safe.

    Most of the RIAs run their client portions within a special isolated area of the client desktop which is called a Sandbox. The sandbox protects the client’s file and operating system.

    Thus it also provides safety to the application server of the client. It may be mentioned here that there are some RIAs that work properly with one or more specific browsers thus it is not for general purposes.

    Features/characteristics of RIA:

    The RIA has several features. The main features are:

    • Web-based applications similar to features/characteristics of graphical desktop applications.

    • RIAs are faster and more engaging.

    • RIAs offer better visual experience.

    • RIAs are more interactive than traditional browser applications that use only HTML and HTTP.

    • It splits the processing across the Internet/network divide by locating the user interface.

    • The RIA is the client engine that intermediates between the user and the application server.

    Main Features of RIA:

    The RIAs has several features including:

    RIAs Interacts Directly:

    RIAs allow a wider range of controls facilitating greater efficiency. To exemplify this point, users can interact directly with page elements including a map, chart, graph, and images through editing or drag-and-drop tools.

    It Keeps on Updating the Page Partially:

    This is one of the most useful features of the RIA.  It incorporates such benefits like real-time streaming, high-performance client-side virtual machines, and local caching mechanisms. Subsequently, the wait times are reduced, increasing the responsiveness.

    Better feedback system:

    Because of their ability to change parts of pages without reloading, RIAs can provide the user with fast and accurate feedback, real-time confirmation of actions and choices, and informative and detailed error messages.

    Benefit of Offline use:

    It can work offline when connectivity is unavailable.

    What are the advantages and disadvantages of RIAs?

    RIAs perform better than traditional apps. This is a major advantage. However, there are certain disadvantages of RIAs also. Following are major advantages and disadvantages of this system:

    The Advantages of RIA:

    1. Mobile Access to Information

    2. Tracking of Batch and Item Level Made Easier

    3. Master Item Synchronization

    4. Better Data Visualization

    The Disadvantages of RIA:

    It has some disadvantages which are following:

    1. RIAs sometimes run very fast while displaying content.
    2. Often, the customer might not be able to notice what he or she actually wants them to see due to the system’s very fast working.
    3. New functionalities require new information.
    4. New functionalities require new information putting the user in trouble, at times. 

    Briefly history of RIA:

    RIA, a term coined in 2002, took several years to progress, mature and finally shape. The first RIA research appeared in 2004 and from 2007, there had been major research on it which further increased after 2009.  

    For all practical purposes, the RIA was introduced in 2002 by Macromedia (which later became Adobe Flash).  This term was given in a white paper of March 2002 by Macromedia. 

    In Conclusion:

    The RIAs allow the client system to handle local activities, calculations, and reformatting jobs thus reducing the amount and frequency of client-server traffic.
