Which of the following does the actual .NET code execute ?

  1. MSIL

  2. CLS

  3. CLR

  4. CTS


Correct Option: C

AI Explanation

To answer this question, you need to understand the components of the .NET framework.

Option A) MSIL (Microsoft Intermediate Language) - This option is incorrect. MSIL is a low-level programming language that is generated by the .NET compiler. It is not the code that the .NET framework executes directly.

Option B) CLS (Common Language Specification) - This option is incorrect. CLS is a set of rules and guidelines that defines how .NET languages should interact with each other. It is not the code that the .NET framework executes directly.

Option C) CLR (Common Language Runtime) - This option is correct. The CLR is the execution engine of the .NET framework. It is responsible for loading and executing .NET code. When .NET code is compiled, it is transformed into a platform-neutral bytecode called MSIL. The CLR then takes this MSIL and compiles it into machine code that can be executed by the underlying hardware.

Option D) CTS (Common Type System) - This option is incorrect. The CTS is a set of rules that defines how types are declared, used, and managed in the .NET framework. It is not the code that the .NET framework executes directly.

The correct answer is C) CLR. This option is correct because the CLR is the component of the .NET framework that executes the actual code.

Correct Option: A

AI Explanation

To answer this question, you need to understand the concept of maintaining data across users in web applications.

Option A) Application object - This option is correct because the Application object in web applications allows you to store data that can be accessed and shared across all users of the application. This object is typically used to store global variables or data that needs to be shared among multiple users.

Option B) Session object - This option is incorrect because the Session object is used to maintain state and store data specific to an individual user's session. It is not meant to store data that needs to be shared across multiple users.

Option C) Response object - This option is incorrect because the Response object is used to send a response from the server to the client. It is not used for maintaining data across users.

Option D) Request object - This option is incorrect because the Request object is used to encapsulate the information sent from the client to the server. It is not used for maintaining data across users.

The correct answer is A) Application object. This option is correct because the Application object allows you to store data that can be accessed and shared across all users of the application.
