Explain Data Annotations.

 Data Annotations

  • Data Annotations (sometimes referred to as Model Attributes), which basically allow you to add metadata to a property.
  • The cool thing about DataAnnotations is that they don't disturb the use of your Models outside of the MVC framework.
  • When generating the label, the name of the property is used, but property names are generally not nice to look at for humans. As an example of that, we might want to change the display version of the FirstName property to "First Name".

public class WebUser

{

[Display (Name="First Name")] public string FirstName { get; set; }

}

Taxonomy of virtualization Virtualization is mainly used to emulate the execution environment, storage, and networks. The execution environment is classified into two: – Process-level – implemented on top of an existing operating system.  – System-level – implemented directly on hardware and does not or minimum requirement of the existing operating system. OR,  Virtualization covers a wide range of emulation techniques that are applied to different areas of computing. A classification of these techniques helps us better understand their characteristics and use  V irtualization is mainly used to emulate  ● Execution Environments: To provide support for the execution of the programs eg. OS, and Application.  ○ Process Level: Implemented on top of an existing OS that has full control of the hardware  ○ System Level: Implemented directly on Hardware and do not require support from existing OS.  ● Storage: Storage vi...

Pure Versus Partial EC EC takes several forms depending on the degree of digitization (the transformation from physical to digital). Companies utilizing pure EC conduct all of their business online.
