An object model is a set of rules that an object uses in order to work and communicate with other objects, applications, or script. This group specifies standards for Web computing, such as HTML language and CSS specifications. Internet Explorer supports the DOM in its implementation, known as the Dynamic HTML Object Model . Intrinsic objects are built in and ready to use. Visual Basic, Internet Information Server, and Internet Explorer all make use of intrinsic objects.
Intrinsic objects are available to all scripts.
Client-side objects are run on the user's machine. Objects that are useful on the client can provide some type of user interface, such as a form with validation or a set of controls. Server-side objects are run on the server. Because these objects run on the server, they provide no user interface. Instead, they are useful for doing things such as working with a back-end database, providing server authentication, or managing subscriptions.
