Store global information about the application

No, You have to use Server. Transfer to pass the data to another page.

By default all pages in .NET post back to themselves. The view state keeps the users input updated on the page.

Server controls are built-in. User controls are created by the developer to allow for the reuse of controls that need specific functionality.

ASP. NET provides In-Process and Out-of-Process state management. In-Process stores the session in memory on the web server. This requires the a “sticky-server” (or no load-balancing) so that the user is always reconnected to the same web server. Out-of-Process Session state management stores data in an external data source. The external data source may be either a SQL Server or a State Server service. Out-of-Process state management requires that all objects stored in session are serializable.

It allows the page to save the users input on a form across post backs. It saves the server-side values for a given control into View State, which is stored as a hidden value on the page before sending the page to the clients browser. When the page is posted back to the server the server control is recreated with the state stored in view state.
