What does the View State represent in a Visualforce page?

Hi Anjali,

View state is a state of you VF page, which help salesforce to regenerate VF page when it come back from server.

For example, when you create a VF page having a some input fields,  consider that you load this page with some value and there are some required field on this page and when you click on a button this page will get submitted to server then when server replay back your page should be loaded in same state as it was before submit button click, to maintain this salesforce exchange data between VF and servers and this information which salesforce maintain is know as View state.
