PostBack is the name given to the process of submitting an ASP.NET page to the server for processing.
In the context of web development, a postback is an HTTP POST to the same page that the form is on. In other words, the contents of the form are
Posted back to the same URL as the form
So if a page does post back that means it sends page data( page data includes page controls,control values ,viewstates etc) to the server where it does some processing ( Processing could be any events fired or redirecting to some other page etc) and returns
back with processed data(HTML) with a refreshed page which you see on your browser.
It's the whole mechanism, in combination with the page life cycle, which makes up an important part of ASP.NET webforms.
Basically it's the process of posting the rendered form from the browser to the server, handling the information and events there in a predetermined order (the page life cycle) and resending that handled page back to the page after rendering.

Hi,
It's the whole mechanism, in combination with the page life cycle, which makes up an important part of ASP.NET webforms.
Basically it's the process of posting the rendered form from the browser to the server, handling the information and events there in a predetermined order (the page life cycle) and resending that handled page back to the page after rendering.
To learn more about the process I suggest you take the time to read this article: http://msdn.microsoft.com/en-us/library/ms972976.aspx.
