"Session" is data stored per user session. "Viewstate" is an ASP.NET thing. It's a way for the application to maintain state about a particular form and its child controls. Your ASP.NET application might consist of several pages/forms. There might be a piece of data that you want to access across all pages. You could place that in a Session variable. However, you rarely need to worry about ViewState, ASP.NET manages that itself.

I've written some articles that discuss Viewstate: http://www.tgreer.com/aspnet_html_02.html

This article shows how you might use Session: http://www.tgreer.com/aspnet_html_04.html
