What does each instance of spsite and spweb contain?
Each instance of SPSite and SPWeb contains a reference to an SPRequest object that, in turn, contains a reference to an unmanaged COM object that handles communications with the database server.
Specifically, you should explicitly dispose those SharePoint objects that implement IDisposable when you are finished using them.
Which is the Dispose method in.net framework?
The Dispose method calls the object’s Close method. We recommend calling the Dispose method, instead of Close, because SPWeb and SPSite objects implement the IDisposable interface, and standard .NET Framework garbage collection calls the Dispose method to free any resources associated with the object from memory.
This best practice addresses the issue identified by the SharePoint Dispose Checker Tool as SPDisposeCheckID_220. You must be cautious and aware of what the runtime is doing whenever you combine SharePoint object model calls on the same line. Leaks arising from this scenario are among the hardest to find.
Both messages point to cases where memory is being wasted because of incorrect disposal of SharePoint objects, and both relate to the number and state of SPRequest objects on a single thread: “An SPRequest object was not disposed before the end of this thread.
How are spcontext objects managed in SharePoint framework?
SPContext objects are managed by the SharePoint framework and should not be explicitly disposed in your code. This is true also for the SPSite and SPWeb objects returned by SPContext.Site, SPContext.Current.Site, SPContext.Web, and SPContext.Current.Web.
When does spsite get the date and time?

Is the lastcontentmodifieddate property of the spweb class?
Microsoft makes no warranties, express or implied, with respect to the information provided here. The LastContentModifiedDate property of the SPSite class is a System.DateTime object that gets in Coordinated Universal Time (UTC) the date and time when the content of the site was last changed.
The SharePoint Foundation 2010 and SharePoint Server 2010 object models contain objects that implement the IDisposable interface. You must take precautions when using these objects to avoid their long-term retention in memory in the Microsoft .NET Framework.
