Dashlets and Subpanels

This may sound like a still question but I am having problems understanding what Dashlets and Subpanels are. Could someone explain these to me? Thanks

Dashlets are those boxes that you can add to your Dashboard (e.g. “My tasks”) directly after logging in.
Subpanels are found in the DetailViews (below the actual record), there they show related records (e.g. the contacts of an account, or the mails exchanged with a contact).

@pstevens Thank you for the images. Very much appreciated and helpful to understand visually.
