This may sound like a silly question but, what are these UUIDs/GUIDs used for? And what is the actual difference between the two?

This may sound like a silly question but, what are these UUIDs/GUIDs used for? And what is the actual difference between the two?There is a minor difference in the final section of the ID.
I believe the difference is related to MS-specific overloading of the terms :D

They can be used to create an ID (for an object/item/thing) that will be
reasonably unique across both time and space.

eg, 2 folks creating blog posts that will be stored in the same table.
Their uuids will have a reasonable expectation of being dissimilar
(a useful feature of an ID :D)

Personally, I prefer a hash of time and spatial/identity info.
The nominal comparability of UUIDs isn't necessary, since
a better design is to store the time-related info separately anyway
(mind you I've gone that other road many times :) ).
