svn Difference betwenn BASE & COMMITTED

Question

please tell me in which situation BASE and COMMITTED revisions can have differences?

We can read in docs:

COMMITTED -- The most recent revision prior to, or equal to, BASE, in which an item changed.

But I can't understand why we need special name COMMITTED (what is that moment when it isn't like BASE?)

Answer 1

The BASE revision is the last revision your working copy was checked out or updated to where as COMMITTED is the last change to a file or folder.

If you check out a repository at revision 10 you'll have the BASE of 10. if a file in that repository was last changed at revision 8, it will still have a BASE of 10, but the COMMITTED will be 8, as that's when it was last changed.
