Instructor: Hey, welcome to the section
on Other Services.
So this is just to tell you
that these are going to be random services
that may appear at the exam, maybe on one question.
Sometimes a little bit of information
you need to know on these services is really, really tricky.
But bottom line,
I'm going to show you what you need to know,
and I think just by learning and listening to this lecture,
when you see the question at the exam,
you will remember the lecture
and you'll be good to go.
So I wish you happy learning,
and I will see you in the section.
