Could anybody please explain what "internalism" and "externalism" are in epistemology in simple terms?

I've read a few articles in various encyclopedias, but they seem to be confusing. Could anyone please explain in Layman's terms what "internalism" and "externalism" are in epistemology?

Internalism is the position that whatever makes the difference between a merely true belief on the one hand, and knowledge on the other has to be accessible though introspective reflection. In other words, in order for your justified belief to count as knowledge you have to be able to determine what makes your belief justified using reflection alone.

Externalism is the position that at least some beliefs that count as knowledge need not be such that their justification is accessible through reflection.

Does this help?
