Talking to someone who is not technical about some technical details requires some extra skill. I've learnt that in my years of being in the technical side of things, I don't have that skill. That extra knowledge of what you should say so that they can understand you. I left that up to the others who possesses this skill.

It is really hard for me to explain some details in a way that everyone can understand. But giving examples from aspects of life they know while explaining is helpful. Like everyday stuff. Just try to come up with an applicable example. Note: if your example doesn't make sense, they will be more confused. Risky....
