Not able to understand NLP

I am not able to understand NLP as it has been completed in a very concise manner.
Can someone help me or shall I go ahead and further things will be more clear?

I would suggest going back over it again until you understand what’s got you stuck (take notes, seek out other sites & explanations for concepts etc.). I’m not sure that moving forward is a good idea if you’re confused b/c it might make you more confused.

Also, remember, if you’re stuck on something, post a question here. Sometimes if someone explains a concept in a different way it’ll make more sense.
