ELI5: Autism

I can't find a clear source on what autism is or how it 'works'. Everything I find pretty much says "Autistic people are shy and quiet, unless they're not, in which case they are loud and bombastic, unless they're not, in which case they're socially the same, but good at something, unless they're not in which case...."

What is Autism, what are its types, how are they different from one another, and why are the different types not just considered different conditions?

Real oversimplification for eli5:

Autistic people process information on people with the 'objects' part of the brain, instead of the 'social' part. Thus, social norms and effects of ones behaviour on others are not considered, relevant or even understood.
