If you don't have a CS education or a lot of professional experience yet there's no logical reason to expect you just "know" things - even what is considered basic knowledge. It's okay to not know what you don't know, you just need to address that.

Seek education (either a CS course or the multiple online courses), seek the help of a mentor (someone at work? friend w/ more experience?) and keep working on getting more experience.

Don't think people are "born programmers" - the good people invariably sank a lot of time into it.
