hostname

This question already has an answer here:

localhost as hostname confusion 1 answer

I have a basic understanding about hostname and FQDN. Now I am confused, do I really have to specify a name for my hostname? So for example:

Hostname: somename
Domain: mydomain.com
FQDN: somename.mydomain.com

Now, I see something that the hostname is localhost. What is the difference and impact of that? So my FQDN if localhost is my hostname would be localhost.mydomain.com, right?
