For example some minecraft servers have a domain that starts with 'mc.xxxxxxx.com' In this case the domain starts with mc. So what does the mc. Mean and where does it come in?
What are the first few letters in front of some URLs?

It identifies a server (or a group of servers) owned by that domain.
With a small web site, the domain points to a server. In a large one, different servers perform different functions e.g. Sales.myco.com, product.myco, com, api.myco.com.

It identifies different websites within a domain. Not necessarily different computers as there can be more than one website per computer.
A domain owner can also create subdomains and sub-subdomains more-or-less without limit, so you could have websites called a.sales.example.com and b.sales.example.com, or silly things like jerry.gow.is.an.idiot.example.com
