When I'm looking at "System Information" on Windows OS I can see two fields which have the same values. Computer name and Full computer name.

So what is the difference between "Computer name" and "Full computer name"?

If you're part of a domain, the Full computer name would include your computer name with the domain name appended to it.

For example:

If I join a domain called mydomain.local and my computer name is MyPC, Computer name would show MyPC and Full computer name would show MyPC.mydomain.local. Because you're not part of a domain, both entries just show your computer name.

If you added a server to your network, you could enable Active Directory and Domain Controller services on that server to allow computers on your network to join the domain it controls. Once connected to the domain, the Full computer name entry would show your computer name including the domain name you chose when you setup the (Hypothetical) Server.
