A subdomain is second website that has the same domain name, although it as different content and also a different www address. Let’s say for example that the original site is www.qwerty.com. The subdomain can be forums.qwerty.com, help.qwerty.com or even contactus.qwerty.com

An add-on domain is also second website and also has its own unique content. However, this type of domain requires you to register it under a new domain name before you can start hosting it.

How to upload files to an add-on or subdomain
There are two ways you can do this via File Transfer Protocol
Enter the following information in a FTP client:
Host = add on domain name
User = firstname.lastname@example.org
Password = (your password)
Port = 21
After you have successfully connected to your ftp client, you should see a folder called cgi-bin that contains your files.
You can also use your cPanel data to transfer files.
Host = primary domain name
User = cPanel username
Password = cPanel password
Port = 21
After you do this it should show up in your home directory. Just double click the public_html folder and the add-on domain folder.
