www.merriam-webster.com is pretty much the go-to online dictionary of choice these days, and it offers a full 10 different categorical definitions for the word domain, but most people will understand it to mean ‘space thats yours.’ The prefix ‘sub-‘ generally indicates a state of being beneath or under the suffix, whether literally or figuratively.

Subdomains are also used by free web hosting providers to resell web space under their own domain name (e.g. http://membername.hostname.com). Each member will have their subdomain, but every one of them there will still share the domain name of the hosting provider. Subdomain names are also practical to balance the web servers for a high traffic website. Multiple web servers are assigned different subdomains like www.sitename.com, www1.sitename.com, www2.sitename.com etc, though each of them contain the same application code.
