These created under domain names. Many free webhosts you to use a sub-domain to host a website. Example you could create a sub-domain called "mine" on the domain mysite.com and it would become mine.mysite.com

A web page address within a primary domain that points to a sub-directory within the primary domain. For example, aol.com is a domain. netfind.aol.com is a sub-domain, or subdirectory within the aol.com domain. The reason you can get to aol.com without typing http://www.aol.com (you can type simply http://aol.com) is the “www” is the default sub-domain of the primary domain of aol.com. Table One or more rows of cells on a page used to organize the layout of a page or arrange data systematically.

Each domain name can have unlimited number of sub-domains, which are specified by DNS entries for the domain name. "www" is one DNS entry that nearly all domain names include. Other popular ones include "ftp" ( ftp.yourdomain.com), "secure" ( secure.yourdomain.com), etc.

Subsidiary website linked to and dependent upon the primary domain website

A directory named before the root web address, for example crawler.archive.org (crawler is the sub domain).

A sub domain, also called a third level domain, allows you to use a URL such as http://subdomain.mydomain.com to point to any directory on your site. The great part about using subdomains is that it can allow you to have multiple sites under one domain name and it can also make it easier for you and your readers to access parts of your site. For example, I have a part of my website where I present some of my writings. For a user to view this area they have to go to: http://www.eclectic-world.com/personaltouch/writingattempts/. Using a third level domain, I could make it much easier by having http://writingattempts.eclectic-world.com point to that very long URL. Most hosts now offer subdomains, with many including a set number with the account for free.

A partition within a domain name, usually a third level domain name.

A part of main domain that does not include "www". For e.g. http://help.mydomain.com , here "help" is subdomain.
