Subdomains are a way of creating separate accounts within your master account, which are accessed as separate URLs. For example, you could set up a "timber" subdomain on your master account "hardware.com", which would be accessed as "timber.hardware.com". A lot of larger businesses use subdomains to establish branding and focus on separate product lines, because a subdomain creates a separate URL and web presence. However, you do not create a new CPanel when you create a subdomain. You still perform most administration functions for the subdomain through your master CPanel.

In practice a subdomain is a sub folder within the public_html level of your account that has 3. its own cgi-bin directory. The "timber" example above creates a new top-level folder called timber, with a cgi-bin sub-folder. Upload your files for the subdomain to this location, including a separate home file (such as index.htm).

Currently you can not create email accounts with the subdomain extension. A workaround for this is to create an account called "sales-timber@hardware.com", or similar.
