How is it called when you use "mail" in "mail.google.com" for example?

I know it is probably a dumb question, but I don't know how to refer to it.

How is it called when we use the subdirectory comming first in the URL and how is it configured? Is it something configured on the server?

It's called subdomain and it's configured as a DNS entry and Web server listens requests to the whole subdomain.

Some domain registrars have DNS host record configuration, where you set up - for example - mail.youdomain.com for a given IP address. Finally, domain registrar's DNS server points to the configured IP address, and Web server receives a request with that IP address and the mail.youdomain.com host name to identify which Web site should be served to the client (f.e. a Web browser).

Configuration may depend on the Web server technology (i.e. Apache, IIS, ...).
