Endpoint

An endpoint is the address to a service, typically a target URL (including a port number, if applicable), which communicates with the network to provide its services.

For example, for the following URL:

http://maps.googleapis.com/maps/api/geocode/xml?address=Rio&sensor=false

the endpoint is

http://maps.googleapis.com

and the rest of the URL is paths and parameters to addess specific services and functions.
