associating
See filename-extension mapping.
authentication
Determining if a user has permission to access a resource or perform an operation.
bandwidth control
Setting the maximum capacity that a service is allowed to use. Deliberately limiting a servers Internet workload by not allowing it to receive requests at full capacity, to save resources for other programs such as e-mail.
