Modern motherboards come with a built-in LAN controller.

What happens when I am using a GPRS modem - does it involves the usage of that LAN controller in any way?

If somebody could explain the procedure a little bit ? – Torpido Aug 20 '11 at 14:40
Do you have any make/model of GPRS modem in mind? If so, the interface specs can be checked. – Linker3000 Aug 20 '11 at 15:00
@Linker3000 Modem uses USB interface. – Torpido Aug 20 '11 at 16:31

Depends on the GPRS Modem in question!

If it is a GPRS card modem for a laptop (Express Card/similar) or desktop(PCI Express), the answer will be no.

If it is a GPRS Modem that has only a network card port, the answer will obviously be yes.

..and the last GPRS/GSM modems I used had serial port interfaces – Linker3000 Aug 20 '11 at 14:59
@William Hilsum I think i was not able to explain the question properly. What i wanted to ask was, what happens when a GPRS modem retrieves some data from the internet , does it gets processed by the processor directly or NIC has any role to play in it ? – Torpido Aug 20 '11 at 16:42
Depends entirely on the device. Is it a software based card (in which case, the pc will do nearly all the work) - is it a hardware based card (in which case, the computer will do a lot less), is it a modem, in which case it will do all the processing and just pass on the ethernet traffic. – William Hilsum Aug 20 '11 at 16:45
@William Hilsum Its a CDMA Modem, with USB interface. – Torpido Aug 20 '11 at 17:21
