What function do network cards perform?? I know they can link computers together.. but have they any other function?

That is about it - they "network" PCs. If you think of their full title, Network Interface Cards, (NICs) then you will see that they are the interface between machines.

So if you have a network card,do you need an external broadband modem?

No. What kind of broadband are you referring to? ADSL, Cable, ISDN?

A network card is just one method of linking together PCs, or peices of PC kit, that you want to link up.

My son had BT broadband using a broadband modem supplied by BT ... got a new computer..the guy who set it up (a BT guy btw) said he didnt need the external modem as there was a card installed in the new puter which did the business instead..got a wee green light flashing (just like a network card) at the back (hewlett packard job) ... so what kind of card is that?? just curious guys/gals

It could be an internal ADSL modem - look in Device Manager for more info.
