Hello,

          Is this a proper forum to ask some fundamental questions on the IBM
PC - Ethernet Interface card (NIC) interface ? (hardware as well as software).

If not so : please skip reading this beyond this line with a  request for any
pointers to sources of information.

If so I would appreciate  some body suggest me  answers to following questions
? (some references journals etc also will do )

Hardware Questions :

         What kind of interface is generally used : DMA etc ? How does PC CPU
and NET CPU

talk to each other via extension slot ? Is there a speacial mechanism for
interface between PC and NIC : eg FIFO or custom built chips ?

Software Questions :

           Does this networking require a device driver to be written (in
order to interface to MSDOS)?

What is the usual interface to a programmer writing network applications :
such as telnet or tftp ?

Thanks Very Much,

-- Murthy.
