Hello Fernando,
Hope you are fine...
-> Well, I need to get information about communications' protocols,
-> about networks' configurations (token ring, star (?), and so on...)
-> and about how
I hope that I can help .... I will discribe one of the above ones for
you... I will discribe the commnication Protocols...
        The meaning of protocol in a communication world is the same
meaning of it in our real world. I meant by saying that to say..
Protocols is rules to govern the traffic of the information for one
place to another.
I will give you one example of the protocols... it is the CSMA/CD or
Carrior Sense Multipe Access with Cerrior Detect. That protocol is used
by the Bus topology networks like Ethernet. The method of that protocol
is as the following:
        * Sense the Carrior... if there is no one using it ... so send
the needed data but if it is used wait for some arbetarary time till it
becomes free.
        * When the carrior becomes free... send the packet and keep
sensing the carrior till you make sure that there is no one sending
another packet with you at the same time.... after making sure of
that... keep sending the packets till you finish the whole job.
        That is few things about the protocols in Communication I hope
that I add something to what you know about them. Also, the example is
only one exammple of alot of the known protocols.
I hope also the my message is not late.... because we Just join the
World Via FIDO services.
Take care and I am watting to read for you.
