Hi, Don't know how much you know but this is the basics for all protocols.
Information is segmented (divided) into small units call PDU's. They are modulated in some form, over ADSL or radio uning a modulation. Modulation is a way to transfer a number of bits in an efficient way and so that even when errors happen they can be reconstructed.
OK. The small segments when received by the receiving side are checked for errors and if OK passed on to the user. at the same time same form of Acknowlede can be send back to the sender indicating all was fine and the next unit (PDU) can be send.
etc...
This is the basic behind protocols. Its nothing more than a standard of how you communicate. Pleople also have a protocol. They talk. Listen abd talk, ask if you can repeat if they don't understand you well.. etc..
hi PaulHolland
