For example:• The Application Layer prepares its data and hands off to the PresentationLayer• The Presentation Layer formats the data in a way that conforms to itsprotocol• The Session Layer adds a label to the data that identifies the“conversation”• The Transport Layer breaks the data into segments, tags each segmentwith an order number and, perhaps, a checksum• The Network Layer takes the segments and creates packets that containinformation on the source and destination of the machines that arecommunicating• The Data Link Layer takes the packets and creates frames that are compatiblewith whatever physical medium it may be using• The Physical Layer receives the frames, converts them to bits (binary digits;more on this later) and physically sends the informationBrocade IP Primer 7
