F#$@ NETWORKING!!

Yeah we learned about networking.  To preface this, it is horrible but i have to get these points so here we go.

How does an email get from one computer to the next?  Unfortunately now I know.  It is by the process of encryption and de encryption in turn.  The process has is the same but in opposite directions and it has seven steps.  They are Application, Presentation, Session, Transport, Network, Data Link, Physical.  The format of the data in each step is as follows respectively: Data, Data, Data, Segments, Packets, Frames, and Bits.  Each step has details about what it is and they are as follows: Application: Email and Browsers, Presentation:  common data format, encryption, and compression, Session: virtual session, end to end connections, Transport: Quality of Service and Flow Control,  Network: Routing, Data Link: Media Access Control, and finally Physical: bits.



Bye I have to go.
