Subject: Please Do Not Throw Sausage Pizza Away...

Hi 023 (Microcomputer Systems) students,

      Here is my web page:  http://www.cns.uni.edu/~jacobson

           Class web page:  http://www.cns.uni.edu/~jacobson/c023.html
                                                             ---------

Please Do Not Throw Sausage Pizza Away and the SEVEN layers
                                 of the OSI Networking Model.

     links to http://www.cns.uni.edu/~jacobson/secure/LayersOSI.htm

     You can look at this powerpoint slide show ahead of time, if you
     want to preview it, but it will take several weeks and many exercises
     and explanations BEFORE it all makes sense, especially subnet masks:

        PowerPoint Slides: IP addressing, subnet masks and IP numbers.

     I'll suggest that you read pages 16-18 of the textbook for now,
     to supplement the material on the OSI Seven Layers.

     I will install the textbook CD ethereal on my own laptop computer
     during one of the next couple of classes, so you can see how that
     is done.  At that point I can start demonstrating a few things
     and having you try them out too, after you install the textbook
     network packet sniffer software on your PC, if you have access to
     one.  If the Physics building is going to be a problem, I will
     get Viv to install it on our Wright Hall network, so we can use
     it in some hands-on computer lab classes here.

     Mark
