Could Somebody please help me to understand truth tables, boolean expression, and von neumann architecture? Just an explanation to help me grasp it easier.

Math/ Computer Sci 
PsyDAG,
Since this is not my area of expertise, I searched Google under the key words "'truth tables'" to get these possible sources:
http://en.wikipedia.org/wiki/Truth_table
http://www.math.csusb.edu/notes/logic/lognot/node1.html
http://hyperphysics.phyastr.gsu.edu/hbase/electronic/truth.html
http://www.rwc.uc.edu/koehler/comath/21.html
http://mcckc.edu/longview/ctac/ttable.htm
You can find the other information you desire by yourself, if you use appropriate key words to do your own search for the remaining concepts.
I hope this helps. Thanks for asking.
