Hi Basic person,
erm.. not being funny but sure the first thing you would do know would be wikipedia it?
eg : http://en.wikipedia.org/wiki/Pentium_4 It has a good overview.
Also if you go to http://support.intel.com/support/processors/ andd pick one of the various P4, you will get a more in depth and techincal view from all teh datasheets and technical product specifications.
Aslo you could try this one
I hope you wern't expecting someone to do your school assignment for you...were you?becasue if you were you need to pay for that type of service
Hope this helps
