Thanks for your question. Since Intel produces many different types of CPU, there is no one answer to fit all. For example, some CPU have pins that insert into a socket and others have bumps or BGA (Ball Grid Array) and the pins are in the socket.From a very basic point of view, all CPU contain some combination of address, data, power, clock, and other synchronization connections. If you were interested for example in the Pentium 4 CPU, here is the http://www.intel.com/assets/pdf/datasheet/310308.pdf Specification that will explain all the pin connections. Then when you want to take the next step, visit the http://support.intel.com/support/processors/ Intel Processor Support Page and dig into some of the more advanced multi-core designs such as Core2, XEON, and Itanium. Please let us know if this helped to get you a good grade in your class.
