Wow. Talk about mean. The north and south bridge are parts of the chipset that....regulate....the transfer of data betwean every part of the computer. The north bridge connects to the CPU, RAM, possibly the back panel connections (not 100% on that), and to the south bridge. The south bridge connects to the north bridge, hard drives optical drives and the like, and the PCI and PCI-E slots. I'm shour some of that is wrong but it should give you a general idea.
To the rest of you. can you say that you always knew what a N/S bridge was? Or even a CPU? If you say yes then you are lying. When you were five years old you probably could not say north, south, or bridge correctly so don't be so harsh. It is a little surprising for someone that has posted so much but he may not be posting on this part of the forums.
