The northbridge typically handles communications between the CPU, RAM, AGP or PCI Express, and the southbridge.
Now, is the chip just a processor or does it include firmware if you will that controls it, telling it where to send the signals

THe bios controls the base functions of the motherboard.

The northbridge handles communications from the CPU directly to your ram RAM for intel.amd has on board mem controller built into it.this is why amd has no northbridge and only a southbridge

The southbridge handles communications from the cpu to AGP or the PCI Express slots\pci slots.

Its like a traffic lights , it makes sure that everyone useing these buses can send there data , also it lets the southbridge send its data via the northbridge.

Cpu is the boss , cpu gives rights to the northbridge to keep all the buses intact and keep them all flowing good and there are quartz crystals on the board to keep all the data flowing on a certain hearbet or mhz. Every component has like a ID number , well not one id but depending how many lanes they use it has that many ID numbers for there bus which they then transfer the data to the northbridge and wherever it needs to go from there.

i think. :)

firmware can be found on the following devices

Mboard (the firmware usually upgrades all associeted chipsets, raid etc)

CDrom/DVD drives

Graphics Cards - i haven't updated firmware on a graphics card for a couple years, but some do have updateable firmware.

Raid controllers (pci) tend to have firmware

Printers espcially network ones

but generally the 2 you have to worry about are motherboard & cdrom/dvd (lets you read more media types)

it acts as the bridge between cpu and HDD, RAM and VCARD.

Ahh, it always helps to Google a question first. I will stick with just Intel architecture for now. AMD was similar. Before the Intel I series chips, the CPU was connected to the Northbridge. That chip had the memory controller and the buss that connected to the south bridge. In addition, the graphics buss was connected to the north bridge. think of the bridge chips as major road interchanges. Data travels from the cpu to ram, data from an input travels from the south bridge, through the north bridge to the processor. When Intel came out with the I7, they put the memory controller inside the CPU and what they call, the Quick Path Interconnect between it and the IOH chip, formerly known as the South Bridge. Without going into any more detail, you can google computer architecture, north bridge, south bridge, memory controller and all kinds of computer stuff and get comprehensive answers to such questions.
