what is north and south bridge?

waht is north and south bridge

North Bridge:
The chip responsible for communications between the CPU and the rest of the system, as well as the interface to the AGP bus and/or on-board video. In 32-bit systems, it is also responsible for the memory interface to control the RAM.

South Bridge:
In 32-bit systems, this chip is responsible for many auxiliary functions such as implementing USB and FireWire interfaces, Audio controllers, and ethernet controllers, as well as PCI bus interfacing, SATA controllers, and IDE interfaces. In many Athlon64 systems, the South Bridge is no longer present, as all its functions are in the North Bridge.

In case you don't understand what Enigmatic just posted, the North and South bridge are the parts of your motherboard that connect all of your computer components together.
