Computer Architecture and Maintenance (G-Scheme-2014)
contrast to the other I/O devices, the AGP port is connected directly to the north 
bridge, because it has to be as close to the RAM as possible. The same goes for the PC 
Express x16 port, which is the replacement of AGP in new motherboards.
Q.Why the name given North and South Bridge
Ans. The name is derived from drawing the architecture in the fashion of a map. The 
CPU would be at the top of the map comparable to due north on most general purpose 
geographical maps. The CPU would be connected to the chipset via a fast bridge (the 
northbridge) located north of other system devices as drawn. The northbridge would 
then be connected to the rest of the chipset via a slow bridge (the southbridge) located 
south of other system devices as drawn.
Q.How North bridge plays important role in over clocking
Ans.  The   northbridge   plays  an   important   part   in   how   far   a   computer   can 
be overclocked,   as   its   frequency   is   commonly   used   as   a   baseline   for   the   CPU   to 
establish its own operating frequency. This chip typically gets hotter as processor speed 
becomes faster, requiring more cooling. There is a limit to CPU overclocking, as digital 
circuits are limited by physical factors such as propagation delay which increases with
