Q.What is Chipset?
Ans.  A   number   of   integrated   circuits   designed   to   perform   one   or   more   related 
functions. For example, one chipset may provide the basic functions of a modem while 
another provides the CPU functions for a computer. Newer chipsets generally include 
functions provided by two or more older chipsets. In some cases, older chipsets that 
required two or more physical chips can be replaced with a chipset on one chip. The 
term is often used to refer to the core functionality of a motherboard. 
On a PC, it consists of two basic parts -- the northbridge and the southbridge. All of 
the  various   components  of   the   computer   communicate   with  the   CPU   through  the 
chipset.
The northbridge  connects   directly to  the   processor  via  the  front side   bus  (FSB).  A 
memory controller is located on the northbridge, which gives the CPU fast access to the 
memory. The northbridge also connects to the AGP or PCI Express bus and to the 
memory itself.
