Front Side Bus (FSB)

Front Side Bus

FSB refers to the bus that connects the CPU to the system Memory.We also know it as SYSTEM BUS or MEMORY BUS. It helps to measure the speed at which the CPU communicates with the RAM(Random Access Memory). The work of FSB(Front Side Bus) is to connect the CPU to the north bridge of the motherboard.
The North side bridge Comprises the memory bus, PCI(Peripheral Inter Connect) Bus and the AGP (Accelerated Graphic Ports)Bus.FSB speeds range from 66MHz to 1333MHz.
The Speed of FSB(Front Side Bus) can also be set up by using BIOS(Basic Input Output System) setup Program.The Jumpers on the Motherboard also helps to setup the speed of FSB(Front Side Bus).
FSB(Front side Bus ) also describe the communication system between L2 Cache & processor to the Motherboard.

But In latest there is no FSB(Front Side Bus) as the memory Controller it's inbuilt in Processor.
