         Federation and successor to the Soviet KGB; formerly led by
         Vladimir Putin [syn: Federal Security Bureau, FSB,

FSB

    (FSB) The bus via which a processor
   communicates with its RAM and chipset; one half of the
   Dual Independent Bus (the other half being the backside
   bus).  The L2 cache is usually on the FSB, unless it is on
   the same chip as the processor [example?].

   In PCI systems, the PCI bus runs at half the FSB speed.

   Intel's Pentium 60 ran the bus and processor at 60 MHz.
   All later processors have used multipliers to increase the
   internal clock speed while maintaining the same external
   clock speed, e.g. the Pentium 90 used a 1.5x multiplier.
   Modern Socket 370 motherboards support multipliers from
   4.5x to 8.0x, and FSB speeds from 50 MHz to a proposed 83 MHz
   standard.  These higher speeds may cause problems with some
   PCI hardware.

   Altering the FSB speed and the multiplier ratio are the two
   main ways of overclocking processors.
