     With respect to PCs, FSB usually stands for Front Side Bus, a term
spawned after Intel introduced the 100 MHZ PII. FSB usually refers to the
speed that the processor talks to the rest of the system, in the case of the

PII it is 66MHZ for processors up to and including the 333MHZ, and 100 MHZ
for the PIIs above. The FSB speed is having less and less of a significant
effect than in the past due to the L2 cache is systems now being part of the

CPU instead of having to be accessed through the out bus. The next line of
Intel processors will have FSB frequencies of 133 MHZ, some higher, I
believe 150 MHZ. The K7 from AMD will use a FSB speed of 200 MHZ, since it
uses the SLOT A interface, however this is getting off topic... Hope this
helped, TTYL
