Memory

There is not a difference.

PC-100 is a type of SDRAM.

For further explainations and comparisons of memory goto the following web sites:

The PC 100 modules are backwards compatible, but if your computer won't benefit from using a PC 100, it is not recommended. If you are planning on upgrading your motherboard to one that supports PC100 modules and you know it will fit both motherboards, you can upgrade with it.

Hope this helped!

SDRAM is often rated in megahertz speed rather than nanosecond cycling time. SDRAM-100 is 10 nanosecond speed. Intel has created PC/100 and PC/133 standards that define the performance criteria that a 100MHz memory module to be reliable in a computer with 100MHz bus speed (ditto 133MHz). To meet the criteria with enough overhead to spare, most PC/100-certified memory will be 8ns or 125MHz. Intel feels that the margins are too close for 10ns memory to be reliable at 100MHz.
