-So-dimm (use in laptop, smaller than dimm)
-Dimm (use in desktop)
Dimm type:
(1)Sdram (old type pc system)
-can be categorised into PC100 and PC133.
-has 168 pin.
(2)Ddr Sdram (also known as DDR1)
-has 184 pin
-can be categorised into PC1600 (DDR200), PC2100 (DDR266), PC2700 (DDR333), and PC3200(DDR400).
(3)DDR2 Sdram (known as DDR2)
-the new type of ram
-has 240 pin
-faster than ddr and sdram.
-can be categorized into PC4200 (DDR533), PC5300 (DDR667), and PC6400 (DDR800).
