RAM is nothing but the form of Computer Data Storage. It is used for Operating system to perform the logical operation. DDR 2 is the previous version of the RAM and DDR 3 is advanced version of the same. It is noticed that DDR 2 is giving the 30 % reduction in performance compared to DDR3. All you need is compatible motherboard with RAM slot to place the DDR2 and DDR3 RAM in it.
