My two friends and I were planning to buy Memory Upgrades for our computers. I own an Apple Mac Computer, so I need to buy the Apple Mac Ram Memory Upgrades. My friend wanted to buy what they called SO-DIMM iMac Memory then, my other friend chose Toshiba SO-DIMM Memory. One time my friend asked me why we need to upgrades the memory of computer, and what it is. Then I told her that these memory upgrades help and increase the overall performance of the computer and adding Random Access Memory or RAM is just an easy step.
However, not all RAM is just the same. According to the research to have to know if your computer used DDR or DDR2, this is a 2 type of Random Access Memory, this memory should fits on the computer so it will work together. You must also know the manufacturer of your computer.
