Depending on what you wish to do with you'r computer/laptop, higher ram is better.
depending on how high you go, though, it can be bad. Higher ram uses batteries faster, and if it is way to high your computer may not be able to wowk with it.
DDR2 RAM is SDRAM. It provides double the bandwidth of DDR RAM, but at a higher latency. DDR3 is much better than DDR2 performance-wise, and it uses less voltage.
I take it that the 1.5 is in GB since no computer can run on 1.5MB of RAM. So the 1.5GB is higher that the 512MB RAM.
DDR3 runs at higher clocks and lower voltages due to a more complex 90nm manufacturing process than DDR2 Ram. So therefore, DDR3's main difference in comparison to DDR2 is better power usage and higher clock speeds.
RAM. Better speeds and better performance overall.
Obviously a monkey is better than a ram.
Hz on a RAM is the speed of which the hardware can read. the higher the Hz the faster RAM.
8GB is better. The higher the number the more it is, and the more it can store. In computers, the more RAM you put in (Assuming you are talking about RAM) the faster and better the computer will perform
Both Are better Lower latency means that the Ram is quicker and better for games More Ram is better for running lots of programs at once because they take up more space
More ram the better, if you have the money why not.
It's not a problem. But it's better when FSB frequency is higher than RAM frequency.
Because of the needed calculation speed more L2 is better. More FSB would be better for presentation of 3D-Models or environment in realtime. But in rendering the GPU does not matter nor does the FSB. It is only L2 and RAM ! Because of the needed calculation speed more L2 is better.

Yes, you can add two higher-size RAM cards to the laptop.
