What is the difference between 200, 204, and 240 pin RAM?

I'm looking for some Ram upgrades and I saw three different sizes, 200, 204, and 240 pin. I was wondering what the differences between them are. Is it speed? Can more pins transfer more info faster?

The difference in pins is more or less incidental.  There are several different types of RAM, all of which are incompatible with each other.  You need to find out what your motherboard takes and buy that type of RAM; the easiest way to do this is to look at the sticker on the RAM stick, searching for SDRAM, DDR, DDR2, or DDR3.

If you can't easily view the sticker, power the computer down and unplug it from the wall.  Next, hit the power button to drain any stray voltages.  Then, push the levers on both sides of the RAM stick at the same time; the RAM should pop up a bit.  Carefully handle the stick by the edges at the corner.  Replace the stick by pressing the top edge near the corners and push downwards so that both levers click into place.

4, 36 or 40 pins, more or less.

It's a socket-format, like CPUs
Match the RAM to your mainboard - look up your mainboard spec' or get out your paper-manual, see what it'll take and match your RAM purchase to that.
