    RAM is for things the computer is working with at the moment, the hard drive is for storing files. The hard drive is too slow to work with information effectively in real time which is why we have RAM.

    Ya the Hard Drive is like your storage or Refrigerator...
    and RAM would be your lunch bag lol.

    Well no one really needs a huge lunch bag so 2gb would be great for RAM.
    On the other hand, how big you want your refrigerator/hard drive, depends on how much you're going to put in there.
    HAHA my analogy is weird!

    That IS a pretty nifty way to say it !

    So back to the main question
    Ram = Random access memory, its fast and expensive, and based on flash memory, which is quick and reliable, but looses stored data after a power loss! so if you turn of your pc, your ram losses all its information!

    Hard drive= A aluminum(in sata) plate which Spins, you can store lots of information on this on the cheap!

    SSD, also based on flash mamory, no moving parts but more expensive than a aluminum plate, but Very fast! Its the Future... its saving energy as well because of no moving parts! :apple:

    think of a hard drive as a film studio, they make hundreds of movies, to take up hundreds of gigs on a computer - But then you have your single movie, which take up only about 1-2gb (theoretically speaking or in blu ray.) Now you wouldn't watch hundreds of movies at once, would you? No that's just silly, you'd just watch one, which takes up the majority of your RAM.
    aka HD - hefty stuff RAM - how much your computer can use at once.
