It's OK everyone's a newbee at one time or other!
Your RAM is completely empty (100% free) when you first turn your compter on - it's only when windows loads, and then you load up programs such as internet explorer, Microsoft Word etc that it 'uses up' your memory. As soon as you close these programs they will free the memory again.
So in short, the amount of memory free at one time is only a reflection of how much you're doing on your PC at that time.
Also, it is like a car in that, you could say you have 5 people in your 300E and it has '0% space free', but actually with some squashing and moving stuff around you could fit another person in.
Then you could move some people into the trunk and fit even more in - it wouldn't ever be 'full'. However it takes time to move people into and out of the trunk.
Windows does precisely this itself, moves stuff around so that you're never full.
However in Windows, the inside of the car is 'memory' and the trunk is a 'Swap file'
The more memory, the less you have to do the slow 'trunk/swap file' stuff. So you could get more if you wanted your PC to be quicker while doing lots of stuff at once.
sorry if this is too much for you!
good luck
