Picture that your computer is a house. The RAM is your floor space. Basically this is how many toys you can play with at a time. How fast you play with the toys is determined by your processor speed (measured in gigahertz). And your Hard Drive memory is how large your closet space is, basically how many toys you can have in the house. You can’t play with all of them at the same time, but the more floor space you have (RAM) the more you can do at one time. The more closet space (Hard Drive) you have, the more toys you can store to play with at different times.
