Related to memory

I might be wrong, but I'm pretty sure the processor accesses the hard drive to put that data into the RAM. RAM stands for Random Access Memory and can be changed and manipulated. Once manipulated how it needs to be, what is stored in the RAM can then be pushed back onto the Hard drive. The RAM is pretty much an "18 wheeler truck" filled with information that goes back and forth between the HDD and the CPU. The more RAM you have, the more you can get from the HDD and manipulate before dumping back onto the HDD.

if you need a more in depth writeup on this, you'll need to address a computer engineer.
