RAM actually keeps history of all of the applications you have opened on your computer. Once you turn off your computer these disks are wiped. (You can't store data on them [Even if you could, your data would get deleted]).

For every application you open on your computer the more RAM your computer requires. You might have noticed that if you have 20 programs open your computer will run really slow and if you have 1 or 2 open it will have brilliant performance. Some of this occurs because of Ram (Random Access Memory). When you open a lot of programs your computer asks for more RAM, and if there is not enough free RAM available it will compress your data.
