RAM only holds memory/data wen the pc is switched on, wen its switched off then all the data which was on the RAM gets cleared, so if u take the RAM out there is nothin on there
What there all trying to say is, (RAM) Stands for Random Access Memory basicly it stores only when an application or any application is running, it's what runs the programme, then as you switch it off it is erased. hence the Random part of it.
