Random-access memory (RAM) is a type of computer memory that allows data to be read and written in the same amount of time, regardless of the physical location of the data inside the memory. RAM is a "volatile" type of memory. This means that stored information is lost if the power is removed. Therefore, it is likely that Jack's presentation was located in the RAM memory, as it was lost when he switched off his computer unknowingly.

Random Access memory (RAM) stores data temporary until the computer is switched off
