How Do You Store Data?

Data that is actually being processed by the computer is stored in high-speed, electronic memory. This memory is directly accessible to the computer's central processing unit. However, its capacity is limited, and it is erased when the computer is turned off. The actual storage method consists of tiny electrical charges in microscopic capacitors. The capacitors lose their charge rapidly without refreshing, which is why the memory goes blank when the computer is turned off.
