RAM is volatile memory, which means that the information temporarily stored in the module is erased when you restart or shut down your computer. Because the information is stored electrically on transistors, when there is no electric current, the data disappears.

Each time you request a file or information, it is retrieved either from the computer's storage disk or the internet. The data is stored in RAM, so each time you switch from one program or page to another, the information is instantly available. When the computer is shut down, the memory is cleared until the process begins again. RAM allows the computer to read data quickly and efficiently to be able to run applications efficiently, whereas ROM stores the program required to initially boot the computer and perform diagnostics.

RAM is a common type of memory found in computers and printers, and can go up to a few gigabytes. ROM is usually only a few thousand bytes of storage in personal computers.

RAM is primary memory and volatile. Static RAM is more expensive and has more capacity for storage than dynamic RAM that has to be refreshed more often, and is thus slower. ROMs are integrated circuits that contain data and most often cannot be altered. Share this comparison:. What is the difference between an input and output device?
