    On your hard disk? Commented Apr 16, 2017 at 17:50
  • RAM is not the opposite of ROM (ROM can be RAM). Commented Apr 16, 2017 at 17:54
  • ROM is used only for firmware--very low-level instructions for interfacing with the hardware or initiating starting the computer. RAM is used for active temporary storage. Anything that needs to be preserved is stored on "permanent" media like a hard disk or SSD or externally on a flash drive or optical disk (or other external drive). Tablets often use flash memory internally rather than a drive for permanent storage. Commented Apr 16, 2017 at 18:26
  • When you save you save on Hard Disk, Like you said when you run a program or edit something it is done in RAM (temporary) when you Turn off the Laptop it is gone, ROM is like what fixer1234 said for booting and low-level instructions not for running programs Commented Apr 16, 2017 at 18:53
