Detailed explanation-1: -Random Access Memory is volatile. That means data is retained in RAM as long as the computer is on, but it is lost when the computer is turned off. When the computer is rebooted, the OS and other files are reloaded into RAM, usually from an HDD or SSD.
Detailed explanation-2: -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.
Detailed explanation-3: -Volatile memory, in contrast to non-volatile memory, is computer memory that requires power to maintain the stored information; it retains its contents while powered on but when the power is interrupted, the stored data is quickly lost.
Detailed explanation-4: -4 ROM. Non-volatile memory is memory that retains its values even when power is removed. Earlier forms of non-volatile memory included various forms of read-only memory (ROM).
