Detailed explanation-1: -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-2: -Volatile memory is a type of memory that maintains its data only while the device is powered. If the power is interrupted for any reason, the data is lost.
Detailed explanation-3: -In general, volatile memory needs power to maintain the stored information. In contrast, the stored information is retained in nonvolatile memory when the power supply is turned off.
Detailed explanation-4: -Your computer’s RAM loses its data when the power goes off. Your computer has different kinds of memory, some of which saves its data when you turn the power off, some which does not. Computer scientists call the former kind of memory non-volatile and the latter volatile.
Detailed explanation-5: -Non-volatile memory is a category of memory that retains its data even when the system is turned off or the power is off. It is sometimes referred to as static or permanent memory. For example, hard disk.
