Detailed explanation-1: -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-2: -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-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. Volatile memory has several uses including as primary storage.
Detailed explanation-4: -RAM is volatile memory, which stores data in a single transistor and capacitor. This means it needs a constantly recycled charge to hold its data. If the power is turned off, it cannot refresh the data and it is lost. This is known as DYNAMIC memory.
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.
