The computer system has two types of memories in general; one is called volatile and the other is non-volatile. The word volatile is used for these devices because of their temporary or permanent data storage capacities. Memory means the data storage capacity in a device. Like we have brain a part of it is volatile and a part of it is non-volatile, how? This will be easily understood after reading the characteristics of the two memories of the computer system. Volatile Memory A device or a memory device in the computer that needs current to work and keeps the record or data in it is called volatile memory. As its name suggests it need current or electricity to work and to keep the record in it once the current is cut down the data disappears.
