RAM (Random Access Memory) is the primary workspace of a computer. It stores the data and instructions that the CPU is actively using. It is designed for high-speed reading and writing, but it cannot retain data without a constant electrical charge. In computing volatile memory is a type of storage. It needs power to keep the information stored. If the power goes out or you turn off the computer all the data, in memory disappears right away. Volatile memory loses all its data when the computer is shut down.
