Key Differences

Volatile Memory, such as RAM, loses all stored information when the device is powered down, whereas Non-volatile Memory, like SSDs, retains data even after the device is turned off. Each serves unique roles in computer architecture, providing temporary data storage or long-term preservation, respectively.

Cost variations are notable between Volatile Memory and Non-volatile Memory. Volatile Memory is often more affordable but requires continuous power and doesn't offer long-term storage. Non-volatile Memory, conversely, is typically costlier, attributable to its enduring data preservation characteristics.
