Computer Architecture Questions
Volatile memory refers to a type of computer memory that requires a constant power supply to retain stored data. When power is lost, the data stored in volatile memory is also lost. Examples of volatile memory include RAM (Random Access Memory) and cache memory.
On the other hand, non-volatile memory is a type of computer memory that retains stored data even when the power supply is disconnected. Non-volatile memory is used for long-term storage of data that needs to be preserved even during power outages or system shutdowns. Examples of non-volatile memory include hard disk drives (HDDs), solid-state drives (SSDs), and flash memory.
In summary, the main difference between volatile and non-volatile memory lies in their ability to retain data without a power supply. Volatile memory loses data when power is lost, while non-volatile memory retains data even when power is disconnected.
