What type of memory does not retain data after the removal of power?

Volatile memory is characterized by its inability to retain data when the power supply is removed. This type of memory is used in applications where speed is essential, such as RAM (Random Access Memory), because it allows for quick access and writing of data while the system is powered on.

When the power is turned off, the stored data is lost, making volatile memory suitable for temporary storage during active processes but not for long-term data retention. This is in contrast to non-volatile memory, which retains data even when powered down, making it vital for permanent storage. Therefore, the nature of volatile memory is key to understanding its role in computing and network systems, especially in contexts where immediate data access is required but long-term storage is not a priority.
