What type of storage is referred to as non-persistent storage?

Non-persistent storage is also known as temporary storage. This type of storage retains data only during the session or process in which it is used and does not save data long-term. It is typically associated with resources that can be cleared or wiped when they are no longer in use, such as RAM (Random Access Memory).

In contrast, options that suggest permanence, such as permanent storage and flash storage, are designed to retain data even after power is turned off or the session is ended. Network storage can also be permanent, as it generally involves storing data on a server accessible over a network, maintaining the data regardless of the user's session status. Therefore, temporary storage is the most fitting category for non-persistent storage, since it is meant for short-term use rather than long-term data retention.
