Which of the following media types is not hot swappable?

The DVD drive with an IDE interface is not hot swappable because IDE (Integrated Development Environment) drives, unlike their SATA counterparts, typically do not support hot swapping. Hot swapping allows you to remove and replace devices without shutting down the system or interrupting the power, and is a feature supported by the SATA interface due to its design, which allows for real-time data transfer and connection/disconnection of devices.

In contrast, devices utilizing the IDE interface were designed for a more rigid connection approach, where power and data connections would generally need to be terminated before removing the drive to avoid damage to the system or data loss. Thus, users would typically need to power down the system to safely remove an IDE device, making it non-hot swappable.

USB flash drives, external hard drives, and SATA DVD drives are designed to be removed and connected while the system is running, which is why these options can be hot swapped. This functionality contributes significantly to the convenience of using these types of media in various computing environments.
