Which technology allows users to connect devices without shutting down the computer?

The correct choice, which refers to hot-pluggable technology, is appropriate because this technology is designed to enable users to connect and disconnect devices while the computer is still powered on and operating. This capability is crucial for maintaining the system's functionality and minimizing downtime.

Hot-pluggable devices typically include USB peripherals, network cards, and other components that can be added or removed seamlessly. With this technology, users can connect new devices, switch out components, or troubleshoot hardware without the need to restart the entire system, making it incredibly efficient in various settings, especially in environments that require high availability.

While hot-swappable technology is similar and often discussed in the same context, hot-pluggable specifically emphasizes the ability to do this without the requirement of any additional handling, such as ensuring the system is ready for the device to be added or removed. Cold-pluggable refers to devices that must be connected or disconnected when the computer is completely powered off, and warm-swappable usually involves scenarios where the system must undergo a brief transition phase, such as changing power states, making both unsuitable in this context.
