What term describes a PC card that can be inserted or removed without rebooting the computer?

The term that describes a PC card that can be inserted or removed without rebooting the computer is "hot-swappable." This capability allows users to add or remove hardware components while the system is running, which is essential for enhancing usability and minimizing downtime. With hot-swappable devices, the operating system recognizes changes in hardware configuration and updates accordingly without requiring a restart.

This is particularly useful in environments where maintaining continuous operation is critical, such as servers or workstations that require uninterrupted service. In contrast, while "Plug and Play" refers to the ability of the operating system to automatically detect and configure hardware, it does not specifically imply that the device can be inserted or removed while the system is running. The other terms may refer to different types of hardware behavior or configurations but do not convey the hot-swap functionality inherent to the correct term.
