FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -You can use the hotplug command to manage hot pluggible connections, where a connection can be a connector or port, on PCI Express (PCIe) and PCI SHPC devices only. A hotplug connector is a physical representation in the system where a component is inserted or removed.

Detailed explanation-2: -PCIe Hot-swap allows an endpoint or one or more PCIe switches with one or more endpoints to be inserted or removed from a PCIe system grace-fully or unexpectedly without special consideration. In a Hot-swap environment, PCIe endpoint devices are connected to PCIe switches or to the root complex utilizing PCIe cables.

Detailed explanation-3: -The PCI Express (PCIe) specification allows for hot-swapping of PCIe devices. Since ExpressCard is simply PCIe and USB with different connectors, it would follow that PCIe to ExpressCard adapters should inherit such behavior when installed in computers with PCIe slots.

Detailed explanation-4: -Hot-plugging a device means the device is added or removed without shutting down the operating system or powering off the system. When you hot-plug a USB device, the device is immediately seen in the system’s device hierarchy, as displayed in the prtconf command output.
