Indicates whether the product can be connected or removed while it is powered on without requiring a shutdown or reboot. A value of "Yes" means the device supports hot‑plugging, allowing components such as drives, peripherals or expansion cards to be added or removed safely during operation; "No" indicates that the device must be powered down before any hardware changes.

The highest theoretical speed at which a device can send or receive data, expressed in bits per second (bps) or its multiples such as kbps, mbps, gbps, etc. This value represents the upper bound of throughput under optimal conditions and is useful for comparing performance across devices and interfaces.

The greatest linear distance over which a device can reliably transmit signals or data, expressed in units such as meters, feet, or inches. It indicates the maximum reach of cables, wireless links, or other transmission media under typical operating conditions.
