The term "hot pluggable" refers to devices that can be added or removed from a system while it is powered on, without requiring a reboot or software restart. This capability is crucial in environments that require high availability and minimal downtime, such as servers and enterprise systems. Hot-pluggable devices include USB drives, hard drives in certain configurations, and various peripherals that support this functionality.
This characteristic allows for greater flexibility and efficiency. For example, in a server environment, an IT technician can replace a failed component without disconnecting the entire system, thus maintaining ongoing operations. This ability enhances uptime and minimizes disruption in workflows, which is especially important in mission-critical applications.
The other options refer to different types of connectivity and device management, such as cold pluggable, which involves the device requiring the system to be powered down for installation or removal. Understanding the distinction between these types is essential for effectively managing device installations in various computing environments.
