Why each option
USB technology allows for hot plugging of devices, meaning they can be connected or disconnected while the computer is running, and can support up to 127 peripheral devices through the use of hubs.
USB supports hot plugging, enabling users to connect and disconnect devices without needing to power down or restart the computer, enhancing user convenience.
Through the use of USB hubs, a single USB host controller can manage a tiered star topology that theoretically supports up to 127 peripheral devices.
The limit of 16 peripheral devices is incorrect; USB's architecture with hubs allows for significantly more, up to 127.
USB is designed for and fully supports Plug and Play (PnP) installation, which automatically configures and installs drivers for connected devices.
