Question

your company has just upgraded your laptop computer. after receiving your new computer, you plug your external usb 2.0 hard disk into your new usb 3.0 port. which of the following is the most accurate statement regarding how this device will function? the device will require an external power source. the device will be able to transfer at usb 3.0 speeds. the usb 2.0 device will not work in the usb 3.0 port. the device will work but only transfer at usb 2.0 speeds.

Explanation:

USB 3.0 ports are backward - compatible with USB 2.0 devices. This means that a USB 2.0 device can be plugged into a USB 3.0 port and will function. However, the data transfer speed of the device is limited by its own USB 2.0 specification, so it will transfer data at USB 2.0 speeds rather than USB 3.0 speeds. Also, a typical USB 2.0 external hard disk does not require an external power source just because it is plugged into a USB 3.0 port, and it will work in the USB 3.0 port.

Answer:

D. The device will work but only transfer at USB 2.0 speeds.
