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 usb 2.0 device will not work in the usb 3.0 port.
the device will work, but will only transfer at usb 2.0 speeds.
the device will require an external power source.
the device will be able to transfer at usb 3.0 speeds.

Explanation:

USB ports are backward - compatible. A USB 2.0 device plugged into a USB 3.0 port will work, but it will transfer data at its own maximum speed (USB 2.0 speed in this case), not at USB 3.0 speeds. Also, most external USB 2.0 flash drives draw power from the USB port and do not require an internal power source.

Answer:

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