Assume you have a usb mouse, usb keyboard, and usb printer to connect to a computer, but you have only two usb ports. explain one solution to this problem that does not involve buying a new mouse, keyboard, or printer.

I guess the solution to that problem is that you should expand your USB ports, in order for you to do that is the best solution is you should buy a USB hub so that the number of USB ports will expand, and then plug your USB hub to one of your computer's USB port. After plugging the USB hub, you can now plug your USB  mouse, USB keyboard and USB printer to the ports of your USB hub.
