Similar to a wireless mouse, a wireless keyboard with touchpad works by plugging a receiver into your computer via a USB or PS/2 port. The keyboard sends a signal to the receiver. If you start to notice slower performance then usual, make sure that nothing is blocking the receiver and that the batteries in the keyboard are charged.
