"Hi, my name is Tom and I'm here with Best Buy and we're going to show you what a wireless keyboard is today. A wireless keyboard is a keyboard that does not need to be plugged directly into your either notebook computer or desktop computer in order to work. The way that the wireless keyboard works is that you have some sort of receiver, usually a USB receiver which sends a signal to the keyboard, allowing you to use it without being plugged directly in. Now, most wireless keyboards are going to be battery powered, so make sure that you do have batteries on hand, install those before using. So, that's what a wireless keyboard is.
