Is an example of an input device?
A mouse is an input device.Very good. This is a good example of an input device. An imput device is any signal that is introduced to the receiver. The mouse is a plug-in physical signal. But there are wireless signals as well. You can have a wireless mouse. It has a pre-set wireless signal and when the computer recognizes it, it works.The receiver is an output device. When you add an imput device to a radiio, or an amplifier or a channel receiver, you are adding a signal to the receiver. The receiver recogniizes the signal and responds accordingly. If it does not recognize the signal, nothing happens. The receiver cannot process it. When you turn the dial on your radio or tv, you are changing the signal electronically. So it is true when you add cable to your tv. this gives you imput signals. Your tuner reacts accordingly. Change the imput, change the channel.
