There is a very obvious difference between a normal keyboard and a wireless keyboard. One uses infrared beams to transfer information to and from the computer and the other is plugged directly into the computer via a cable. When you type on your keyboard the information is sent to the computer via the infrared beam or signal to a receiver which is in the computer. There is one main advantage to using wireless keyboards. When you have a have a wireless keyboard it will eliminate the messy wires and you will be able to move around freely with it. When people opt for wireless keyboard they will also get wireless mice with them too since then they won’t have any wire restrictions at their desk. When you have a keyboard that is attached to the computer via a cord you may not be able to keep it in a place that is most comfortable for you. If you have a wireless keyboard on the other hand then this will not be the case korg keyboards. Different ones have different distance ranges from which they can operate so you have to check on this before you purchase a wireless keyboard but if you want convenience then you should opt for a wireless keyboard as they are more flexible.
