One of the best ways to reduce the cords used on a computer or electronics system is to consider wireless devices that can talk to a home device without the use of a USB cable or cord to connect it. Sometimes a central hub is used to talk to each of the devices in a theater or computer system and this hub requires only one cord to connect it to the brain of the system. Other systems allow for a few devices, such as a keyboard and mouse for a keyboard, to be connected through a USB transmitter.
