There are lots of different ways that electronic devices can connect to one another. For example:

When you use computers, entertainment systems or telephones, the various pieces and parts of the systems make up a community of electronic devices. These devices communicate with each other using a variety of wires, cables, radio signals and infrared light beams, and an even greater variety of connectors, plugs and protocols.

The art of connecting things is becoming more and more complex every day. We sometimes feel as if we need a Ph.D. in electrical engineering just to set up the electronics in our homes! In this edition of HowStuffWorks, we will look at a completely different way to form the connections, called Bluetooth. Bluetooth is wireless and automatic, and has a number of interesting features that can simplify our daily lives.
