A wired network is one which is connected together by cables, typically coaxial or Ethernet cables (whether they be 10, 100 or 1000 base-T, parallel or serial, etc.) A wireless network is connected by some kind of wireless transmission, usually a wireless router projecting a certain radio frequency. It is important to note that a wired network can have wireless components, say a wireless computer participating or a wireless printer, while a wireless network can and almost always do have wired components, like a final physical throughput (cable, DSL/phone lines, â€Å"satellite† - which is effectively a â€Å"wired† network for this discussion, etc.) Light is used to encode information and send â€Å"bits† the same way a phone line can.
