Cordless
Alternatively referred to as wireless, cordless is the ability to operate a device without any wires that may cause constricted movement. Cordless computer hardware devices commonly utilize such Infrared or Bluetooth. Cordless networks, more commonly known as a Wi-Fi network, utilize one of the IEEE 802.11 wireless standards for wireless communication.
Although cordless devices requires no wires, they do require some device to broadcast a signal; for example, a Bluetooth mouse may require a USB Bluetooth transceiver to send and receive signals from the mouse. In addition to this, all wireless hardware devices require batteries.
