Wired and Wireless Communication.

Wired Communication
Wired communications is a broad term that is used to describe any type of communication process that relies on the direct use of cables and wiring to transmit audio and visual data. A classic example of wired communications is the traditional home telephone that is connected to the local telephone switch via wires that are ran from the home to the switch. While wireless communication solutions have become more common in recent years, the use of wired services remains common and is not likely to disappear in the near future.

Wireless communication
In telecommunications, wireless communication may be used to transfer information over short distances (a few meters as in television remote control) or long distances (thousands or millions of kilometers for radio communications). The term is often shortened to "wireless". It encompasses various types of fixed, mobile, and portable two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of wireless technology include GPS units, garage door openers and or garage doors, wireless computer mice, keyboards and headsets, satellite television and cordless telephones.
