Communication Technologies As a class, define Communication Technology? Use as many examples as possible.

Communication Technology Definition: all technologies used for the manipulation and communication of information. Transfer of messages (information) among people and/or machines through the use of technology. Brainstorm: what are some examples of communication technology?

Communication Technology - Mediums Communication Technology encompasses which media types/forms? Written note Instant Messaging (IM) Mobile Phone/Telephone Computer/Email TV/Video Radio Fax Camera Painting

Forms of Communication Biological Communication – communication that takes place without the use of technology. Ex. Speaking, facial expressions, and hand signals. Graphical Communication – visually sent messages including pictures and text. Ex. Magazines, newspapers, messages on clothing, billboards, road signs, computer images, etc.

Forms of Communication 2 Wave Communication – forms of communication that move through air, water, or outer space. Sound waves – vibrations traveling through air, water or other medium that can be perceived by the human ear. Electromagnetic Carrier Waves – radio and TV programs are converted into electrical signals. Signals are carried by electromagnetic carrier waves. Audio converted back to sound waves so we can hear. Light Waves – fiber optic cables transmit signals using light. When you take a picture, light waves from your subject bring the image to your eyes and the camera lens. Telecommunication – communication over a long distance. Satellites are used to carry the messages.

Section Assessment Are smoke signals a form of telecommunication? Humans have built in sound receivers. What are they and how do they work?

Modes of Communication People to People People to Machines Setting up a PVR/TiVo to record a TV program Computer programmers writing programs Using a keyboard/controller while playing a video game Machines to People A whistling teapot Alarm system Carbon monoxide/smoke detector Machine to Machine Your computer to your printer

Section Assessment Can you think of other examples of machines communicating with people? List 10. Explain how a baby who cannot talk communicates. What mode of communication is used: A computer program tells a robot how to paint a car. A computer spell-checker finds errors in a report. A friend passes a note.

Impacts of Communication Technology You will be assigned one of the following questions. In groups, brainstorm as many responses as possible and summarize your findings on chart paper. How has communication technology affected the world? What are some ways that communication technology affects politics? How might communication systems help people of different cultures get along with each other? How important is communication technology to you? How has communication technology affected the world economy? How has the environment changed due to communication technology?
