TYPES OF Communication Communication Systems

Types of Communication Biological Communication that takes place without technology Examples: Verbal Non-verbal (body language) NO TECHNOLOGY

Biological Types of Communication Advantages Instantaneous Personal Immediate feedback (response to action) Disadvantages Limited by time/space Easily lost Distortion of information (rumors)

Biological Examples

Types of Communication Graphic Uses stationary pictures and symbols Examples: Book Poster Symbols/Signs Art NO TECHNOLOGY

Graphic Types of Communication Advantages Easily stored Portable Disadvantages Limited by space (Ex: book) Less personal (Letter) Perceptions may differ

Graphic Examples

Types of Communication Wave Uses an energy source to move through air, water, outer space, or solids Examples: Cell phones Computers TV Radio Satellite YES TECHNOLOGY

Wave Types of Communication Advantages Quicker Cheaper Vast Information Disadvantages Limited by technology Not universal Storage – not as easy

Wave Examples

Types of Communication Systems People-to-People Is when one person is doing the input in order for another person to receive the output Examples: Radio and television Audio and video recordings Web sites Communications in space Printing Photographs Telecommunications

Types of Communication Systems People-to-Machine Is when one person is doing the input in order for a machine to process the output Examples: Computer programmers Video games

Types of Communication Systems Machine-to-People Is when a machine is doing the input in order for a person to receive the output Examples: Telemetry – is using pictures and satellite readings to send back information from unreachable places Car alarms Traffic lights

Types of Communication Systems Machine-to-Machine Is when one machine is doing the input in order for another machine to process and receive the output Examples: CAD Assembly lines Internet (server to server)
