The Systems Model and
Communication
Information and Communication systems
follow the systems model and require
inputs, processes, outputs, and feedback.
Inputs – determine the objective of the project
or the action
Process – how the objective is achieved or the
procedure used (includes materials, tools,
supplies, etc.)

The Systems Model and
Communication
Information and Communication systems
follow the systems model and require
inputs, processes, outputs, and feedback.
Output – the results of the objective
Feedback – confirmation that the objective
was achieved; how the objective could be
improved

The Systems Model and
Communication
Example: Sending a text message
Input: the desire to send a text message
Process: entering the information using a mobile phone
Output: the message is displayed
Feedback: confirmation of the message

Information and
Communication
Information and communication systems can
be further broken down into the:
Source – the person or machine originating the
communication
Encoder – the device that translates the
communication into a format for transmission
Transmitter – the device that sends the message
Receiver – the device that collects
the message

Information and
Communication
Information and communication systems can
be further broken down into the:
Decoder – the device that translates the
communication into an acceptable format
Storage – the device that stores the
communication
Retrieval – the device that retrieves the
communication on command
Destination – the person or machine
who is the audience

Information and
Communication
Example: Sending an email
Source:
the person
typing
the email
Destination:
the person to
whom the email
is addressed
Encoder:
the keyboard,
the CPU, the
email program
used to create
an email
Transmitter:
modem or
wireless
modem, the
email program
that sends the
email
Receiver:
router, the
email program
that receives
the email
Retrieval:
the software
application that
displays the
email
Storage:
hard drive,
server, the
email program
inbox
Decoder:
the CPU, the
email program
that displays
the email

Non-Verbal
Communication
Nonverbal communication is the process of
communicating without using words, generally
using visual cues between people.
Nonverbal communication is used for
interpersonal communication or communication
between people
Kinesics – the study of communication
through gesture, posture, and movement
Haptics – the study of
communication through touching
