Systems
§A
system is a number of parts that work together to accomplish a goal.
There are two different types of systems, natural and devised. Natural
systems are used to describe the physical world. Devised systems are
used to describe systems created by people. These systems are designed
to serve some purpose. One of the best examples of a devised system is
the Roman aqueducts. This complex system of pipes supplied Rome with
millions of gallons of water each day.
System Model
§The
purpose of a system is to reach a desired output. The inputs are what
the system requires to achieve the output. All of the actions occur in
the process. If the system contains a feedback loop, then it’s
considered a control system.
§A
simple communication model consists of a sender, channel, message,
receiver, and feedback. The basic systems model needs input, process,
output, and purpose.
Resources for Communication
§Resources
are required in order to send a message. The most important resources in
communication are:
-People
-Information
-Materials
-Capital
-Finances
Without these resources, it would be impossible to send a message.
