Study Notes

Boundaries and Components

Boundaries define the system's space, separating it from the external universe, like a protective covering for a cellular phone.
Components are the parts that interact to fulfill specific functions; for example, a cellular phone comprises a circuit board, battery, connector, and antenna.
Inputs for systems include energy, matter, and information, while outputs result from processing those inputs, like radio signals converting into sound vibrations.

Inputs and Outputs

The process of converting inputs to outputs is essential; a radio signal (input) turns into sound (output).
Comparing systems, inputs and outputs of humans and robots can differ significantly in terms of matter and energy.

Open and Closed Systems

Open systems allow unrestricted flow of inputs and outputs, while closed systems have some limitations on their flow.
Isolated systems contain all inputs and outputs within themselves, minimizing external interactions.
Analyzing whether the human body or robots represent open, closed, or isolated systems brings insight into their interaction with the environment.

Controls

Controls within a system manage and monitor inputs and outputs, ensuring proper functionality.
Interactions with nonliving systems can affect the living systems; for example, cool air entering a warm space impacts human body temperature responses.
Feedback loops are crucial for systems; output from one step of a cycle influences a previous step, creating self-regulation.

System Models

Thermostats exemplify systems that manage temperature by responding to inputs (room temperature) and adjusting outputs (heating or cooling).
The complexity of a system can vary widely; for instance, a thermostat is relatively simple compared to a sophisticated chess-playing robot.

System Organization

Systems exist on a spectrum from small and simple to large and complex, showcasing diverse organizational structures in technology and biology.
