What is system and subsystem?

Ans: System:

A system is an entity that exists to carry out some purposes. A system is composed of humans, machine and others things that work together to accomplish some goal which these same components could not produce independently. A system receives inputs from the environment and makes outputs to the environment.

Subsystem:

Subsystem is a part of a system. Each subsystem carries out part of the system function.

Human machine system:

Human machine system is a combination of one or more human beings and one or more physical components interacting to bring about for given input, some desired outputs. A human machine system can be a person with a hoe, a hammer or a hair curler.
