The internal description of a system refers to its inner workings and components, while the external description focuses on how the system interacts with its environment.
Having both internal and external descriptions allows for a comprehensive understanding of the system, including its functionality and how it is affected by external factors.
Internal descriptions are typically developed through analysis and modeling of the system's components and processes. External descriptions are often created through observation and data collection of the system's interactions with its environment.
Yes, as a system evolves and adapts to new environments or requirements, both its internal and external descriptions may change. It is important to regularly update and review these descriptions to ensure accuracy.
Yes, there are various tools and techniques such as modeling languages, data collection methods, and simulation software that can be used to develop internal and external descriptions of a system.
