Describe about the Environmental model
It indicates environment in which system exists. Any small or big system is a sub-system of a larger system. For illustration, if software is developed for a college, then college would be part of University. If it's developed for University, University will be part of national educational system.

Environment of a college system is demonstrated in figure below.
