Abstraction allows us to proceed with the development work
without been held up in low-level implementation details
(yet to be discovered)
Eg:- Develop software that will perform 2-D drafting (CAD)
* Software will include a computer graphic interface which
will enable the draft-person to see drawing and to
communicate with it via a mouse. All line and curve drawing,
geometric computations. Will be perform by the CAD software.
Drawing will be stored in a drawing file.
(Here it only concentrate on a task at some level of
generalization (High level details) without regard to low
level details)
