What can be achieved using the OSI model?
In: Engineering
A metaphor for the OSI framework is to imagine you’re writing an essay
First layer – physical – using a blue ink pen and white paper
Second layer – characters will be written left to right then top to bottom using a 1/4 inch line spacing and 1 inch margins
Third layer – the words will be written using the Roman alphabet, in cursive style
Fourth layer – the language used for the words will be English spelling
Fifth layer – the format will be using sentences and paragraphs using English grammar and syntax
Sixth layer – the essay structure will have a title, introduction, main content and conclusion
Each layer except for the first is an abstraction.
