a layered approach...

application - a written or spoken request...
presentation - how am i looking today...
session - quality time with your shrink
transport - a car, a train, etc...
network - a netlike combination of veins, filaments, etc...
datalink - the missing link; often...
physical - a song by olivia newton john

i needed to get layered...

it took a while to understand the osi model, to truly understand it and how it becomes essential to troubleshooting networks... i began to like theory; the biter got bitten...

encapsulation:

how i get my request prettied up for the shrink and into the car to a bunch of veins in search of the missing link dancing to an olivia newton john song?
