Answer / s.m.feroz ahmed

Hi,
In OSI Layer there are 7 layers on Source Side and 7 layers
on Destination Side and this concept is mapped in VIceVersa
direction.On Source side Application layer is always serial
no 1 and while on destination side it is converted to
serial no 7 as to travel from Source to destination the
application layer has to pass overcome all the remaining 6
layers and reach destination layer with serial no 7.

I hope you got the concept of OSI Layer.
