Why OSI layers having 7 layers instead of one layer...

Answer / jitemdera ( cisco systems,us)

why we need OSI Layer

When the computer system come in in world every manufacture
uses there own model to process the data

in this case the computer of one Vendor can not communicate
with another Vendor

So to make it Standard we use OSI Model

Why the OSI model have 7 layer not One this is Bullshit
Question and i guess interviewer want to show hie knowledge

There are several reason let guess if we have only one
layer capable of holding all process of All seven layer

So what algo they will use
is it FIFO or what then think about CPU utilization for a
system ( You have change yours RAM and Processors in each
second)

This is Bullshit question and you have to replay in tcp we
have 5 layer only right

Every layer have there own function and while processing the
data every layer tags there signature on the data and the
process to next layer

as per example if in a bus a driver will do the duty of
Driver ,Ticket checker the Bus will delay like any thing

So is a Bullshit question ...
