[comp.mail.misc] Definition of a network

j15@nikhefh.nikhef.nl (Marc Peeters) (09/26/89)

As a part of my practical work, I'm investigating how bounced mail is handled
on different sites.
For the paper that I'm writing, I need a definition of a "computer network".
 
We all know what a network is (don't we?), but giving a good definition
turns out to be more difficult.

Personally, i make a seperation between the first 3 layers of the OSI model
(which I call the fysical network) and the upper layers (which I call
the logical network). 
 
My question to you all is: 
What do *YOU* think is a good definition of a computer network in general
and what do you think is a good definition of both a fysical and a
logical network?

If you send me your answers (thank you already, BTW) by e-mail, than
I will make a summary of them to the net.
