Does anyone know in lament terms what the OSI is?

From research i gather its some sort of structure, in which network setups follow.

I've seen the 7 stages, but i've been asked how each network component will function with respect tot he ISO model.

I'm a bit stuck. I've not heard of it until about an hour ago, and i'm finding it all a bit hard to digest to answer the question.

If anyone could explain it or give me an example of a component paired to a level/stage then that would be more the great.

Cheers.

Some sort of homework?
 
In real laymens terms it is a 7 layer framework that is a reference mode.

About the only thing that I can think of that fits into the model is DecNet IV phase 5 (unless you did DEC VAX then don't worry if never heard of it)

As such networking components don't fit into the model.

So networking components don't even fit in to the layer?

Here's the question:

"Explain how each network component you select will function with respect to the 7-layer OSI/ISO model"

I was asked to design a network for a small buiness, equipment includes, servers, PCs, Switch, Router/modem, Firewall, internet.
 
Server: Layer 7 (Provides HTTP, FTP, PDC, Files)
PC: Layer 7 (Accesses HTTP etc)
Switch: Layer 2 as it just deals with physical addresses (MAC addresses)
Router: Layer 3 as it deals with logical addresses (IP addresses)
Firewall: Can go up to layer 7 depending on what filtering method.
Internet: The Internet itself is just routers connecting networks so Layer 3

That's useful, cheers mate. :)
 
No Problem, basically the main layers are those stated though.

Layer 1 - Cables
Layer 2 - Switches/Bridges
Layer 3 - Routers
Layer 4 - TCP/UDP Protocols
Layer 5/6 - Nothing special in these really
Layer 7 - HTTP, FTP, SMTP, SNMP Protocols n services.
