Post OSI model
This is what i am doing in school, is the OSI model

http://compnetworking.about.com/od/basi ... osimod.htm

There are 7 layers of a network

7 : application layer
6: Presention layer
5: Sessions layer
4: Transport layer
3:Network layer
2:Data link layer
1:physical layer

Each is Rather complicated

7 : application layer

This layer is what you see, Firefox, Windows xp, Programs that you can use.
6: Presention layer

Things that you can view, ASCII,
5: Sessions layer

Like cookies on firefox, Theres Sessions in networking, NetBios (windows net name )
4: Transport layer

This layer is how things are transferd, TCP , UDP http://en.wikipedia.org/wiki/NetBEUI
3:Network layer
ICMP, IP , IPX (router)

2:Data link layer
Ethernet and IEEE 802.11 (wireless) uses packages

1:physical layer

This is the easyest to expain, these are things you can see, touch

Nic's
Cables
Rotuers/Hubs
The types of the 802.11 (b/g/a/n)



Now if you go around and look, And if you can find more examples and details. I would really like that.
