Networking

Hi all, sorry to start a new thread.
I am completely confused, one web page says one thing, another says the opposite.

Does TCP/IP exist in the OSI model(layer 4).
If not, then what are they both used for.
Ie, TCP -e-mail.

 

Tut tut... someone not listening in their networking class?

I can't remember, I can root out my networking notes if your really stuck though...

 

Something like that. Been about 5 years since I done it but my notes are less than useless

 

been years but:

tcp is layer 4 for transporting data between the model and IP is in the network layer (3) which deals with address and routing of traffic.

You mentioned email that uses both the transport layer and the application layer (7).i think

Again its been years and i must look over my notes as i am scheduled to do a ccna course soon as this is the basics

 

Thanks, it was TCP/ip and TCP that confused me.

Took me a while to realise TCP/ip is a model and TCP is a protocol
