OSI is known as the horizontal approach while TCP/IP is known as thevertical approach. There are seven different layers in the OSI model while the number of layers for TCP/IP modelare four. ... TCP/IP does not fit in any other model while OSI tries to fit in other models because it is a reference.

sorry mam but my confusion is about what is horizontal approach.

In the OSI model, there are no intermediate nodes between transport layer or above layers....hence these layers communicate directly with each other....hence horizontal approch
Thanks mam for this wonderful video. Can we get these notes as well plz??
Why TCP/IP is more reliable in comparison with OSI ?
