Also read-
different types of protocols and different uses of protocol.

OSI
|
TCP/IP
|
OSI stands for open system interconnection because it allows any two different systems to communicate regardless of their architecture
|
TP/IP standard protocols / Internet protocols.
|
It has seven layer
|
It has four layer
|
In OSI model the transport layer guarantee the delivery of packets.
|
In TCP/IP models the transport layer dose not guarantee delivery of packets still the TCP/IP model is more reliable.
|
Follows vertical approach
|
Follows horizontal approach.
|
OSI model has separate presentation layer and session layer.
|
TCP/IP dose not have a separate presentation layer or session layer.
|
In OSI model transport layer is connection oriented.
|
Transport layer is both connection oriented and connection oriented less.
|
Network layer is both connection oriented and connection less.
|
Network layer is connection less.
|
OSI model has a problem of fitting the protocols into the models.
|
TCP/IP model dose not fit any protocol.
|
It is developed by ISO ( International standard organization )
|
Developed by DOD ( department defence )
