Question

How do the layers of the tcp/ip protocol suite correlate to the layers of the osi model?

Answer 1

Answer:

sorry mate ........... don't know answer

Answer 2

Answer:

The first three layers of the OSI model, namely the application, session, and presentation layers, correspond to the TCP/IP model's application layer. The TCP transport layer and the OSI model's transport layer correspond exactly. The network layer of the OSI model directly corresponds to the internet layer of the TCP/IP model.

Explanation:

The third and second layers of the OSI model are more likely to be network layers($3$. The Network Interface layer (layer $1$) of the TCP/IP model combines the operations of the OSI Data Link ($2$nd layer) and Physical ($1$st layer) layers.

• The transport layer in the OSI model is connection-oriented only. The TCP/IP model includes a layer that is both connection-oriented and connectionless.

• The data link layer and physical layer are distinct layers in the OSI model. The host-to-network layer in TCP combines the physical and data link layers into a single layer.

• The physical and data link layer functions are combined into one layer by the link layer. This includes frame synchronization and error detection, LLC and MAC sublayer operations, as well as frame physical network operations like modulation, line coding, and bit synchronization. The OSI model wasn't created until after the TCPIIP protocol suite. As a result, the layers in the OSI model and the TCP/IP protocol suite do not exactly correspond. Host-to-network, internet, transport, and application were the original four layers assigned to the TCP/IP protocol suite.

• The host-to-network layer, however, can be compared to the union of the physical and data link layers when TCP/IP is compared to the OSI model. The application layer roughly performs the functions of the session, presentation, and application layers, with the transport layer in TCP/IP handling some of the session layer's responsibilities. The internet layer is equivalent to the network layer.
• The five layers of the TCP/IP protocol suite are assumed to be physical, data link, network, transport, and application in this book. According to the first four layers of the OSI model, the first four layers provide physical standards, network interfaces, internetworking, and transport services.
