Discussion :: TCP/IP - TCP/IP (Q.No.2)


What layer in the TCP/IP stack is equivalent to the Transport layer of the OSI model?

[A]. Application
[B]. Host-to-Host
[C]. Internet
[D]. Network Access

Answer: Option B


The four layers of the TCP/IP stack (also called the DoD model) are Application/Process, Host-to-Host, Internet, and Network Access. The Host-to-Host layer is equivalent to the Transport layer of the OSI model.

Its wrong there is only host to network which is for physical and data link layer. It (TCP/IP) has its own transport layer as do OSI.

Host to host is present in 3 layer model not 4 layer.

The Host-to-Host layer is the lowest layer of the TCP/IP reference model. It combines the link layer and the physical layer of the ISO/OSI model.

The TCP/IP model's transport or host-to-host layer corresponds to the fourth layer in the Open Systems Interconnection (OSI) model, also called the transport layer.

1. Network Access----------Physical and Data. (Host to Host).

2. Internet----------------Network.

3. Transport---------------Transport.

4. Application-------------Session, Presentation and Application.

TCP/IP Host-to-Host Layer is equal to Physical and Data Link Layer of OSI Model, Network Layer is same in both models.

It is incorrect.

Transport layer if TCP/IP model is equivalent to the transport layer of OSI model.

Pradeep said: (Dec 20, 2017)  
There are four layers in TCP/IP model.
* 1- Link
2- Internet
* 3- Transport
4- Application

* Sometimes Link layer is known as Network Access layer and Transport layer is known as a Host-to-Host layer.

That is correct! The transport layer of the TCP/IP model is also known as host-to-host.

OSI ------ tcp/ip
1. Application Layer+Presentation+Session - Application Layer.
2. Transport Layer - Transport Layer or Host to Host Layer.
3. Network Layer - Internet layer.
4. Physical+Data Link layer - Network Access Layer or Host to Network Layer.

The transport layer is process to process right?

Is Host to Host and Process to Process both are same? Anyone explain.
