How does TCP and IP address works on networking?

Answer 1

TCP/IP is composed of layers, wherein each layer is responsible for performing certain operations on the data it receives and passing it to the higher layers. Each layer deals with certain issues related to the transmission of data and renders certain services to its higher layers.

The TCP/IP model consists of the link layer, the internet layer, the transport layer and the application layer. Each layer consists of a set of protocols that function on the level of that layer. The link layer protocols are responsible for connecting the nodes in a network. The Internet layer consists of protocols, specifications and methods that are used to transport data packets across the network. The transport layer protocols deal with the transmission of data packets between source and destination network hosts. The application layer, the topmost layer in TCP/IP, directly interacts with application services. Thus, we see that TCP/IP functions at all the levels of communication between the components of a network. It is truly, the heart of network communication.

Answer 2

The TCP/IP model describes the functionality of the protocols that make up the TCP/IP protocol suite. These protocols, which are implemented on both the sending and receiving hosts, interact to provide end-to-end delivery of applications over a network.

A complete communication process includes these steps:

1) Creation of Data

2) Segmentation and encapsulation of Data

3) Generation of the Data

4) Transportation of the Data

5) Reception of the Data

6) Decapsulation and reassembly of the Data

7) Passing this Data to the destination
