What is TCP IP Model

Have you ever had too many computers? networking will have information. The topic of our blog is TCP/IP Model, What is TCP/IP? How many layers does it have? If you want to know what is TCP / IP Model in Hindi, then you should read this blog till the last and if you understand then definitely share it with your friends, then let’s start and know what is TCP IP model in Hindi. Is?

What is the TCP/IP Model?

The full name of TCP/IP is Transmission Control Protocol/Internet Protocol. It is a set of rules that decide how the Internet works. TCP/IP is used in real environment, TCP/IP is a protocol of world-wide-web (www) which we call Internet. All networks and protocols work on TCP/IP model. This model provides end-to-end communication. It was developed at the US Department of Defense (DOD) between the 1970s and 1980s. The main purpose of the TCP/IP model is to provide communication over a long distance, that is, we can also communicate with the network located at a long distance through this model.

This model helps us to create virtual networks when many computer networks are interconnected. TCP/IP Model is a connection oriented and reliable model protocol. It completely verifies the connection before transferring the data whether the connection is established with the receiver device or not. The TCP/IP model uses a client-server communication model in which one computer (user) requests a service, in response to which another computer (server) on the network provides service.

How many layers does the TCP/IP model have?

The TCP/IP model consists of the following 4 layers, which are given below-

  1. network layer
  2. internet layer
  3. transport layer
  4. application layer

application layer

It is the highest layer of the TCP/IP model. This layer provides communication to the users. The application layer sends data to the transport layer and receives data from it. The job of the application layer is to handle the high level protocols. This layer allows the user to interact directly with the application.

The following are the protocols used in the application layer-

  1. HTTP (Hypertext Transfer Protocol) and HTTPS (HTTP-Secure)
  2. SNMP (Simple Network Management Protocol)
  3. SMTP (Simple Mail Transfer Protocol)
  4. DNS (Domain Name System)

transport layer

The transport layer lies between the application layer and the Internet layer. This layer is responsible for data transmission, flow control, correction and reliability. When our data comes from the application layer to the transport layer, it gets divided in the form of data segments and now the data is sent in the form of these segments. The main two protocols work in this layer-

  1. Transmission Control Protocol (TCP)
  2. User Data Village Protocol (UDP)

internet layer

The Internet layer is located between the transport layer and the application layer, this layer provides connectionless communication in the network. In this, the data is in the form of datagrams, these datagrams keep the IP address of the source and destination so that the data can be easily received and sent, this layer has three important functions:

  • Inter-networking: When two or more networks are interconnected, it is called inter-networking, controlling this is the main function of the Internet layer.
  • Logical Addressing: In order to communicate between the host and the receiver, it assigns an IP address to the host.
  • Routing: The function of routing is to find the best path to transfer data from source to destination. Routing provides the shortest and best route for data transfer.

The following protocols are used in this layer-

  1. IP Protocol (Internet Protocol)
  2. ARP Protocol (Address Resolution Protocol)
  3. ICMP (Internet Control Message Protocol)

network layer

It is the lowest layer of the TCP IP model. The layer is a combination of the data link layer and the physical layer defined in the query model. The network layer is responsible for the transfer of data between 2 devices in the same network. This network This layer is used in host-to-host communication. The function of this layer is to encapsulate IP datagrams transmitted by the network into frames and map IP addresses to physical addresses. The network layer has two sub-layers-

  • MAC Sub-layer: This layer deals with MAC address.
  • Physical sub-layer: This layer works in the physical transmission medium.

What is TCP/IP protocol?

(TCP IP Model in Hindi) TCP / IP model generally uses two protocols, these two protocols join together to form the TCP-IP model.

1.TCP Protocol-Transmission control Protocol
2. IP Protocol- Internet Protocol

1. TCP Protocol

In this connection is first established between the sender and the receiver which is finally released. TCP protocol is a connection oriented and reliable transport protocol i.e. it verifies the connection before data transfer, only after which the data is transferred. it happens.

2. IP Protocol

The set of rules for transferring data from one computer to another on the Internet and other networks is called Internet Protocol. The data that is transferred over the Internet is divided into small pieces, which are called packets. IP information is attached to each packet and this information helps the router to forward the packet to the destination.

How does the TCP/IP model work?

The TCP/IP protocol protects the data in the Internet and makes it reach its destination. TCP / IP divides the entire data into small data packets and sends it to the Internet. Now IP (Internet Protocol) transmits this data to its destination point, which establishes communication between the Internet and the network. In both these protocols, communication is not possible without the Internet.

The implementation of TCP/IP is the same for all computer hardware and operating systems. All types of computer hardware networks can communicate with each other via TCP/IP. TCP/IP protocol is a connection oriented and reliable protocol. It completely verifies the connection before transferring the data whether the connection is established with the receiver device or not. The TCP/IP model uses a client-server communication model in which one computer (user) makes requests, in response to which another computer (server) on the network provides service. We use TCP / IP protocol in many types of servicing like- HTTP, HTTPS, TELNET, FTP etc.

TCP/IP Services

To know what is TCP/IP let us know about its services, which are as follows:

  1. stream delivery service
  2. Sending and receiving buffers
  3. full duplex service
  4. connection oriented
  5. reliable service

What are the characteristics of TCP/IP model?

  1. This model can be made quite large.
  2. This model works independently.
  3. The TCP/IP model supports many routing protocols.
  4. The client server structure can be built in this model.
  5. The TCP/IP model is used to create a connection between two computers.
  6. This model helps us to establish connections in different types of computers.
  7. It is an open protocol suite, meaning it does not belong to any company, so it can be used by any person or company.

Disadvantages of TCP/IP Model

There are also some disadvantages of TCP ip model in Hindi, which are as follows:

  1. It is a complex model so it is difficult to manage and set up.
  2. The transport layer of this model does not guarantee the delivery of packets.
  3. This model cannot be used in any other application.
  4. There is no difference between the service and protocol of the optimized TCP/IP model.

What are the differences between the TCP/IP model and the OSI model?

After knowing what is tcp/ip, what are the main differences between TCP/IP model and OSI model, they are as follows-

  1. The OSI model is a 7 layer model while the TCP IP model is a 4 layer model.
  2. OSI Model was developed by the International Organization for Standardization in 1980 while the TCP/IP model was created by the United States Department of Defense in 1970.
  3. The OSI model was designed to understand the working of the network whereas TCP/IP was designed to solve a specific problem.
  4. The OSI model follows a vertical approach while the TCP/IP model follows a horizontal approach.
  5. In OSI model protocols are hidden which can be easily converted into technology whereas in TCP/IP model it is not easy to refresh protocols.
