OSI vs TCP/IP

 In this article, we gonna see the difference between OSI Model and TCP/IP Model. Which is better ISO or TCP/IP??  How they are similar to each other??

OSI Comparison with TCP / IP Reference Model:

    The OSI (Open System Interconnection) model introduced by the ISO (International

General Organization). Currently the OSI (Open System Interconnection) model is just a model

reference model. That is, there is no real implementation of the OSI

Model on any of the latest network infrastructure or Operating Systems. OSI (Open

System Interconnection model) is currently used only as a reference model

teaching computer network concepts and understanding how computer networks work

.

    The TCP / IP (Transmission Control Protocol Internet Protocol) root is in the US

Department of Defense (DoD). Original TCP / IP (Transmission Control Protocol / Internet

Protocol Model) had only four layers, and later the revised model appeared five

layers. The TCP / IP protocol suite and thus the TCP / IP model received wider acceptance than the OSI

model, because the world's largest network started operating using the TCP / IP protocol

suite.

OSI vs TCP Comparison

Major Differences between OSI and TCP/IP:

1. OSI: OSI is a generic, independent protocol standard, acting as a communication gateway between network and end-user.

• In the OSI model, it is in the transport layer that ensures packet delivery.
• It follows a straight path.
• The OSI model is different Presentation background and Session background.
• The transportation layer is communication Directed.
• Network Background is for both Communication Oriented and Slightly Connected.
• OSI is an all-around reference model built networks. Usually, it is used as a directional tool.
• The OSI model network layer provides both tend to reconnect offline service.
• OSI model has trouble installing protocols in the model.
•  Protocols are hidden in the OSI model and are easily replaced as technological changes.
• The OSI model describes services, interfaces, and agreements clearly to make a clear distinction between them. It was independent.
• It has 7 layers.

2. TCP/IP: The TCP / IP model is based on standard protocols where the Internet is built. It is a communication protocol, which allows communication of web hosts.

• In the TCP / IP model, the transport layer does not ensure packet delivery. However TCP / IP model is more reliable.
• It follows a horizontal path.
• TCP / IP does not have a separate Presentation background or Session background.
• The transport layer is both connection-oriented and connectionless.
• Network Background is Small Connection.
• The TCP / IP model is a user-friendly OSI model.
• Network Layer for TCP / IP model provides offline service.
• The TCP / IP model does not match any protocol.
• For TCP / IP replacing a protocol is not easy.
• In TCP / IP, resources, meeting places, and protocols are not clearly separated. It is also protocol-dependent.
• It has 4 layers

Similarities Between TCP/IP and OSI:

1. They both have layered architecture models.

2. Their layer provides similar functionalities.

3. They both have a protocol stack.

4. They both are known as a reference models.

Which is Better TCP/IP or OSI:

    Whenever we use the network and try to connect and communicate with different devices via the network. We use the OSI or TCP / IP reference model. But the question always arises in our mind, which is the best model for specification, implementation, connection, communication, etc.

As we know each coin has two faces. Similarly, we cannot say that one model is the best and the other is the worst. They both have some advantages and disadvantages as well. One model can work well in another and worse in another. So in this blog, we will take some of the key points of network and communication, and explore which model is best for which situation.

As we have already talked about the advantages and disadvantages of the TCP/IP and OSI Model.

Therefore, we can conclude that both models have their advantages and disadvantages. If someone focuses on proper writing, specification, and module editing, they should prefer the OSI model over the TCP / IP model. But if someone is more focused on network usage, reliability, and security, they should prefer the TCP / IP model over the OSI model.
