Why do you think the tcp,ip (internet) model is more widely used than the osi model?

Reliable and Secure Connection: The OSI model does not have any special mechanism for providing a reliable and secure connection for data transmission. On the other hand, the TCP/IP model has a 3-way handshake mechanism for providing a reliable and secure connection link oner the network.

Beside above, why is TCP IP still widely used? TCP/IP is widely used primarily because it is standardized vs competing networking protocol suites such as IPX/SPX and Appletalk. The World Wide Web, the web, is another reason TCP/IP is so popular. HTTP is an application layer protocol designed within the framework of the Internet protocol suite.

You asked, what are the advantages of Internet Protocol TCP IP over OSI model?

  1. It is an industry–standard model that can be effectively deployed in practical networking problems.
  2. It is interoperable, i.e., it allows cross-platform communications among heterogeneous networks.
  3. It is an open protocol suite.
  4. It is a scalable, client-server architecture.

Moreover, why OSI model is not widely used? The disadvantages of the OSI model are It is purely a theoretical model that does not consider the availability of appropriate technology. This restricts its practical implementation. The launching timing of this model was inappropriate. When OSI appeared, the TCP/IP protocols were already implemented.

Correspondingly, which is more reliable OSI or TCP IP? In OSI model the transport layer guarantees the delivery of packets. 2. In TCP/IP model the transport layer does not guarantees delivery of packets. Still the TCP/IP model is more reliable.Today, it is the main protocol used in all Internet operations. TCP/IP also is a layered protocol but does not use all of the OSI layers, though the layers are equivalent in operation and function (Fig.

Why has the Internet model replaced the OSI model?

Why has the Internet model replaced the OSI model? The Internet model is simpler (effectively collapsing the top three layers of the OSI model into a single model) and easier to remember and understand.

What is the purpose of the OSI model?

The OSI Model (Open Systems Interconnection Model) is a conceptual framework used to describe the functions of a networking system. The OSI model characterizes computing functions into a universal set of rules and requirements in order to support interoperability between different products and software.

What is TCP IP model explain?

TCP/IP Reference Model is a four-layered suite of communication protocols. … TCP stands for Transmission Control Protocol and IP stands for Internet Protocol. The four layers in the TCP/IP protocol suite are − Host-to- Network Layer −It is the lowest layer that is concerned with the physical transmission of data.

What are the advantages of using a theoretical model to describe networking?

what are the advantages of using a theoretical model to describe networking ? * it give a common language and reference point for network professionals. * It divides networking task into logical layers that are easy to understand. what is the name Of layer 3 in the OSI model ?

Why the models are vitally important to networking?

Models provide a starting point for determining what must be done to enable communication or to figure out how systems using different protocols might connect to each other. They also help in troubleshooting problems.

What are the disadvantages of OSI model?

  1. It doesn’t define any particular protocol.
  2. It may find sometimes difficult to fit a new protocol in this model.
  3. The session layer is used for session management.
  4. There is some duplication of services at various layers.
  5. There is also interdependence among the layers.

How does the TCP IP model compare to the OSI model?

OSI model is generic, protocol independent, yet most protocols and systems adhere to it, while TCP/IP model is based on standard protocols which the Internet has developed. Another thing should be noted in OSI model is that not all layers are used in simpler applications.

What is the difference between TCP IP model vs OSI model?

OSI refers to Open Systems Interconnection whereas TCP/IP refers to Transmission Control Protocol. OSI follows a vertical approach whereas TCP/IP follows a horizontal approach. OSI model, the transport layer, is only connection-oriented whereas the TCP/IP model is both connection-oriented and connectionless.

What is the purpose of OSI model and TCP IP model?

The OSI reference model describes the functions of a telecommunication or networking system, while TCP/IP is a suite of communication protocols used to interconnect network devices on the internet. TCP/IP and OSI are the most broadly used networking models for communication.

Where is TCP IP in the OSI model?

The best known example of the Transport Layer is the Transmission Control Protocol (TCP), which is built on top of the Internet Protocol (IP), commonly known as TCP/IP. TCP and UDP port numbers work at Layer 4, while IP addresses work at Layer 3, the Network Layer.

What is the difference between OSI model and Internet model?

OSI makes a clear distinction between the model and implementation, while the Internet is more fuzzy. OSI is very general, whereas Internet is very specific. OSI is more flexible in that is it not tied to a specific protocol and is better able to adapt to changes in technology.
