  1. OSI MODEL- It is a generic,protocol independent standard, acting as a communication gateway between network and end user.It follows vertical approach. OSI is a reference model around which the networks are built. Generally it is used as a guidance tool.OSI model has a problem of fitting the protocols into the model.Protocols are hidden in OSI model and are easily replaced as the technology changes.It has 7 layers.

    TCP/IP MODEL:TCP/IP model is based on standard protocols around which the Internet has developed. It is a communication protocol, which allows connection of hosts over a network.Follows horizontal approach.TCP/IP model is, in a way implementation of the OSI model.TCP/IP model does not fit any protocol. In TCP/IP, services, interfaces and protocols are not clearly separated. It is also protocol dependent.It has 4 layers.

  2. OSI Model:- It stands for Open system Interconnection Model. This model have 7 layers which provide a defined way of data transfer between the devices in a network. It is also used to open communicate with a system in a network without changing in a hardware and software. It is a Generic model and is protocol independent standard. The protocols of OSI Model can be easily replaced.It follows vertical Approach.

    TCP/IP Model: TCP stands for Transmission Control Protocol and IP stands for Internet Protocol. This model have 4 layers and is based on the standard protocols developed by the internet. It is a communication protocol which allows connection of host over a network. Protocols of TCP/IP cannot be easily replaced. It follows horizontal approach.

  3. TCP/IP is a communication protocol that allows for connections of hosts to the internet. OSI, on the other hand, is a communication gateway between the network and the end users. TCP/IP refers to Transmission Control Protocol used in and by the applications on the internet. OSI, on the other hand, refers to Open Systems Interconnection, a communication gateway developed by the International Organization for Standardization (ISO).here are four levels or layers upon which TCP is developed. These layers include the Link Layer, the Internet Layer, Application Layer and the Transport Layer. The OSI gateway, on the other hand, is developed upon a seven-layer model. The seven layers include Physical Layer, DataLink Layer, Network Layer, Transport Layer, Session Layer, Presentation Layer and, last but not least, Application Layer.When it comes to the communications, TCP/IP supports only connectionless communication emanating from the network layer. OSI, on the other hand, seems to do quite well, supporting both connectionless and connection-oriented communication within the network layer. Last but not least is the protocol dependency of the two. TCP/IP is a protocol dependent model, whereas OSI is a protocol independent standard.

  4. OSI Vs TCP/IP:
    1.OSI is a generic, protocol independent standard, acting as a communication gateway between the network and end user. TCP/IP model is based on standard protocols around which the Internet has developed. It is a communication protocol, which allows connection of hosts over a network.
    2. OSI model has a separate Presentation layer and Session layer. TCP/IP does not have a separate Presentation layer or Session layer.
    3. OSI is a reference model around which the networks are built. Generally it is used as a guidance tool. TCP/IP model is, in a way implementation of the OSI model.
    4. OSI model has a problem of fitting the protocols into the model. TCP/IP model does not fit any protocol.
    5. Protocols are hidden in OSI model and are easily replaced as the technology changes. In TCP/IP replacing protocol is not easy.
    6. OSI model has 7 layers. TCP/IP model has 4 layers.

  6. OSI MODEL IS 7 LAYER AND PROTOCOLS ARE HIDDEN IN OSI MODEL OSI MODEL CAN BE REPLACED
    OSI MODEL IS OTHER HAND 7 LAYER IS APPLICATION ,SESSION, PRESATATION,NETWORK,DATA LINK,PHYSICAL,TRANSPORT.

    TCP/IP MODEL IS 4 LAYER IS APPLICATION, PRESAENTION ,SESSION ARE SEPARATE. AND
    TCP/IP INTERFACE ,SERVICE,.TCP/IP MODEL DOES NOT FIT ANY PROTOCOL.
