Advantages of TCP/IP Model.

 

  1. It ensures that all the devices visit the internet are recognizable since it issues a unique address to each one of them for identity purposes.
  2. Enhances scalability since its services are not disrupted during additional of a network.
  3. Organizations are able to inter-network among themselves by the help of this model.
  4. A secure connection can be set up between one computer and another.
  5. The model is open for use by anyone as long as the person is authorized since it is not entitled to a particular person

Disadvantages of TCP/IP Model.

  1. Its intended purpose as it was being developed was for wide area networks and hence it is not suitable for use by networks using local area network.
  2. TCP/IP Model does not give the exact difference between the physical layer which is the lowest layer and the data-link which follows the physical layer. The two layers have functions which are not similar to each other which the model does not well define.
  3. The model is more complex and complicated to understand how data is transmitted through a network from the source to the destination.
  4. The process involved in the replacement of a protocol is not easy using the TCP/IP Model.

DIFFERENCES BETWEEN OSI MODEL AND TCP/IP MODEL

  1. The OSI model was established by International Standard Organization (OSI) while the TCP/IP model was established by Advanced Research Project Agency Network ( ARPANET).
  2. The OSI model states a clear difference between services, protocols and interfaces while TCP/IP does not clearly state differences between services, protocols and interfaces.
  3. The OSI model consists of seven layers while the TCP/IP model consists of four layers.
  4. In the OSI model, the physical layer and data link layer are two separate layers while in TCP/IP model they are combined to form the Network layer.
  5. The approach used in OSI model is vertical while the approach used in TCP/IP is horizontal.
