A. B. C. D. E.


The TCP/IP model is a four-layered model used for communication over the internet. It was developed prior to the OSI model and is widely used today. The four layers in the TCP/IP model are:

  1. Application layer
  2. Transport layer
  3. Internet layer
  4. Network Access layer

The Internet layer in the TCP/IP model corresponds to the Network layer in the OSI model. The Network layer in the OSI model provides logical addressing and routing services, and it is responsible for transferring data between different networks. The Internet layer in the TCP/IP model provides similar services, including routing packets between different networks and providing logical addressing through the use of IP addresses.

Therefore, the answer to the question is E. Network. The Network layer of the OSI model is included in the TCP/IP model's Internet layer. The other layers of the OSI model (Application, Presentation, Session, and Data Link) do not directly correspond to any layer in the TCP/IP model. However, their functions are still important in understanding network communication and protocols.
