TCP/IP model does not have _______ layer but OSI model have this layer...
TCP / IP model is a communications protocol to interconnect network devices on the internet. TCP / IP model is different from the OSI standard in that, it has 4 layers while OSI has seven layers. It has an Application layer, transport layer, internet layer, and network access layer. Session Layer and Presentation layer is not present in the TCP/IP model.

TCP/IP Model and OSI Model
The TCP/IP model and the OSI model are two different models used to describe network communication. The TCP/IP model is used for the internet and the OSI model is used for general communication. Both models have layers that describe the different aspects of network communication.
Layers of TCP/IP Model
The TCP/IP model has four layers, which are as follows:
1. Application Layer: The Application Layer is responsible for providing services to the user. It includes protocols such as HTTP, FTP, SMTP, and Telnet.
2. Transport Layer: The Transport Layer is responsible for providing reliable communication between applications. It includes protocols such as TCP and UDP.
3. Internet Layer: The Internet Layer is responsible for providing logical addressing and routing of packets. It includes protocols such as IP, ICMP, and ARP.
4. Network Interface Layer: The Network Interface Layer is responsible for providing physical addressing and access to the network media. It includes protocols such as Ethernet and Wi-Fi.
Layers of OSI Model
The OSI Model has seven layers, which are as follows:
1. Application Layer: The Application Layer is responsible for providing services to the user. It includes protocols such as HTTP, FTP, SMTP, and Telnet.
2. Presentation Layer: The Presentation Layer is responsible for translating data from the application layer into a format that can be understood by the network. It includes protocols such as JPEG and MPEG.
3. Session Layer: The Session Layer is responsible for establishing, maintaining, and terminating sessions between applications. It includes protocols such as NetBIOS and RPC.
4. Transport Layer: The Transport Layer is responsible for providing reliable communication between applications. It includes protocols such as TCP and UDP.
5. Network Layer: The Network Layer is responsible for providing logical addressing and routing of packets. It includes protocols such as IP, ICMP, and ARP.
6. Data Link Layer: The Data Link Layer is responsible for providing physical addressing and access to the network media. It includes protocols such as Ethernet and Wi-Fi.
7. Physical Layer: The Physical Layer is responsible for transmitting raw data over a physical medium. It includes protocols such as RS-232 and V.35.
Missing Layer in TCP/IP Model
The Session Layer is missing in the TCP/IP model. This layer is responsible for establishing, maintaining, and terminating sessions between applications. The TCP/IP model does not have this layer because it assumes that the applications will handle these functions themselves. However, some TCP/IP protocols such as FTP and Telnet perform session management functions at the application layer.
Conclusion
In conclusion, the TCP/IP model and the OSI model are two different models used to describe network communication. The TCP/IP model has four layers, while the OSI model has seven layers. The Session Layer is missing in the TCP/IP model, but some protocols perform session management functions at the application layer.
