Final answer:
The ISO/OSI model has 7 layers while the TCP/IP model has 4 layers.
Step-by-step explanation:
The ISO/OSI model has 7 layers. These layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
The TCP/IP model, on the other hand, has 4 layers. These layers are: Network Interface, Internet, Transport, and Application.
It's important to note that the layers in the TCP/IP model do not align exactly with the layers in the ISO/OSI model. For example, the TCP/IP Network Interface layer combines functionality from the Physical and Data Link layers of the ISO/OSI model.
