Understanding OSI and TCP/IP Models

Which layer of the OSI model is responsible for routing packets across network boundaries?

• Physical Layer

• Data Link Layer

• Network Layer

• Transport Layer

In the TCP/IP model, which layer is equivalent to the OSI model's Application, Presentation, and Session layers?

• Network Interface Layer

• Internet Layer

• Transport Layer

• Application Layer

What is the primary function of the Transport Layer in the OSI model?

• Data encryption

• Packet routing

• End-to-end communication and error recovery

• Physical data transmission

Which protocol operates at the OSI model's Transport Layer?

• HTTP

• TCP

• IP

• Ethernet

During the data encapsulation process, which layer adds a header to the data?

• Application Layer

• Presentation Layer

• Network Layer

• Data Link Layer

Which of the following is NOT a layer in the OSI model?

• Application Layer

• Internet Layer

• Presentation Layer

• Session Layer

In the TCP/IP model, which layer is responsible for logical addressing and routing?

• Application Layer

• Transport Layer

• Internet Layer

• Network Interface Layer

Which layer of the OSI model is responsible for data format translation and encryption?

• Application Layer

• Presentation Layer

• Session Layer

• Transport Layer

What is the main difference between the OSI and TCP/IP models?

• OSI has 5 layers, TCP/IP has 7 layers

• OSI is a theoretical model, TCP/IP is a practical model

• OSI is used for wireless networks, TCP/IP is for wired networks

• OSI is older than TCP/IP

Which protocol is used at the Internet Layer of the TCP/IP model?
