Which protocol operates at the Network layer of the OSI model?Group of answer choicesUDPTCPHTTPIP

1. Break Down the Problem

The question asks to identify which protocol operates specifically at the Network layer of the OSI model. We need to evaluate the provided options to determine their respective layers.

2. Relevant Concepts

The OSI model has seven layers:

1. Physical Layer
2. Data Link Layer
3. Network Layer
4. Transport Layer
5. Session Layer
6. Presentation Layer
7. Application Layer

Protocols associated with each layer:

• Network Layer: Handles the routing of data and IP addressing (e.g., IP)
• Transport Layer: Manages end-to-end communication (e.g., UDP, TCP)
• Application Layer: Supports application and end-user processes (e.g., HTTP)

3. Analysis and Detail

Now we will analyze each option:

1. UDP: User Datagram Protocol, operates at the Transport Layer.
2. TCP: Transmission Control Protocol, operates at the Transport Layer.
3. HTTP: Hypertext Transfer Protocol, operates at the Application Layer.
4. IP: Internet Protocol, operates at the Network Layer.

4. Verify and Summarize

By evaluating the layer each protocol operates on, we see that the Internet Protocol (IP) is the only protocol listed that functions at the Network layer according to the OSI model.

Final Answer

IP is the protocol that operates at the Network layer of the OSI model.
