Which layer in the Transmission Control Protocol/Internet Protocol (TCP/IP) model does IP use? 1 pointNetworkData LinkPhysicalTransport

Step 1: Break Down the Problem

The question is asking about the specific layer in the TCP/IP model that the Internet Protocol (IP) operates within. To answer this, we need to understand the layers of the TCP/IP model.

Step 2: Relevant Concepts

The TCP/IP model consists of the following layers:

1. Application Layer: This is the topmost layer that interfaces directly with the end user and handles application-level protocols.
2. Transport Layer: This layer is responsible for reliable transmission of data segments between points on a network, managing flow control and error correction.
3. Internet Layer: This layer manages logical addressing and routing of data packets across a network; this is where the Internet Protocol (IP) operates.
4. Network Interface (or Data Link) Layer: This is responsible for the physical transmission of data over the network.

Step 3: Analysis and Detail

Based on the structure of the TCP/IP model, IP specifically functions at the Internet Layer. It is responsible for the addressing and routing of packets of data from the source to the destination across multiple networks.

Step 4: Verify and Summarize

Given the definitions and roles of the layers in the TCP/IP model, it is confirmed that:

• IP operates within the Internet Layer of the TCP/IP model.

Final Answer

Internet Layer (IP uses the Internet layer in the TCP/IP model)
