10.Question 10Which layer abstracts away the need for any other layers to care about what hardware is in use? 1 pointTransportPhysicalNetworkData Link

Problem Breakdown

We need to identify which layer of the OSI model abstracts the hardware specifics from the other layers.

Relevant Concepts

The OSI (Open Systems Interconnection) model describes how different networking layers interact and communicate. The layers mentioned in the question are:

1. Transport
2. Physical
3. Network
4. Data Link

Analysis and Detail

1. Transport Layer: This layer is responsible for end-to-end communication and data flow control. It doesn't manage hardware specifics.

2. Physical Layer: This layer deals with the actual hardware transmission of raw bitstreams over a physical medium. It does not abstract the hardware specifics from upper layers.

3. Network Layer: This layer is responsible for routing data and packet forwarding. It doesn't abstract hardware specifics either.

4. Data Link Layer: This layer provides node-to-node data transfer and error detection. While it interacts with hardware, it still requires knowledge of the underlying physical layer.

Verify and Summarize

None of the layers mentioned fully abstracts away hardware concerns like the Transport layer does. The Transport layer focuses on managing communication regardless of the hardware being used.

Final Answer

The correct answer is: Transport Layer.
