Which layer of the TCP/IP model is responsible for accepting and delivering packets in a network?1 分InternetNetwork Access Transport Application

Break Down the Problem

1. Identify the layers of the TCP/IP model.
2. Determine which layer is responsible for packet accepting and delivering.

Relevant Concepts

The TCP/IP model consists of four layers:

1. Application Layer: Deals with application-level protocols and user interfaces.
2. Transport Layer: Responsible for end-to-end communication, error recovery, and flow control.
3. Network Access Layer: Includes protocols that control the physical and logical connections, dealing with how data is transmitted over the network.
4. Internet Layer: Handles the routing of packets across different networks.

Analysis and Detail

In TCP/IP, the Internet Layer is primarily responsible for addressing and routing packets from the source host to the destination host across multiple networks. This layer creates packets and ensures they are delivered to the correct destination by using IP addresses. The Network Access Layer, on the other hand, deals with the hardware addressing (like MAC addresses) and the transmission media over which the data packets travel.

Verify and Summarize

To summarize, while both the Internet Layer and the Network Access Layer are involved in the delivery of packets, the Internet Layer specifically focuses on the acceptance and delivery of packets across interconnected networks.

Final Answer

The layer responsible for accepting and delivering packets in a network is the Internet Layer.
