Question
Layering is a common approach to tackling large problems in Computers. There are a few common ways of dividing responsibilities on the Internet. One of the most often used is the TC Model. Go online and read up on the TCP/IP Five Layer Model. In your own words write a brief description of the responsibilities of each layer. The Internet routes data packets over the network backbone from router to router to reach their destinations. Looking at the picture above: Host Computer 1 and 2 are on network A, while Host Computer 3 and 4 are on network B. The Router/Gateways in be represent other networks on the internet. If Host 1 is talking with Host 4 using VOIP or Chat, give an example of how each layer plays its part in the communication.Explanation / Answer
Answer: 1
The description of each layer of TCP/IP five layer model is given below:
1. Physical Layer: This layer is basically refer to various hardwares under the network layer. This layer is not very much related to the model as its deal with the hardware and not with the software
2. DataLink Layer: This layer deals with the ip related things. for example the ethernet will work on this leve.
3. Network Layer: This layer provides the network addressing and routing. It also take care about the network reliability. The IP protocol basically operate on this level.
4. Transport Layer: This layer ensure the data consistency. It provides a reliable data transfer between the communicating nodes.
5. Application Layer: This layer provides the various application related services to the user
