Which of the following describes the correct order of the TCP/IP model?

1. Application, Internetwork, Transportation, Network Access

2. Application, Network Access, Internetwork, Transportation

3. Application, Transportation, Internetwork, Network Access

4. Network Access, Application, Network Access, Transportation

The correct answer is: Application, Transportation, Internetwork, Network Access

The correct order of the TCP/IP model is as follows: Application, Transportation, Internetwork, and Network Access. This model, which is fundamental in networking, provides a framework for the communication process. The Application layer is the top layer and is responsible for enabling end-user services and applications. It encompasses protocols that applications use to communicate over the network, such as HTTP, FTP, and SMTP. Following the Application layer is the Transportation layer, which is responsible for end-to-end communication and data transfer. It includes protocols like TCP (Transmission Control Protocol) and UDP (User Datagram Protocol), which ensure that data packets are transmitted reliably or in a streamlined manner, respectively. Next is the Internetwork layer, which provides routing and addressing capabilities to ensure that data can traverse different networks and reach the correct destination. This layer utilizes protocols like IP (Internet Protocol). Finally, the Network Access layer, also referred to as the Network Interface layer, deals with the physical aspects of network communication and encapsulates the processes of framing data for transmission over the physical network medium. The other provided options incorrectly sequence the layers, resulting in a misunderstanding of the architecture and functionality of the TCP/IP model. Each layer has a distinct role, and following the proper sequence is essential for anyone
