Question

In a TCP/IP model, which of the following is the layer responsible for routing packets between different networks?

• A. Application layer
• B. Transport layer
• C. Network layer
• D. Data Link layer

Hint:

The Network layer is key to routing and forwarding packets across different networks.

Answer 1

The Correct Option is C

The TCP/IP model is a conceptual framework that standardizes the functions of a communication system. The model consists of four layers: Application, Transport, Network, and Data Link.
Step 1: The Network layer is responsible for routing packets between different networks. It determines how data is sent to the receiver from the source by using logical addressing (e.g., IP addresses).
Step 2: The Transport layer is responsible for the end-to-end communication and data flow control, not for routing packets between networks.
Step 3: The Data Link layer is responsible for the physical transmission of data over a link and does not handle routing between networks. Thus, the correct answer is Network layer.
Step 4: The Application layer deals with high-level protocols such as HTTP, FTP, etc., and is not concerned with routing.
