What are the layers of the OSI model?

The OSI (Open Systems Interconnection) model is a conceptual framework used to understand and implement the interactions between different networking systems. It consists of seven distinct layers, each responsible for specific functions in the process of data communication. The correct choice accurately lists all seven layers of the OSI model:

1. Physical Layer: This layer deals with the physical connections between devices, including cables, switches, and the electrical signals that traverse the medium.
2. Data Link Layer: It provides node-to-node data transfer and error detection and correction from the Physical layer.

3. Network Layer: Responsible for routing packets across the network, managing traffic, and addressing.
4. Transport Layer: This layer ensures complete data transfer and manages error recovery and flow control.
5. Session Layer: It establishes, maintains, and terminates communication sessions.
6. Presentation Layer: Responsible for data translation, encryption, and compression, this layer ensures that data is presented in a readable format.
7. Application Layer: The topmost layer that interacts directly with software applications to provide network services.

Understanding the OSI model is crucial for troubleshooting and developing network architectures, as it provides a universal language for different networking
