With the aid of a clearly labeled diagram, illustrate and demonstrate your researchexplaining on the function of each of the seven layers of the OSI model.

The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a communication system into seven distinct categories, or layers. Here's a brief explanation of each layer:

1. Physical Layer (Layer 1): This is the lowest layer of the OSI model. Its function is to transfer raw bitstream over the physical medium like cables or wireless media. It provides the hardware means of sending and receiving data on a carrier network.

2. Data Link Layer (Layer 2): This layer is responsible for node-to-node data transfer. It provides error detection and correction to ensure data is sent and received accurately. It also defines the protocol for device MAC addresses.

3. Network Layer (Layer 3): This layer is responsible for the transfer of data from one node to another located in different networks. It manages network congestion and determines the best path for data transfer (routing).

4. Transport Layer (Layer 4): This layer is responsible for end-to-end communication between the source and the destination. It provides mechanisms for the establishment, maintenance, and termination of virtual circuits, transport fault detection and recovery, and information flow control.

5. Session Layer (Layer 5): This layer is responsible for establishing, managing, and terminating connections between applications. It provides full-duplex, half-duplex, or simplex operation and establishes checkpointing, adjournment, termination, and restart procedures.

6. Presentation Layer (Layer 6): This layer is responsible for data representation and code formatting. It ensures that data is in a readable format for the application layer.

7. Application Layer (Layer 7): This is the topmost layer of the OSI model. It provides services for an application to ensure that effective communication with another application process on a network is possible. It provides services such as file transfer, email, and other network software services.

Unfortunately, I can't provide a diagram here, but you can easily find OSI model diagrams online that clearly label each of these seven layers.
