Which layer of the OSI model does Project 802 divide into two sublayers?1 pointPhysicalData LinkNetworkSession

The OSI (Open Systems Interconnection) model is a conceptual framework used to understand and implement network protocols in seven layers. Project 802, developed by the IEEE (Institute of Electrical and Electronics Engineers), specifically addresses the standards for local area networks (LANs) and metropolitan area networks (MANs).

Here is the step-by-step answer to the question:

1. Identify the OSI Model Layers: The OSI model consists of seven layers:

   • Physical
   • Data Link
   • Network
   • Transport
   • Session
   • Presentation
   • Application

2. Understand Project 802: Project 802 is a set of standards for LANs and MANs, which includes various protocols and services.

3. Determine the Layer in Question: The question asks which layer of the OSI model is divided into two sublayers by Project 802.

4. Focus on the Data Link Layer: The Data Link layer (Layer 2) of the OSI model is the layer that Project 802 divides into two sublayers.

5. Identify the Two Sublayers:

   • Logical Link Control (LLC): This sublayer is responsible for identifying and encapsulating network layer protocols, and controls error checking and frame synchronization.
   • Media Access Control (MAC): This sublayer is responsible for controlling how devices on a network gain access to the medium and permission to transmit data.

6. Conclusion: The Data Link layer of the OSI model is the layer that Project 802 divides into two sublayers: the Logical Link Control (LLC) sublayer and the Media Access Control (MAC) sublayer.

So, the correct answer is: Data Link
