which osi layer is responsible for the ethernet network
The Ethernet network operates at the Data Link Layer (Layer 2) of the OSI model. This layer is responsible for handling data frames, including addressing, error detection, and flow control, within the local network.
The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a communication system into seven different layers.
In the context of Ethernet networks, the Ethernet protocol itself operates mainly at the Physical layer (Layer 1) and the Data Link layer (Layer 2) of the OSI model.
At the Physical layer, the Ethernet protocol defines the electrical, mechanical, and functional specifications of the physical medium used for communication, such as cables, connectors, and signal encoding schemes.
At the Data Link layer, the Ethernet protocol implements two sublayers: the Logical Link Control (LLC) sublayer and the Media Access Control (MAC) sublayer. The LLC sublayer is responsible for managing access to the physical medium and providing flow control and error detection services. The MAC sublayer is responsible for the addressing of devices on the network, media access control, and frame encapsulation and decapsulation.
Therefore, the Ethernet network primarily operates at the Physical layer and the Data Link layer of the OSI model.
