- - - - IEEE 802.2
      - provides flow control and error control and allows multiple protocols to work simultaneously.
      - Interacts directly with the network layer
    - - IEEE 802.3
        
        Defines Carrier Sense Multiple Access/Collision Detection (CSMA/CD), which is used to handle data collisions.
      - Defines how packets are placed onto the physical media at the Physical layer.
  - - - It used to be a permanent address that was written into, or burned into, the read-only-memory (ROM) chip on the network interface card (NIC), but it is usually stored on the NIC’s firmware today.
  - - - Create separate collision domains
        
        Learns the MAC addresses of devices that are connected to a port similar to how a switch learns these MAC addresses.
        
        A bridge will typically have multiple computers connected to each bridge port via a hub.
    - - Create separate collision domains
        
        Learns MAC addresses of devices to segment traffic.
    - - It is shared between the Data Link layer and Physical layer.
      - Includes the layer 2 MAC address that is used at layer 2.
