  3. 3.  CAN bus is a vehicle bus standard designed to allow microcontroller and devices to communicate with each other in vehicle.  It is a message based protocol.  It is present in both physical and data link layer of OSI layers.  It is a multi-master serial bus .
  4. 4.  Stand alone CAN Controller.  Integrated CAN Controller.  Single-Chip CAN Controller.
  5. 5.        Start of Frame. Arbitration Field. Control Field. Data Field. CRC Field. Acknowledgement bits. End of Frame.
  6. 6.   Standard Data Frame Extended Data Frame
  7. 7.      Automobiles Aerospace Maritime Industrial automachine Medical equipments
  8. 8.   High throughput under light loads Local and global prioritization possible
  9. 9.   Unfair access - node with a high priority can "hog" the network. Poor latency for low priority nodes.
  10. 10.  CAN is ideally suited in applications requiring a large number of short messages with high reliability in rugged operating environments. Because CAN is message based and not address based, it is especially well suited when data is needed by more than one location and system-wide data consistency is mandatory.
