4. What I Cover In This Presentation What is Distributed Arbitration? Why Distributed Arbitration is most reliable bus arbitration system?​ How is a device selected in distributed arbitration?​ Explain the Distributed Arbitration Diagram? Conclusion​ Advantage and Disadvantag e of Distributed Arbitration.

5. What is Distributed Arbitration? When one or more devices request control of the bus, they assert the start arbitration signal and place their 4-bit identification numbers on arbitration lines through ARB3. In distributed arbitration, all devices participate in the selection of the next bus master. In this scheme each device on the bus is assigned a4-bit identification number.​

6. Why Distributed Arbitration is most reliable bus arbitration system?​ Distributed Arbitration Each device compares the code and changes its bit position accordingly. It does so by placing a 0 at the input of their drive. The distributed arbitration is highly reliable because the bus operations are not dependent on devices.

7. How is a device selected in distributed arbitration?​ By NANDing the signals passed on all the 4 lines By ORing the signals passed on all the 4 lines By ANDing the signals passed on all the 4 lines None of the mentioned

8. Advantage and Disadvantag e of Distributed Arbitration. The Distributed Arbitration is highly arbitration reliable because the less operations are not dependent on devices. Advantage Disadvantage Disadvantage Advantage Distributed Arbitration It is less secure than centralized arbitration as data is distributed across several devices. Only one device can access the bus or only one device can be a bus master at a time. As it is not centralize, even if one or two computer goes down, the entire system does not crash.

9. Explain The Distributed Arbitration Diagram

10. Conclusion As a conclusion, buses are actually helpful as its act as a vital medium in order to transferring data. Therefore, bus arbitration also important. I think distributed Bus arbitration is better between centralized bus arbitration. Although it has some drawbacks. But the distributed arbitration is highly reliable because the bus operations are not dependent on devices.
