Daisy chain bus arbitration:-
In daisy chain bus arbitration the devices which send request to the controller are connected dependently like a chain. The first device gets the priority to send request until it finishes the requests and then next. This arbitration can be stoped if system falls.It's not fast

Four types of bus arbitration?
there are three methods for bus arbitration 1.daisy chain method 2.Independent Bus Requests and Grant method, 3. Polling method more info on dauniv.ac.in/downloads/EmbsysRevEd_PPTs/Chap_2Lesson08EmsysNew.pdf
What is a Bus Arbitration?
Bus arbitration means settlement among different modules. Bus arbiter decides which module work firstly. Bus arbitration is a way of sharing the computer's data transferring channels (buses) in an optimal way so the faster devices won't have to wait to be able to transfer and the slower devices (like peripherals) will have a chance to transfer as well. Different methods exist but two main types are the serial and parallel arbitrations. Serials include the daisy chain arbitration and hardware polling. The parallel ones are software polling and independent requesting.
What is FIFO bus arbitration scheme?
FIFO means First In First Out, so the devices will be served on a first come first served basis.
What is a arbitration?
Bus ArbitrationIn a single bus architecture when more than one device requests the bus, a controller called bus arbiter decides who gets the bus, this is called the bus arbitration. Arbitration is mostly done in favor of a master micro processor with the highest priority.
With aid of suitable diagram explain the computer Bus interconnection scheme.?
A bus is a communication path way connectign 2 or more devices.
Which type of physical topology uses a single length of cable end to end?
A bus topology uses cable to go from one device to another, in a daisy chain. There are no other devices required, such as hubs, switches, repeaters, etc.
How many devices can be daisy chained from one usb?
A personal computer external bus standard which can support up to 127 peripheral devices in a daisy chain configuration, can support plug-and-play (hot plugging), and has a total bandwidth of 1.5 megabytes per second. what are these devices?
What is serial bus arbitration?
In serial bus, if there are multiple masters, then multiple master decides whether it acquires the bus or not using data pattern. In case where master needs to drive 0, it would drive other wise it would release. Master would always figure out whehter it has acquired the bus or not by checking the bus being equal to 1 when it is not driving. If it is driven as 0, then it would understand that it is occupied by other master. So it would release the bus.
What allows you to connect a monitor and a printer to a notebook computer via one connection as opposed to connecting individual devices?
The original idea for the Universal Serial Bus or USB was that you would be able to "daisy-chain" devices one to another. This worked, until device manufacturers realized that they could draw power from the USB circuit to power the device. You can't daisy-chain devices and still draw power from them. An earlier version of the same concept, the Small Computer System Interface or SCSI would (in theory!) allow you to daisy-chain no more than 7 devices together. But the devices were only compatible in theory, and the configuration was sometimes a bit tricky. This also required you to manually set a unique identifier for each device.
What is auto bus transfer scheme?
As per two incomers and one buscoupler configuration , buscoupler automatically close after tripping of any one of incomer will trip under fault condition or u/v condition or there is no voltage in bus ie dead bus closing.
Which ID number is normally assigned to the SCSI controller?
The ID number which is traditionally assigned to the SCSI controller is ID 7. ID 7 is given the highest priority during bus arbitration.
What are computer bus standard?
computer buses were literally parallel electrical wires with multiple connections, but the term is now used for any physical arrangement that provides the same logical functionality as a parallel electrical bus. Modern computer buses can use both parallel and bit serial connections, and can be wired in either a multidrop (electrical parallel) or daisy chain topology, or connected by switched hubs, as in the case of USB.
