[amp_mcq option1=”Bus control” option2=”Interrupts” option3=”Bus arbitration” option4=”Status E. None of the above” correct=”option1″]<\/p>\n
The correct answer is A. Bus control<\/strong>.<\/p>\n Bus control pins are used to regulate traffic on the bus, in order to prevent two devices from trying to use it at the same time. This is done by assigning a unique address to each device on the bus, and then using the bus control pins to grant access to the bus to each device in turn.<\/p>\n Interrupts are used to notify the microprocessor of an event that requires its attention. Status pins are used to indicate the current state of the microprocessor.<\/p>\n Bus arbitration is the process of determining which device has access to the bus at any given time. This is done using a variety of methods, such as round-robin arbitration or priority-based arbitration.<\/p>\n None of the other options are correct.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”Bus control” option2=”Interrupts” option3=”Bus arbitration” option4=”Status E.
