Microprocessor The output data lines of microprocessor and memories are usually tristated because More than one device can transmit over the data bus at the same time It increases the speed of data transfer over the data bus The data line can be multiplexed for both input and output More than one device can transmit information over the data bus by enabling only one device at a time More than one device can transmit over the data bus at the same time It increases the speed of data transfer over the data bus The data line can be multiplexed for both input and output More than one device can transmit information over the data bus by enabling only one device at a time ANSWER DOWNLOAD EXAMIANS APP
