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