Microprocessor In a microcomputer , the address of memory locations are binary numbers that identify each memory circuit where a byte is stored. If a microcomputer uses 20-bit address, then numbers of different memory locations are 220 - 1 20 220-1 220 220 - 1 20 220-1 220 ANSWER DOWNLOAD EXAMIANS APP
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 More than one device can transmit information over the data bus by enabling only one device at a time The data line can be multiplexed for both input and output 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 More than one device can transmit information over the data bus by enabling only one device at a time The data line can be multiplexed for both input and output It increases the speed of data transfer over the data bus ANSWER DOWNLOAD EXAMIANS APP
