If an address bus needs to be able to address eight devices, how many conductors will be required? What if each of those devices also needs to be able to talk back to the I/O control device?
Would it be 8 since each data line carries one byte of information?© BrainMass Inc. brainmass.com March 4, 2021, 9:22 pm ad1c9bdddf
We need 8 conductors for the data line since it carries one byte of information or 256 possible values, as each conductor can carry either a 0 or a 1.
To be able to address 8 devices (numbered 0-7), address bus ...
Solution also gives a formula to compute number of address bus conductors, when address bus needs to be able to address N devices.
