Effect of changing the # wires in the data bus

Recall:

Effect of changing the # wires in the data bus
 

Effect of changing the # wires in the data bus
 

Effect of changing the # wires in the data bus - an analogy

One Wire in the data bus transfer one bit of data - like one lane in a high way:

 

More wires in the data bus allow the Computer System to transfer more bits in one data transfer operation

Effect of changing the # wires in the data bus - postscript
 

Effect of changing the # wires in the address bus

Recall:

Effect of changing the # wires in the address bus

 

Effect of changing the # wires in the address bus

 

Therefore:

(So a computer with 8 bits address bus can identify (= have) maximum 28 RAM memory)

Effect of changing the # wires in the address bus

 

Therefore:

( Computers with 16 bits address bus can identify (= have) maximum 216 RAM memory)

Effect of changing the # wires in the address bus
