Answer: Multiplexing
Explanation:
By using the multiplexing technique we can easily use the multiple digit display in the input pins of the hardware. We can use this technique to display the several digits and the extra hardware is require which is proportional to the number of several digit to be display.
As, hardware use only limited number of input and output pins. Therefore, multiplexing is the technique used the number of hardware chips need for multiple digit display and can be minimize using this technique.
