Can you please tell me which one below is right or wrong:
1) all similar hardware devices will share the same device driver (R/W)
2) Main memory is usually faster than secondary storage devices (R/W)
3) Main memory is usually cheaper per unit in comparison with secondary storage devices (R/W)
Thank you
