A magnetic disk has a sector size of $\mathbf{512}$ bytes. Each sector is identified by a $\mathbf{28}$-bit sector number.

What is the maximum disk capacity that can be managed?

For this question, take $:512\times 2^{21}\ \mathrm{bytes}=1\ \mathrm{GB}$

  1. $32\ \mathrm{GB}$
     
  2. $64\ \mathrm{GB}$
     
  3. $128\ \mathrm{GB}$
     
  4. $256\ \mathrm{GB}$
