The Unix Operating System Kernel maintains two key data structures related to processes, the process table and the user structure. Now, consider the following two statements :

I. The process table is resident all the time and contain information needed for all processes, even those that are not currently in memory.

II. The user structure is swapped or paged out when its associated process is not in memory, in order not to waste memory on information that is not needed.

Which of the following options is correct with reference to above statements ?

  1. Only (I) is correct.
  2. Only (II) is correct.
  3. Both (I) and (II) are correct.
  4. Both (I) and (II) are wrong.
