Answer:

For I/O-bound we require voluntary context switches.

For CPU-bound we require non-voluntary context switches.

Explanation:

A voluntary context switches occurs when process has given up control of the CPU because it requires a resource that is currently unavailable(such as blocking for I/O). It happen frequently in normal system operation. Voluntary context switching initiated with a call to the sleep() routine.

A non-voluntary context switches occurs when the CPU has taken away from a process, such as when it's time slice has expired or it has been preempted by a high-priority process. It is forced by direct invocation of the low-level context-switching mechanism embodied in the mi_switch() and setrunnable() routines.

Answer:

The answer is "Using the DoD 5220.22-M method and  Degauss media with a magnet".

Explanation:

The "DoD Standard" is a term used during the data sanitizing industry and refers to DoD 5220.22-M. The simplest ways are being used to help eliminate the previously stored data, by deleting hard disc storage facilities with the same data wherever that used a sequence of all zeros.

The sparging eliminates statistics to entirely delete the gravitational flux from electronic media. Hard drives as well as other data storage devices, for example, computer tapes, retain magnetic data. It could no longer be seen as storage after a disk is degaussed.
