Solution

The magnetic HDD storage in computers uses the NRZ (Non-Return to Zero) encoding technique to read and write the information stored on it.

Here's a step-by-step explanation:

  1. When data is stored on a hard disk drive (HDD), it is encoded into binary format (1s and 0s).

  2. The NRZ encoding technique is used to represent this binary data. In NRZ encoding, a binary 1 is represented by a high voltage and a binary 0 is represented by a low voltage.

  3. The NRZ encoding technique is preferred because it is simple and does not require a lot of processing power to implement.

  4. When data is read from the HDD, the NRZ encoded data is decoded back into its original format.

So, the correct answer is a. NRZ.
