Which of the following is a type of storage that is non-volatile and uses no moving parts? MCQ with Answer and Explanation

Explanation:
Hard disk capacity is typically expressed in bytes (e.g., gigabytes, terabytes). Bits are used for data rates, hertz for frequency, and watts for power.

Explanation:
Hard Disk Drives use platters coated with magnetic material and magnetic heads to alter and read polarization patterns representing binary data.

Explanation:
For DDR memory, the effective data rate is often quoted in MT/s (megatransfers per second), which indicates the number of data transfers per second. MHz is clock frequency, which is half of MT/s for DDR.
