he will need a microphone, it is a recording device.
The
answer is FALSE because the
interior of commercial Hard disk drive is with stack of magnetic disks
(platters) containing the user’s data and a rotating arm supporting the magnetic
heads. The rotating arm is moved by the torque generated by a voice coil motor
(VCM) mounted at one end of the arm. Data read/write operations rely on the capability of the
governing unit of the HDD to maintain the magnetic read/write heads as close as
possible to center of the desired track. Typically, reliability of data reading
and writing is guaranteed when the head is kept within 5% of the track pitch
from the track center. This means that the accuracy required for the head positioning
is in the range of a few tens of nanometers.

Answer: A class that implement an interface must contain methods for all abstract methods in the interface. Otherwise, the class must be declared as abstract.
Explanation:
It is necessary to implement all the abstract method that are present in the interface. Basically, this is one of the rule of abstract method. As, abstract method is define as without any implementation.
If any class contain abstract method then, it must be declare as abstract. Therefore, if a class are not implemented an interface method then, it should be declare as abstract.
