Answer:
RAM provides much faster accessing speed to data than secondary memory. By loading software programs and required files into primary memory(RAM), computer can process data much more quickly. Secondary Memory is slower in data accessing. Typically primary memory is six times faster than the secondary memory.22-Aug-2019

To use
myMethod(2, 7, 12);
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:
An Operating System (OS) is an interface between a computer user and computer hardware. An operating system is a software which performs all the basic tasks like file management, memory management, process management, handling input and output, and controlling peripheral devices such as disk drives and printers.
