Virtual Memory is using the Hard Drive as if it were RAM.
Cache is memory for frequently used things and is not stored on the hard drive.
L2n cache
A platter is the portion of a hard disk drive that information is written to.

No volts need a hard drive. However hard drives need a voltage. Usually about 5 for the data more for the physical movement of the drive.
so you can add other cards, hard drive, drives in general, and other stuff.
A pagefile is a reserved portion of a hard disc which is used as an extension of random access memory for data in RAM which hasn't been used recently.
No, C & D might simply be two partitions of one physical drive.
Degaussing (demagnetizing) Physical Destruction Overwriting
physical memory is the actual sticks of memory that you put inside your computer. it is generally faster than logical memory. logical memory is similar to physical memory except imagine all the data on the memory chips on a file in your hard drive. it is usually much slower than physical memory, and it can even damage your hard drive if used in excess. (read/write times increase so the hard drive disk heads have to move faster/more often which puts more wear and tear on the hard drive)
Each disk partition, regardless of whether there are more than one physical drives in the system, is given a drive letter.
