It's two. You have it right.
DUAL PLATFORM - Yes you can have two operating system in one hard drive.
The hard drive has to be partitioned into at least two drives. Each can be loaded with a separate bootable operating system.
"Hardware" is one word.
Hard Drive configuration is used to define the Slave and master Hard Drive. When we are attaching more than one hard drive the configuration is used. Configuration is done by jumper setting which is available in back side of hard drive...1st two pins for master hard drive and last pins are slave..
The hard disk drive platter is used to store magnetic data or information that comes from the hard disk drive, where they are stored. The hard disk drive can contain one or more hard disk platter.
Each disk partition, regardless of whether there are more than one physical drives in the system, is given a drive letter.
no.
Hard work is written as two separate words.
If there is one partition in a hard disk and one CD device then the default drive letter assigned is D. Else, If there are two partitions in a hard disk and one CD device then the default drive letter assigned is E. Else, If there is only one partition in a hard disk and two CD devices then the default drive letters assigned to both CD devices are D and E.
There is no requirement that one or the other is the Master or Slave, as long as one of them is (if they are on the same cable.)
No, C & D might simply be two partitions of one physical drive.
"Hard drive" may be regarded as a compound noun, but traditionally, "hard" would be regarded as an adjective and "drive" as a noun. A justification for considering the two word phrase a single noun is that this phrase implies considerably more than merely a drive that is hard; it also implies storage capacity and read and write memory as a computer component. A golf stroke could also be called a "hard drive", for example, but in that instance the phrase has no substantial additional implications that are not comprehended within the normal meanings of "hard" and "drive" separately in the context.
