What is meant by quad-density(QD) diskette?
The correct option is B All of the above
A quad density disk is a 5¼" floppy disk with a
storage capacity of 720 kilobytes. Quad density floppy disks are often double
sided. During their time, quad density floppy disks are not as common as
double-sided, double-density floppy disks.
In computer science, a double-sided disk is a disk of
which both sides are used to store data. Early floppy disks only used one
surface for recording. The term single-sided disk was not common until the
introduction of the double-sided disk, which offered double the capacity in the
same physical size.
A double density disk is a floppy diskette capable of
holding twice the amount of information as a single-density disk. A DD disk can
hold 720 KB of data. Today, these diskettes are obsolete.
TPI. Short for Tracks Per Inch, TPI is the number of
tracks a disk can hold. For example, a 5.25-inch floppy disk (double density)
has 48 TPI; a high-density 3.5-inch disk has 135, and hard drives have much
higher TPIs, well into the thousands.
