How we can find the 1's complement?

What is R/W?

My dear friends each cylinder is having R/W head.

Please refer: http://en.wikipedia.org/wiki/Cylinder-head-sector#Cylinders.

I think this question and answer is wrong. R/W head should be re-positioned to access the cylinder. What Mr.Sundar said is correct "Track (track number N) from all discs (vertically) forms a cylinder". There is only one r/w head for each disk surface. So to access each cylinder (tracks on each disk) head should move.

This question should be "The part on a disk which can be accessed without re-positioning the R/W heads is" and the answer is SURFACE.

Please explain the terms-surface, cluster & cylinder on disc.

I could not understand this. Please explain.

Cluster & Surface are scatter. The R/W head has to move forward and backward. So from this, All of the Above option is wrong.

Cylinder is the Plate itself. So the R/W head always touch it. :-).

R/W is Read/Write.

Cylinder is one of the size method of disk.

Tracks are concentric circles divided on the surface of plate of hard disk. As there are more than one plate in hard disk. This circles and plates looks like cylinder. Here I can't so diagrammatically but understand me. It is other name for tracks.

About cluster it is term that defines allocation of memory in file system. Fs like ntfs produces clusters during formatting and its size is defined during formatting.
