What is R/W?

R/W is Read/Write.

Tell the reason any one.

I know only, the cylinder is nothing but group of disks. So, these group of disks (cylinder) can't help to provide the movement of read/write head.

Track (track number N) from all discs (vertically) forms a cylinder.
Since cylinder is rotating we no need to move the R/W head to access the data.

Does it really mean that the entire platter is the cylinder?

Cluster is wright answer.

Cylinders are vertically formed by tracks. In other words, track 12 on platter 0 plus track 12 on platter 1 etc. is cylinder 12. The number of cylinders of a disk drive exactly equals the number of tracks on a single surface in the drive.
So, in order to access a particular cylinder from a track we do not need to move R/W head from that particular track.

Because the total no of cylinders in a disk exactly equals the number of tracks on a single surface in the drive.
