Consider a disk with an average seek time of $4$ ms.

Motor speed 15000RPM

512B sector

500 sector per track

A file occupies all of the sectors on $5$ tracks

Each track reading requires average seek time and average rotational delay

• What will be transfer time of $1$ track?

mam, I think transfer rate/speed should be given in question.

Transfer time for 1 track = (total data available in 1 track)/ Transfer speed = (500*512 Bytes)/ transfer speed.

If we consider that data of 1 track is transferred in 1 rotation.

Then 15000 RPM means 15000 rotations in 1 minute (or) 1 rotation in 1/15000 minutes (or) data of 1 track can be transferred in 1/15000 minutes.

@ankitgupta.1729

(500*512 Bytes)/ transfer speed.?

or

1/15000 minutes. ?

if we take a real life example

Can we think transfer time means transfer time means just some byte is transferring?

What is transfer time actually means?

mam, 1/15000 min since transfer rate is not given. Here , Arjun sir also has done the same thing.

transfer time simply means time taken to transfer some data from one place to other.

how?

It is asking for 1 track

1 track means 500 sector

and 1 sector can store 512B
