Question

If a magnetic disc has 100 cylinders, each containing 10 tracks of 10 sectors, and each sector can contain 128 bytes, what is the maximum capacity of the disk in bytes?

Answer 1

The maximum capacity of the disk is 1280000 bytes.

Given data :

1 sector contains 128 bytes.

There are 10 sectors in one track.

One cylinder contains 10 tracks.

There are 100 cylinders.

• The total number of tracks

= Number of cylinders × Tracks in one cylinder

= 100×10

= 1000

• Number of sectors

= Number of tracks × Sectors in one track

= 1000×10

= 10000

• Total amount of data

= Total number of sector × data present in one sector

= 10000×128

= 1280000 bytes

The total capacity of data in terms of bytes is 1280000 bytes. (Answer)
