A single-platter disk has rotation speed 7200 rpm, number of tracks on one side of platter is 30,000, number of sectors per trac
nexus9112 [7]

Answer:

Rotation Speed = 7200 rpm

No. of tracks on one side of platter = 30000

No. of sectors per track = 600

Seek time for every 100 track traversed = 1 ms

To find:

Average Seek Time.

Average Rotational Latency.

Transfer time for a sector. Total Average time to satisfy a request.

Explanation:

a) As given, the disk head starts at track O. At this point the seek time is 0.

Seek time is time to traverse from 0 to 29999 tracks (it makes 30000)

Average Seek Time is the time taken by the head

to move from one track to another/2

29999 / 2 = 14999.5 ms

As the seek time is one ms for every hundred

tracks traversed. So the seek time for 29,999 tracks traversed is

14999.5/100 = 149.995 ms

b) The rotations per minute are 7200

1 min = 60 sec

7200 / 60 = 120 rotations / sec

Rotational delay is the inverses of this. So 1/120 = 0.00833 sec

= 0.00833 * 100

= 0.833 ms

So there is 1 rotation is at every 0.833 ms

Average Rotational latency is one half the amount of time taken by disk to make one revolution or complete 1 rotation.

So average rotational latency is: 1 / 2r

8.333/2 = 4.165 ms

c) No. of sectors per track = 600

Time for one disk rotation = 0.833 ms

So transfer time for a sector is: one disk revolution time / number of sectors

8.333 / 600 = 0.01388 ms = 13.88 μs

d) Total average time to satisfy a request is calculated as :

Average seek time + Average rotational latency + Transfer time for a sector

= 149.99 ms + 4.165 ms + 0.01388 ms

= 154.168 ms

the reduction of carbon dioxide emissions poses few threats to sustaining economic growth in developing countries.
Oksi-84 [34.3K]

It is false that the reduction of carbon dioxide emissions poses few threats to sustaining economic growth in developing countries.

Given that the reduction of carbon dioxide emissions poses few threats to sustaining economic growth in developing countries.

We are required to say whether the statement is true or false.

Economic growth basically defined as the increase or improvement in the inflation-adjusted market value of the goods and services produced by an economy over a certain period of time.

The reduction of carbon dioxide emissions does not poses threats but benefits our country and in result lead to increase in economic growth of the countries.

Hence it is false that the reduction of carbon dioxide emissions poses few threats to sustaining economic growth in developing countries.
