Consider a single-platter disk with the following parameters: rotation speed: 7200 rpm; number of tracks on one side ofplatter:
horsena [70]

Answer:

Given Data:

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 0. 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

Write a program that prompts the user to enter a string and displays the maximum consecutive increasingly ordered substring. Ana
Marianna [84]

Answer:

a.

// Program is written in Java Programming Language

// Comments are used for explanatory purpose

// Comments marked x represents simple statements

// Comments marked y represents single loop

// Program starts here

import java.util.*;

public class MaxOrder {

public static void main(String args [] ) {

Scanner accept = new Scanner(System.in);

LinkedList<Character> maxtext = new LinkedList<>();

LinkedList<Character> textlist = new LinkedList<>();

System.out.print("Enter a text: ");

String text = accept.nextLine();

// Find the maximum consecutive increasingly ordered substring

for (int i = 0; i < text.length(); i++) { // y1

if (textlist.size() > 1 && text.charAt(i) <= textlist.getLast() && textlist.contains(text.charAt(i))) {

textlist.clear(); // x

}

textlist.add(text.charAt(i)); // x

if (textlist.size() > maxtext.size()) { // x

maxtext.clear();

maxtext.addAll(list);

}

}

// Display the maximum consecutive

// increasingly ordered substring

for (Character ch: maxtext) { // y2

System.out.print(ch); // x

}

System.out.println();

}

b. Analysing the time complexity

In single loop marked y1, there are 3 simple statements ----- 1

In single loop marked y2, there is 1 simple statement --_--- 2

In (1) above,

1 single loop * 3 simple statements = 3;

*

In (2) above,

1 single loop * 1 simple statement = 1;

So, we have

T(n) = O(n) Linear time
