Zoom Vacuum, a family-owned manufacturer of high-end vacuums, has grown exponentially over the last few years. However, the company is having difficulty preparing for future growth. The only information system used at Zoom is an antiquated accounting system. The company has one manufacturing plant located in Iowa; and three warehouses, in Iowa, New Jersey, and Nevada. The Zoom sales force is national, and Zoom purchases about 25 percent of its vacuum parts and materials from a single overseas supplier. You have been hired to recommend the information systems Zoom should implement in order to maintain their competitive edge. However, there is not enough money for a full-blown, cross-functional enterprise application, and you will need to limit the first step to a single functional area or constituency. What will you choose, and why?

Answers

Answer 1

Answer:

The best advice for Zoom Vacuum is  to start with a Transaction Processing System(TPS). This system will process all the day to day transactions of the system. It is like a real time system where users engage with the TPS and generate, retrieve and update the data. it would be very helpful in lowering the cost of production and at the same time manufacture and produce standard quality products.

Although, TPS alone would not be sufficient enough. so Management Information System(MIS) would be needed, that can get the data from the TPS and process it to get vital information.

This MIS will bring about information regarding the sales and inventory data about the current and well as previous years.

With the combination of TPS as well as MIS is a minimum requirement for a Zoom Vacuum to become successful in the market.

Explanation:

Solution

When we look at the description of the Zoom Vacuum manufacturing company closely, we see that the business is currently a small scale business which is trying to become a small to mid scale business. This claim is supported by the fact that there is only one manufacturing plant and three warehouses. And here, we also need to have the knowledge of the fact that small business major aim is to keep the cost low and satisfy the customers by making good products. So we need to suggest what information system is best suited for small scale business enterprises.

The best recommendation would be to start with a Transaction Processing System(TPS). This system will process all the day to day transactions of the system. It is like a real time system where users interact with the TPS and generate, retrieve and modify the data. This TPS would be very helpful in lowering the cost of production and at the same time manufacture and produce standard quality products . Also TPS can help in communicating with other vendors.

But TPS along would not be sufficient. Also Management Information System(MIS) would be required that can get the data from the TPS and process it to get vital information. This MIS will help in generating information regarding the sales and inventory data about the current and well as previous years. Also MIS can create many types of graphical reports which help in tactical planning of the enterprise.

So a combination of TPS as well as MIS is a minimum requirement for a Zoom Vacuum to become successful in the market.

Reggie receives a phone call from a computer user at his company who says that his computer would not turn on this morning. After asking questions, Reggie realizes that the computer seems to turn on because the user can hear fans spinning and the indicator light comes on and flashes during the boot. The Num Lock key is on, but there is no video on the monitor. Reggie also learns that the computer has a new video card. The night before the computer was working fine, according to the user. Reggie tests the video cord and the monitor. When Reggie reattaches the video cable to the video card port, the computer appears to be working. What might be the problem?

Answers

Answer:

The Integrated video may not be working properly well or functioning well.

Explanation:

Solution:

In this case, it is known that the computer was working fine a night before the problem.

If the video cable is connected to a wrong video port, then the computer was unable to work previous night.the integrated video cord has not seated because most times it occurs, due to the heat sink in the card. after restoring the video cable to the video card port, it works.

If the video was disabled in  BIOS/UEFI, it does not show video, even after restoring the cable.

A cloud provider is deploying a new SaaS product comprised of a cloud service. As part of the deployment, the cloud provider wants to publish a service level agreement (SLA) that provides an availability rating based on its estimated availability over the next 12 months. First, the cloud provider estimates that, based on historical data of the cloud environment, there is a 25% chance that the physical server hosting the cloud service will crash and that such a crash would take 2 days before the cloud service could be restored. It is further estimated that, over the course of a 12 month period, there will be various attacks on the cloud service, resulting in a total of 24 hours of downtime. Based on these estimates, what is the availability rating of the cloud service that should be published in the SLA?

Answers

Answer:

99.6

Explanation:

The cloud provider  provides the certain modules of the cloud service like infrastructure as a service , software as a service ,etc to other companies .The cloud provider implements a new SaaS service that includes a cloud platform also the cloud provider intends to disclose the Service Level Agreement that is score based on its approximate accessibility during the next 12 months.

The Cloud providers predict that, depending on past cloud system data, it is a 25 % risk that a physical server holding the cloud platform will fail therefore such a failure will require 2 days to recover the cloud service so 99.6 is the Cloud storage accessibility ranking, to be released in the SLA.

Design a program for the Hollywood Movie Rating Guide, which can be installed in a kiosk in theaters. Each theater patron enters a value from 0 to 4 indicating the number of stars that the patron awards to the Rating Guide's featured movie of the week. If a user enters a star value that does not fall in the correct range, prompt the user continuously until a correct value is entered. The program executes continuously until the theater manager enters a negative number to quit. At the end of the program, display the average star rating for the movie.

Answers

Answer:

The program in cpp is given below.

#include <iostream>

using namespace std;

int main()

{

   //variables declared to hold sum, count and average of movie ratings

   int sum=0;

   int count=0;

   int rating;

   double avg;

   //audience is prompted to enter ratings

   do{

       std::cout << "Enter the rating (0 to 4): ";

       cin>>rating;

       if(rating>4)

           std::cout << "Invalid rating. Please enter correct rating again." << std::endl;

       if(rating>=0 && rating<=4)

       {

           sum=sum+rating;

           count++;

       }

       if(rating<0)

           break;

   }while(rating>=0);

   //average rating is computed

   avg=sum/count;

   std::cout << "The average rating for the movie is " << avg << std::endl;  

   return 0;

}

OUTPUT

Enter the rating (0 to 4): 1

Enter the rating (0 to 4): 2

Enter the rating (0 to 4): 0

Enter the rating (0 to 4): 5

Invalid rating. Please enter correct rating again.

Enter the rating (0 to 4): 1

Enter the rating (0 to 4): -1

The average rating for the movie is 1

Explanation:

1. Variables are declared to hold the rating, count of rating, sum of all ratings and average of all the user entered ratings.

2. The variables for sum and count are initialized to 0.

3. Inside do-while loop, user is prompted to enter the rating for the movie.

4. In case the user enters a rating which is out of range, the user is prompted again to enter a rating anywhere from 0 to 4.

5. The loop executes until a negative number is entered.

6. Inside the loop, the running total sum of all the valid ratings is computed and the count variable is incremented by 1 for each valid rating.

7. Outside the loop, the average is computed by dividing the total rating by count of ratings.

8. The average rating is then displayed to the console.

9. The program is written in cpp due to simplicity since all the code is written inside main().

Algorithmic Complexity: what is the asymptotic complexity (Big-O) of each code section? Identify the critical section of each.\ Line 1: for (int i=0; i<532; i++) { f(n) = O( ) Line 2: for (int j=1; j

Answers

Answer:

Check the explanation

Explanation:

1) f(n) = O( 1 ), since the loops runs a constant number of times independent of any input size

there is no critical section in the code, as a critical section is some part of code which is shared by multiple threads or even processes to modify any shared variable.This code does not contain any variable which can be shared.

2) f(n) = O( log n! ), the outer loop runs for n times, and the inner loop runs log k times when i = k,ie the total number of print will be – log 1 + log2 +log3 +log4+…...+ log n = log (1 . 2 . 3 . 4 . ……. . n ) =log n!

there is no critical section in the code, as a critical section is some part of code which is shared by multiple threads or even processes to modify any shared variable.This code does not contain any variable which can be shared.

Note : Log (m *n) = Log m + Log n : this is property of logarithm

3) f(n) = [tex]O( n^2 )[/tex], since both outer and inner loop runs n times hence , the total iterations of print statement will be : n +n+n+…+n

for n times, this makes the complexity – n * n = n2

there is no critical section in the code, as a critical section is some part of code which is shared by multiple threads or even processes to modify any shared variable.This code does not contain any variable which can be shared.

Answers

Answer:

A) 22 ⅓

B) 111>18

C) There is an error in the expression

D) 25

E) 62500

Question:

Evaluate the following expressions

A) 5 + 2 * (x + 4) / 3, where x has a value of 18

B) 7/2 * 2 + 4 * (5 + 7 * 3) & gt; 18

C) 2 <= x AND x<= 7, where x has value 23

D) 50% 10 * 5 =

F) 31250/5/5 * 2 =

Explanation:

A) 5 + 2 * (x + 4) / 3

x = 18

First we would insert the value of x

5 + 2 * (x + 4) / 3

5 + 2(18 + 8) / 3

Then we would evaluate the expression by applying BODMAS : This stands for Bracket, Of, Division, Multiplication, addition and subtraction.

= 5 + 2(26) / 3

= 5 + 52/3

= 5 + 17 ⅓

= 22 ⅓

B) 7/2 * 2 + 4 * (5 + 7 * 3) > 18

we would evaluate the expression by applying BODMAS : This stands for Bracket, Of, Division, Multiplication, addition and subtraction.

7/2 * 2 + 4 * (5 + 7 * 3) >18

= 7/2 × 2 + 4× (5 + 7 × 3)>18

= (7×2)/2 + 4× (5+21) >18

= 14/2 + 4(26) >18

= 7 + 104 >18

= 111>18

C) 2 <= x AND x<= 7, where x has value 23

There is an error in the expression

D) 50% of 10 * 5

we would evaluate the expression by applying BODMAS : This stands for Bracket, Of, Division, Multiplication, addition and subtraction.

The 'of' expression means multiplication

= 50% × 10×5

= 50% × 50

50% = 50/100

=50/100 × 50

= 1/2 × 50

= 25

F) 31250/5/5 * 2

The expression has no demarcation. Depending on how it is broken up, we would arrive at different answers. Let's consider:

31250/(5/5 × 2)

Apply BODMAS

= 31250/[5/(5 × 2)]

= 31250/(5/10)

= 31250/(1/2)

Multiply by the inverse of 1/2 = 2/1

= 31250 × (2/1)

= 62500

Assume the class Student implements the Speaker interface from the textbook. Recall that this interface includes two abstract methods, speak( ) and announce(String str). A Student contains one instance data, String class Rank. Write the Student class so that it implements Speaker as follows. The speak method will output "I am a newbie here" if the Student is a "Freshman", "I like my school" if the Student is either a "Sophomore" or a "Junior", or "I can not wait to graduate" if the student is a "Senior". The announce method will output "I am a Student, here is what I have to say" followed by the String parameter on a separate line. Finally, the class Rank is initialized in the constructor. Only implement the constructor and the methods to implement the Speaker interface.

Answers

Answer:

Check the explanation

Explanation:

Based on the above information, this the following resulting code.

The solution has namely one interface named Speaker, one class called Student and one Main class called StudentMain.

The StudentMain class just initialize various instances of the Student class with various classRank values and then subsequently calling in the speak() methods of all.

announce() method is called on one such instance of Student class to demonstrate its functioning.

Comments are added at required place to better help in understanding the logic.

// Using the switch-case to code the above requirment

  public void speak() {

      switch(classRank) {

     

      case "Freshman":

          System.out.println("I am a newbie here");

          break;

      // This case would output the same result for the 2 case conditions

      case "Sophomore":

      case "Junior":

          System.out.println("I like my school");

          break;

         

      case "Senior":

          break;

      default:

          System.out.println("Unknown classRank inputted");

      }

     

  }

  //Based on the requirement, first line is printed first after second which is

  // the inputted String parameter

  public void announce(String str) {

      System.out.println("I am a Student, here is what I have to say");

      System.out.println(str);

  }

}

StudentMain.java

public class StudentMain {

 

  public static void main(String[] args) {

      Student stu1=new Student("Freshman");

      Student stu2=new Student("Sophomore");

      Student stu3=new Student("Junior");

      Student stu4=new Student("Senior");

      Student stu5=new Student("Freshman");

     

      //Calling the speak methods of the all the above create objects

      stu1.speak();

      stu2.speak();

      stu3.speak();

      stu4.speak();

      stu4.speak();

      stu4.announce("Wish u all the best");

A university wants to schedule the classrooms for final exams. The attributes are given below:
course : course id, name, and department
section : section id, enrollment, and dependent as a weak entity set on course
room : room number, capacity, and building
exam: course id, section id, room number, and time.
1) Determine the relationships among these entity sets. Clearly specify the arity, the attributes, and the mapping cardinality of these relationships.
2) Construct an E-R diagram to for the scheduling system.

Answers

Answer:

See explaination

Explanation:

Clearly the entities are as follows:-

Course

Section

Room

Test

The relationship among entities are as follows:-

Course has Section

Test is conducted for Course

Test is conducted in Section

Test is conducted in Room

Attributes of each entities are as follows:-

Course (CourseID, Name, Department)

Section (SectionID, Enrollment)

Room (RoomNumber, Capacity, Building)

Test (Time)

Section is a week entity as, there may be same sections for different courses, therefore section uses the primary key of course entity as foreign key.

Also entity Test is dependent upon the entities Room,Section and Course, therefore primary keys of these entities will be used as foreign key in the Test entity.

Write a functionvector merge(vector a, vector b)that merges two vectors, alternating elements from both vectors. If one vector isshorter than the other, then alternate as long as you can and then append the remaining elements from the longer vector. For example, if a is 1 4 9 16and b is9 7 4 9 11then merge returns the vector1 9 4 7 9 4 16 9 1118. Write a predicate function bool same_elements(vector a, vector b)that checks whether two vectors have the same elements in some order, with the same multiplicities. For example, 1 4 9 16 9 7 4 9 11 and 11 1 4 9 16 9 7 4 9 would be considered identical, but1 4 9 16 9 7 4 9 11 and 11 11 7 9 16 4 1 would not. You will probably need one or more helper functions.19.
