Suppose your network support company employs 75 technicians who travel constantly and work at customer sites. Your task is to design an information system that provides technical data and information to the field team. What types of output and information delivery would you suggest for the system?

Answer:

No, it is not the final step in decision-making model. It is rather the penultimate stage of the model of decision making.

Explanation:

The final step of the decision-making model is reviewing your decision and its consequences. The decision-making model has total of 7 steps. One should follow these all the steps to make it error free and more efficient then it rather would have been when the decision was made without following it.

The very first step of this model is to identify the decision. And it is one of the most important steps to be followed to avoid any error.  

Answer:

The sequence of events in processing information, which includes:

1) input

2) processing

3) storage and

4) output.

These processes work together and repeat over and over. Input—entering data into the computer. Processing—performing operations on the data.

Explanation:

1. Input: The computer receives data from a user or software. A keyboard, microphone, or other input device can be used as a user's input source.

2. Processing: The computer processes data after it has been received by performing logical comparisons or mathematical calculations as instructed by the user or a program.

3. Output: After processing, data is delivered as output. The speaker, printer, monitor, or other output devices display the output results.

4. Storage: The processed data can be saved by the computer to a storage device for later use.

Answer:

D) GUI

Explanation:

GUI an acronym for Graphical user interface, is a type of user interface where a user interacts with a computer or an electronic device through the use of graphics. These graphics include icons, images, navigation bars etc.

GUIs use a combination of technologies and devices to create a layout that users can interact with and perform tasks on. This makes it easier for users who do have basic computer skills to utilize.

The most common combination of these elements is the windows, icons, menus and pointer paradigm (WIMP) . GUIs are used in mobile devices, gaming devices, smartphones, MP3 players etc.

Answer:

362880

Explanation:

In black and white images each pixel is 1 bit. You need to first find the total number of pixels, to do this you multiply the width and length of the picture (720x504) and you will get 362880. From there you would multiply the amount of pixels by how many bits each pixel is. In this case, since its black and white you multiply it by 1, which is 362880.

Answer:

Here are the programs. I am writing C++ and Python programs:

a)

C++

#include<iostream>   

using namespace std;    

int factorial(int number)  {  

   if (number == 0)  

       return 1;  

   return number * factorial(number - 1);  }    

int main()  {  

   int integer;

   cout<<"Enter a non negative integer: ";

   cin>>integer;

   cout<< "Factorial of "<< integer<<" is "<< factorial(integer)<< endl;  }

Python:

def factorial(number):  

   if number == 0:  

       return 1

   return number * factorial(number-1)  

integer = int(input("Enter a non negative integer: "))  

print("Factorial of", integer, "is", factorial(integer))

b)

C++

#include <iostream>  

using namespace std;

double factorial(int number) {  

if (number == 0)  

 return 1;  

return number * factorial(number - 1); }  

double estimate_e(int num){

    double e = 1;

    for(int i = 1; i < num; i++)

     e = e + 1/factorial(i);

     cout<<"e: "<< e; }  

int main(){

int term;

cout<<"Enter a term to evaluate: ";

cin>>term;

estimate_e(term);}

Python:

def factorial(number):  

   if number == 0:  

       return 1

   return number * factorial(number-1)  

def estimate_e(term):

   if not term:

       return 0

   else:

       return (1 / factorial(term-1)) + estimate_e(term-1)

number = int(input("Enter how many terms to evaluate "))

print("e: ", estimate_e(number))

c)

C++

#include <iostream>

using namespace std;

int main(){

   float terms, sumSeries, series;

   int i, number;

   cout << " Input the value of x: ";

   cin >> number;

   cout << " Input number of terms: ";

   cin >> terms;

   sumSeries = 1;

   series = 1;

   for (i = 1; i < terms; i++)      {

       series = series * number / (float)i;

       sumSeries = sumSeries + series;     }

   cout << " The sum  is : " << sumSeries << endl;  }  

Python    

def ePowerx(number,terms):

   sumSeries = 1

   series =1

   for x in range(1,terms):

       series = series * number / x;

       sumSeries = sumSeries + series;

   return sumSeries    

num = int(input("Enter a number: "))

term=int(input("Enter a number: "))

print("e^x: ",ePowerx(num,term))

Explanation:

a)

The program has a method factorial that takes numbers as parameter and computes the factorial of that number by using recursion. For example if the number = 3

The base case is  if (number == 0)

and

recursive is return number * factorial(number - 1);    

Since number = 3 is not equal to zero so the method calls itself recursively in order to return the factorial of 3

return 3* factorial(3- 1);

3 * factorial(2)

3* [2* factorial(2- 1) ]

3 * 2* [ factorial(1)]

3 * 2 * [1* factorial(1- 1) ]

3 * 2 * 1* [factorial(0)]

Now at factorial(0) the base condition is reached as number==0 So factorial(0) returns 1

Now the output is:

3 * 2 * 1* 1

return 6

So the output of this program is

Factorial of 3 is 6

b)

The method estimate_e takes a number i.e. num as parameter which represents the term and estimates the value of the mathematical constant e

The for loop iterates through each term. For example num = 3

then  

e = e + 1/factorial(i);  

The above statement calls works as:

e = 1 + 1/1! +1/2!

since the number of terms is 3

e is initialized to 1

i  is initialized to 1

So the statement becomes:

e = 1 + 1/factorial(1)

factorial function is called which returns 1 since factorial of 1 is 1 So,

e = 1 + 1/1

e = 2

Now at next iteration at i = 2 and e = 2

e = 2 + 1/factorial(2)

e = 2 + 1/2

e = 2.5

Now at next iteration at i = 3 and e =3

e = 3 + 1/factorial(3)

e = 3 + 1/6

e = 3.16666

So the output is:

e: 3.16666

c)

The program computes the sum of series using formula:

e^x = 1 + x/1! + x^2/2! + x^3/3! +...

The for loop iterates till the number of terms. Lets say in the above formula x is 2 and number of terms is 3. So the series become:

e^x = 1 + x/1! + x^2/2!

So number = 2

terms = 3

series =1

sumSeries = 1

i = 1

The statement series = series * number / (float)i; works as following:

series = 1 * 2 /1

series = 2

sumSeries = sumSeries + series;

sumSeries = 1 + 2

sumSeries = 3

At next iteration: i=2, series =2 , sumSeries =3

series = 2 * 2/2

series = 2

sumSeries = 3 + 2

sumSeries = 5

Now the loop breaks as i=3

So output returns the value of sumSeries i.e. 5

Output:

e^x: 5

Answer:

Because the value derived from harmonic mean reflects the credible result of search engine

Explanation:

Given that the value of arithmetic mean tends to be closer to the highest value between Precision and Recall, while the value of the harmonic mean, is the lowest value between Precision and Recall, in a situation where all documents relevant to a query are returned, where R = 1 and P is closer to 0, the arithmetic mean will be greater than 0.5 and will not reflects the credible result of search engine

However, if the harmonic mean is utilized, the value will be closer to the low Precision value, hence it closely reflects the credible result of search engine

Answer:

def nametag(first_name, last_name):

return("{} {[0]}.".format(first_name, last_name))

print(nametag("Jane", "Smith"))

# Should display "Jane S."

print(nametag("Francesco", "Rinaldi"))

# Should display "Francesco R."

print(nametag("Jean-Luc", "Grand-Pierre"))

# Should display "Jean-Luc G."

Explanation:

First you must think about that the question ask about the first letter for last_name, remember [0] is the first letter not [1], the other part is about format function and its order

The format method to return first_name and the first initial of last_name followed by a period in python is represented as follows:

def nametag(first_name, last_name):

  return '{} {}.'.format(first_name, last_name[0])

print(nametag("Jane", "Smith"))

print(nametag("Francesco", "Rinaldi"))

print(nametag("Jean-Luc", "Grand-Pierre"))

A function named nametag is declared with the arguments first_name and last_name.

Then it returns the first name and the initial of the last_name using the .format method.

Then we call the function using the print statement with the arguments.

Explanation:

In Computer programming, integrity constraints can be defined as a set of standard rules that ensures quality information and database are maintained.

Basically, there are four (4) types of integrity constraints and these are;

1. Key constraints.

2. Domain constraints.

3. Entity integrity constraints.

4. Referential integrity constraints.

Referential integrity is a property of data which states that each foreign key value must match a primary key value in another relation or the foreign key value must be null.

For instance, when a foreign key in Table A points to the primary key of Table B, according to the referential integrity constraints, all the value of the foreign key in Table A must be null or match the primary key in Table B.

Hence, the referential Integrity constraints ensures that the relationship between the data in a table is consistent and valid.

Hence, referential integrity constraints are concerned with checking INSERT and UPDATE operations that affect the parent child relationships.

This ultimately implies that, referential Integrity are rules used in database management systems (DBMS) to ensure relationships between tables when records are changed is VALID (INSERT and UPDATE).

In a nutshell, it always ensures a primary key must have a matching foreign key or it becomes null.

In this exercise we have to analyze the integrity that some constraints have, so the alternative that best matches is;

True

In Computer plan out, uprightness constraints maybe delineate as a set of standard rules that guarantee kind information and collection of data happen uphold. Basically, skilled are four (4) types of completeness restraint and these exist;

Referential honor exist a property of information in visible form that states that each irrelevant key value must equal a basic key profit in another family connection or the from another country key profit must be ineffectual.

For instance, when a experience transfer data from one computer system to another Table A points to the basic key of Table B, in accordance with the referential purity restraint, all the worth of the from another country transfer data from one computer system to another Table A must exist valueless or counterpart the basic transfer data from one computer system to another Table B.

Hence, the referential Integrity restraint make secure that the relationship middle from two points the information in visible form in a table exist compatible and right. Hence, referential integrity restraint exist concerned with restrain INSERT and UPDATE movement that influence the parent very young person connection.

This eventually indicate that, referential Integrity are rules secondhand fashionable collection of data management structure (DBMS) to make secure friendship middle from two points tables when records are transformed exist VALID (INSERT and UPDATE). In a nutshell, it forever ensures a basic key must bear a equal foreign key or it enhance ineffectual.

a = int(input("Enter first value between 1 - 10"))

b = int(input("Enter second value between 1 - 10"))

z = a + b

z += 30

print("The value of z = ", z)

Explanation:

The code is written above in python language to perform the given task.

Now, let us explain each statement of code.

Step 1: The first two lines take input from the user prompting the user to enter the values between 1 to 10.

Then the values are type casted to int using int().

The values are stored in variables a and b.

Step 2: Then, the values of a and b are added to get another variable z.

Step 3: The statement 'z += 30' is equivalent to z = z+30

It adds 30 to the variable z and stores it in the same variable z.

Step 4: Finally the value of variable 'z' is printed using print() command.

Answer:

Here is for loop that sets sumExtra to the total extra credit received. I am writing a program in C++

for(i = 0; i <= testGrades.size() - 1; i++){

  if(testGrades.at(i) > 100){

      sumExtra = sumExtra + (testGrades.at(i) - 100);   } }

Explanation:

The complete program is:

#include <iostream> //to use input output functions

#include <vector> //to use vectors

using namespace std; //to identify objects like cin cout

int main() { //start of main function

const int NUM_VALS = 4; // sets the value of NUM_VALS as a constant to 4

vector<int> testGrades(NUM_VALS); // initialize the vector of int (integer) type

int i = 0; // i is initialzed to 0

int sumExtra = 0; //stores the total extra credit

testGrades.at(0) = 101; //sets 101 at first position in vector

testGrades.at(1) = 83; //sets value 83 at second position

testGrades.at(2) = 107; //sets value 107 at third position

testGrades.at(3) = 90; //sets value 90 at fourth position

for(i = 0; i <= testGrades.size() -1; i++){ //loop iterate through each value of in a vector testGrades

  if(testGrades.at(i) > 100){ // if the value in a vector exceeds 100

      sumExtra = sumExtra + (testGrades.at(i) - 100);   } } //computes total extra credit

cout << "sumExtra: " << sumExtra << endl;} //displays the value of computed total extra credit in output

The loop works as follows:

In the first iteration the value of vector testGrades at(i) is at(0) = 101.

if statement checks if this value/element is greater than 100. This is true as 101 > 100. So sumExtra = sumExtra + (testGrades.at(i) - 100); statement is executed in which 100 is subtracted from that element and the result is added to the sumExtra. sumExtra is initialized to 0 so the value of sumExtra becomes: 0+ 101 - 100= 1 So the value of sumExtra = 1

In the second iteration the value of i = 1 and it is positioned at 2nd value of vector testGrades i.e. 83. Then if statement checks if this value/element is greater than 100. This is false as 83 < 100. So the value of sumExtra = 1

In the third iteration the value of i = 2 and it is positioned at 3rd value of vector testGrades i.e. 107. Then if statement checks if this value/element is greater than 100. This is true as 107 > 100.

sumExtra = sumExtra + (testGrades.at(i) - 100); statement is executed in which 100 is subtracted from that element and the result is added to the sumExtra

sumExtra is 1 so the value of sumExtra becomes: 1+ 107 - 100= 8 So the value of sumExtra = 8

In fourth iteration  the value of i = 3 and it is positioned at 4th value of testGrades vector i.e. 90. Then the if statement checks if this element is greater than 100. This is false as 90 < 100. So the value of sumExtra remains 8.  

Finally the loop breaks as the value of i becomes 4. So the output is 8.

Answer:

sumExtra = 0;

   for (i = 0; i < NUM_VALS; ++i) {

     if (testGrades[i] >= 101) {

     sumExtra += (testGrades[i] - 100);

     }

   }

   cout << "sumExtra: " << sumExtra << endl;

Here is the copy assignment operator for CarCounter:

CarCounter& CarCounter::operator=(const CarCounter& objToCopy) {

carCount = objToCopy.carCount;

return *this;  }

The syntax for copy assignment operator is:

ClassName& ClassName :: operator= ( ClassName& object_name)

In the above chunk of code class name Is CarCounter and object name is objToCopy.

Assignment operator = is called which assigns objToCopy.carCount to the new objects's carCount.

This operator basically is called when an object which is already initialized is assigned a new value from another current object.

Then return *this returns the reference to the calling object

Explanation:

The complete program is:

#include <iostream>  //to use input output functions

using namespace std;   //to access objects like cin cout

class CarCounter {  //class name

public:  // public member functions of class CarCounter

CarCounter();  //constructor of CarCounter

CarCounter& operator=(const CarCounter& objToCopy);  //copy assignment operator for CarCounter

void SetCarCount(const int setVal) {  //mutator method to set the car count value

carCount = setVal;  } //set carCount so setVal

int GetCarCount() const {  //accessor method to get carCount

return carCount;  }  

private:  //private data member of class

int carCount;  };    // private data field of CarCounter

CarCounter::CarCounter() {  //constructor

carCount = 0;  //intializes the value of carCount in constructor

return; }  

// FIXME write copy assignment operator  

CarCounter& CarCounter::operator=(const CarCounter& objToCopy){

/* copy assignment operator for CarCounter that assigns objToCopy.carCount to the new objects's carCount, then returns *this */

carCount = objToCopy.carCount;

return *this;}  

int main() {  //start of main() function

CarCounter frontParkingLot;  // creates CarCounter object

CarCounter backParkingLot;   // creates CarCounter object

frontParkingLot.SetCarCount(12);  // calls SetCarCount method using object frontParkingLot to set the value of carCount to 12

backParkingLot = frontParkingLot;  //assigns value of frontParkingLot to backParkingLot

cout << "Cars counted: " << backParkingLot.GetCarCount();  //calls accessor GetCarCount method to get the value of carCount and display it in output

return 0;  }

The output of this program is:

Cars counted = 12

Here is the Python program:

def measure_string(myStr):  #function that takes a string as parameter

   if myStr == '':  #if the string is empty (base case)

       return 0  #return 0

   else:  #if string is not empty

       return 1 + measure_string(myStr[0:-1])  #calls function recursively to find the length of the string (recursive case)

#in order to check the working of the above function the following statement is used        

print(measure_string("13 characters")) //calls function and passes the string to it and print the output on the screen        

Explanation:

The function works as following:

Suppose the string is 13 characters

myStr = "13 characters"

if myStr == '': this is the base case and this does not evaluate to true because myStr is not empty. This is basically the alternate of

if len(myStr) == 0: but we are not supposed to use len function here so we use if myStr == '' instead.

So the program control moves to the else part

return 1 + measure_string(myStr[0:-1])  this statement is a recursive call to the function measure_string.

myStr[0:-1] in the statement is a slice list that starts from the first character of the myStr string (at 0 index) to the last character of the string (-1 index)

This statement can also be written as:

return 1 + measure_string(myStr[1:])

or

return 1 + measure_string(myStr[:-1])  This statement start from 1st character and ends at last character

This statement keeps calling measure_string until the myStr is empty. The method gets each character using a slice and maintains a count by adding 1 each time this statement is returned.The function breaks string into its first character [0:] and all the rest characters [:-1]. and recursively counts the number of character occurrences and add 1. So there are 13 characters in the example string. So the output is:

13
