2: The internet is a fast, easy and effeciant way to communicate. other reasons may be for banking purposes, online grocery shopping, etc.
3 & 4: Self answerable questions.
5: Common communication nowadays is texting, phone calls, etc. It's easier to press a button or two to send out information than what it used to be. For example, it often took days, weeks, and even months for messages to be sent from one location to a far-flung position.
6: ( MY OPINION ) I feel like the internet is (in a lot of ways) bad for the younger generation and the ( soon to come ). There are alot of online predators, blogs/websites that have inappropriate content. It's quite easy for a teen to just go to a po**ographic site nowadays, type in his/her email and just simply watch it like that. Some of them don't require sign up to view videos, images, gifs. And about the online predator situation, a lot of teenagers (girls AND boys) often feel pressured into sending images of themselves now.

Vector testGrades contains NUM_VALS test scores. Write a for loop that sets sumExtra to the total extra credit received. Full credit is 100, so anything over 100 is extra credit. Ex: If testGrades = {101, 83, 107, 90}, then sumExtra = 8, because 1 + 0 + 7 + 0 is 8.
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;
Explanation:
Using Python code.
Fill in the gaps in the nametag function so that it uses the format method to return first_name and the first initial of last_name followed by a period. For example, nametag("Jane", "Smith") should return "Jane S."
def nametag(first_name, last_name):
return("___.".format(___))
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."
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.

"If someone really wants to get at the information, it is not difficult if they can gain physical access to the computer or hard drive." - Microsoft White Paper, July 1999. Is this statement categorically true or just true in most cases
Answer:
It is just true in most cases
Explanation:
This statement is just true in most cases because in some cases having a physical access to the computer or hard drive this does not guarantee access to the information contained in the hard drive or computer because the data/information in the hard drive or computer might as well be encrypted and would require a password in order to de-crypt the information.
Having a physical access is one step closer in some cases but not the only step required .

Error messages are a key part of an overall interface design strategy of guidance for the user. Discuss strategies to ensure integrated, coordinated error messages that are consistent across an application.
Answer:
Answered below
Explanation:
In order to not discourage the user, error messages must be implemented in a user-friendly way with the use of strategies which ensure coordination, consistency and simplicity.
Error messages should be short, direct and communicate clearly, the right amount of information to a user. These messages should be sorted into categories which represent different kinds of errors. These specific categories should have a brief alphanumeric code that can be easily shared with a customer support personnel for solution and also to help users search for solutions themselves, on the internet.
The balanced F measure (a.k.a. F1) is defined as the harmonic mean of precision and recall. What is the advantage of using the harmonic mean rather than "averaging" (using the arithmetic mean)?
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

#We've started a recursive function below called #measure_string that should take in one string parameter, #myStr, and returns its length. However, you may not use #Python's built-in len function. # #Finish our code. We are missing the base case and the #recursive call. # #HINT: Often when we have recursion involving strings, we #want to break down the string to be in its simplest form. #Think about how you could splice a string little by little. #Then think about what your base case might be - what is #the most basic, minimal string you can have in python? # #Hint 2: How can you establish the base case has been #reached without the len() function? #You may not use the built-in 'len()' function.
Answer:
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

In C++
Answer:
The program written in C++ is as follows
#include<iostream>
using namespace std;
int main(){
string lname, fname;
cout<<"First name: ";
cin>>fname;
cout<<"Last name: ";
cin>>lname;
cout<<lname<<", "<<fname;
return 0;
}
Explanation:
This line declares lname, fname as string to get the user's last name and first name, respectively
string lname, fname;
This line prompts the user for first name
cout<<"First name: ";
This line gets the user first name
cin>>fname;
This line prompts the user for last name
cout<<"Last name: ";
This line gets the user last name
cin>>lname;
This line prints the desired output
cout<<lname<<", "<<fname;
The program in Python is
person_name = input("Enter your first name and last name separated
by space: ")
split_names = person_name.split( )
first_name = split_names[0]
last_name = split_names[1]
print(last_name + ", " + first_name)
The first line of the program requests the first and last names as a single string, separated by a space.
The next line splits the name into first and last names
Finally, the print statement displays the names reversed, but separated with a comma

The figure below shows a black and white image with a resolution of 720×504. Identify how much memory (in bits) will be occupied by this image in the hard drive of your computer, if it is stored. (2 marks)
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.

Write a copy assignment operator for CarCounter that assigns objToCopy.carCount to the new objects's carCount, then returns *this. Sample output for the given program:
Answer:
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
Write a program to complete the task given below: Ask the user to enter any 2 numbers in between 1-10 and add both of them to another variable call z. Use z for adding 30 into it and print the final result by using variable results.
Answer:
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.

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
Java provides a number of interfaces and classes to systematically implement collections.
a. True
b. False
Answer:
A) True
Explanation:
Java provides collections architecture or framework used to store and manipulate a group of objects or collections.
The collection framework has interfaces which include; Set, Queue, Deque, List, as well as classes which include; Hashset, ArrayList, LinkedList, LinkedHashset, PriorityQueue, Vector and TreeSet.
There are also many methods declared in the collection interface which include; add(), addAll(), remove(), removeAll(),retainAll(), clear(), size(), iterator(), toArray() etc
How SDN is different from a normal network setup?
Answer:
I hope this is right (one difference)
SDN is software based whereas normal network setup is mostly hardware based
Pls ask me if you want another differrence! :)

Referential integrity constraints are concerned with checking INSERT and UPDATE operations that affect the parent child relationships.
a) true
b) false
Answer:
a) true
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;
Key constraints. Domain constraints. Entity integrity constraints. Referential integrity constraints.
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.
