What is meant by ""responsive design""?

Answer:

 The TCP/IP is the transmission control protocol and internet protocol and in the TCP/IP model the transport layer is the second layer.

The primary responsibility of this layer is that it is basically used to deliver messages to the host and that is why it is known as end to end layer.

It basically provide the point to point connection between the destination to server host for delivering the various types of the services efficiently and reliably.

In the TCP/IP model the transport layer are basically responsible for transferring the data or service error free between the server to destination host.

Answer:

By definition a foreign key of table A is a primary key of another table B, thereby establishing a link between them.

To provide referential integrity you can use these referential actions:

Answer: Decision support system (DSS)

Explanation:

 Decision support system is the process in which the information model basically support the managers in the process of the decision making.

It is an information system and produces various reports and also interprets the data and information so that it help to make decisions.

The decision support system (DSS) is basically carried out by the management by reviewing all kinds of the report and then generate necessary data or information.

On the other hand, all the other options are incorrect as they are not related to the decision making process. Therefore, DSS is the correct option.

Answer:

// here is code in C.

#include <stdio.h>

int main(void) {

int num;

 // loop run 100 times

for(num=1;num<=100;num++)

{

 //check divisibility by 3 and 5

    if(num%15==0)

    {

    printf("fizz buzz ");

    }

     // check divisibility by 5 only

    else if(num%5==0)

    {

        printf("buzz ");

    }

     // check divisibility by 3 only

    else if(num%3==0)

    {

        printf("fizz ");

    }

    else{

        printf("%d ",num);

    }

}

return 0;

}

Explanation:

Run a for loop from 1 to 100. Check the divisibility of number by 15, if it is divisible print "fizz buzz", if it is not then Check the divisibility by 5 only.if it returns true then print "buzz". if not then check for 3 only,if returns true, print "fizz". else print the number only.

Output:

1 2 fizz 4 buzz fizz ........buzz fizz 97 98 fizz buzz

Answer: peer-to-peer (P2P) file sharing

Explanation: Peer-to-peer file sharing is the technique in which networking technology is used for the sharing and distribution of the files digitally. The sharing of the files are in the form of movies, games music etc.

Peer are considered as the nodes which are the end-user so, the end-user to end-user file transfer is done through this technology.

Other options are incorrect because VPN(virtual private network) is the connection between network and client over less secure network,LAN (Local area network) is the network that can be established for single infrastructure to connect  and point to point protocol is protocol for the routers for communication.Thus the correct option is P2P file sharing.

Answer:

Data mining is the extraction/mining of the required/ actual data from the raw data .Rest of the data that is not required is eliminated in this process.It is used in the many field such as research, scientific, etc.

Robustness in the data mining field is for defining the strong nature of the data .This feature is responsible for stability of the data even at the occurrence of the error.The resistance shown by the data towards the problem makes the data robust .

The synchronization helps in updating the information or data that is present in both the devices .It also sends and receive the files and information from reach other through transferring activity.The act helps in keeping the same updated information in both the system.

Answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

   // variable

   double height;

   // gravitational acceleration

   double g=9.8;

   cout<<"Please enter initial height:";

   cin>>height;

   // h=ut+(gt^2)/2

   // here u, initial velocity is 0

   // after simplification

   double t=sqrt(2*height/g);

   // print the time

   cout<<"time taken by ball to hit the ground is:"<<t<<" seconds"<<endl;

return 0;

}

Explanation:

Read the initial height from user. Declare and initialize the earth gravitational acceleration "g=9.8" .Then the equation is h=ut+(gt^2)/2, here u is initial velocity which is 0.Then after simplify the equation t=sqrt(2*h/g). Put the values in the  equation and find the time taken by ball to hit the ground.

Output:

Please enter initial height:100

time taken by ball to hit the ground is:4.51754 seconds

Final answer:

A Python program calculates the time a ball takes to reach the ground when dropped from a given height, illustrating basic principles of free fall in physics. For a 100 m tower, the time is approximately 4.51 seconds.

Explanation:

A student has asked to write a program that computes the time it takes for a ball to hit the ground when dropped from a tower of height h meters, assuming no air resistance. The formula to calculate the time t is derived from physics: t = √(2h/g), where g is the acceleration due to gravity, approximately 9.81 m/s². Using this formula, we candevelop a program in Python to ask the user for the height h and then compute and print the time t. To demonstrate, if the program is used with a tower height of 100 meters, the calculated time for the ball to reach the ground would be approximately 4.51 seconds.

Example Python Program

import math

def drop_time_from_height(height):
   g = 9.81  # Gravity in m/s²
   time = math.sqrt(2 * height / g)
   return time

height = float(input("Enter the height of the tower in meters: "))
time = drop_time_from_height(height)
print("The ball takes", round(time, 2), "seconds to hit the ground.")

This program illustrates a straightforward approach to solving problems related to free fall and physics calculations, enhancing the understanding of concepts such as gravity and acceleration.

Explanation:

Pros:

Cons:

Answer:

Always available to run: You can run the tests 24/7, when you are at work, when you leave the office or if you working remote, you can run the test. They can be run virtually unattended, leaving the results to be monitored towards the end of the process.

Fewer human resources: You can reduce the people advocated on testing, you would need a QA automation to write your scripts to automate your tests, instead of people doing manual tests. In addition, once automated, the test library execution is faster and runs longer than manual testing.

Reusability and reliability: The scripts are reusable, a script could be used hundreds of times before need changes. It allows you to test exactly the same, without forgetting any steps this is why is more reliable and way quicker than manual test where people may cause.

Answer: Character reference is the tool usually followed in the business world.It is defined as the recommendation that is provided by organization employee that has a relation with the candidate(individual) outside of the work. This also known as the personal reference. The candidate can be friend family or any other known person whose reference is being given.

This is used in the business field for revealing about the personality and character of the candidate apart from the skills and working abilities. It also helps in the hiring of the candidate easily when the description is good in the character reference.

Answer: Only A and C

Explanation: Default constructor is a constructor that has parameters with the values that are default or has no arguments/parameter present. Default constructor is not declared in the class rather it gets generated by itself when not defined.

Class is defined with data members, functions, objects etc are considered as per the requirement given by the user .It is the user defined concept.

Statement (B) is incorrect because static method is used for accessing the static members of the particular class and manipulate the value of it.

Thus, only statement (A) and (C) are correct.

Final answer:

A simple Python program prompts the user to enter personal information such as name, address, phone number, and email, then displays it back. It's essential to handle personal data responsibly and to check privacy policies in real applications.

Explanation:

The question is asking for a simple program that collects and displays personal information. Here is an example of how such a program can be written in Python:

# Ask for personal information
name = input('Please enter your name: ')
address = input('Please enter your address: ')
phone_number = input('Please enter your phone number: ')
email = input('Please enter your email: ')

# Display the information back to the user
print('\nHere is the information you entered:')
print('Name:', name)
print('Address:', address)
print('Phone Number:', phone_number)
print('Email:', email)

This program will prompt the user to enter their name, address, phone number, and email. It will then display this information back to the user. Remember to handle personal information responsibly and refer to privacy policies when handling such data in real applications.

False

The difference between RAM and RAM is as follows

(1) RAM (random access memory) is meant for temporary storage whereas ROM (read-only memory) is meant for permanent storage.

(2) RAM chip is volatile, means once the power is turned off, it loses the previously holding information, where as ROM is non-volatile it doesn't losses any information even though power is turned off.

(3) RAM chip is used in the normal operations of the computer, whereas the ROM chip is used mainly for the startup process of computer.

(4) Generally, A RAM can store several gigabytes (GB) of data that is up to 16 GB whereas a ROM chip can typically store that much data. It only stores several megabytes (MB) of data that is up to 4 MB.

hence, the given statement about RAM is false.

Answer:

void reverse(char dest[], char source[], int size)

{

   for(int i=0;i<size;i++)//using for loop.

   {

       dest[i]=source[i];//assigning each element of source array to dest array.

   }

   int s=0,e=size-1;//initializing two elements s with 0 and e with size -1.

   while(s<e){

       char t=des[s];             //SWAPPING

       dest[s]=dest[e];            //SWAPPING

       dest[e]=t;                  //SWAPPING

       s++;

       e--;

   }

}

Explanation:

I have used while loop to reverse the array.I have initialize two integer variables s and e with 0 and size-1.Looping until s becomes greater than e.

It will work as follows:

first s=0 and e=0.

dest[0] will be swapped with dest[size-1]

then s=1 and e=size-2.

then des[1] will be swapped with dest[size-2]

and it will keep on going till s is less than e.

Answer:

The answer to the questions: Does Kennesaw State University have any computing ethical policy for computer usage? If so - what is it? Would be as follows:

1. Yes, Kennesaw State University, a university in Georgia, does have a computing ethical policy that regulates the proper use of the facilities and computing services within the facilities of the university and the use of computing equipment that belongs to the university. This policy is known as the KSU Computer Usage Policy.

2. As said before this policy establishes that the use of computing services are not the right of a person, but rather a privilege afforded to the students, faculty and other people who are present in the university and who may need to use its computing services. The use of the computing services would be whitin this policy as long as it stays inside the delimitations established by federal, state and University policies.

Explanation:

Answer:

The list created by the split method in Python 3 will be ["red", "orange", ""yellow", "green", "blue"]

Explanation:

In Python 3, the split method takes the input string, in this case is colors = "red,orange,yellow,green,blue", and split it into a list and you can indicate the separator that the method will use.

The general syntax for this method is:

string.split(separator,max)

separator indicates the character that will be used as a delimiter of each list member and the max parameter indicates the maximum number of separations to make.  

Since each color in your string is separated by the character "," the code will make a list in which every color is a separated string.

Answer:

string objects are cached in string pool.

Explanation:

Strings in Java are immutable or final because the string objects are cached in String Pool.As we know multiple clients share the string literals so there exists a risk of one client's action affecting all other clients.

For ex:-The value of string is "Roast" and client changed it to "ROAST" so all other clients will see ROAST instead of Roast.

Answer:

// here is code in java.

// import package

import java.util.*;

// class definition

class Main

{

   // main method of the class

public static void main (String[] args) throws java.lang.Exception

{

   try{

      // print the name

       System.out.print("my name is Sam. ");

       // print the major

       System.out.print("my major is CS.");

   }catch(Exception ex){

       return;}

}

}

Explanation:

In java, System.out.print() will print the statement but didn't go to the next line.If there is another System.out.print(), then it will also print into the same line.So here first the System.out.print() will print the name and second will print the major in the same line.

Output:

my name is Sam. my major is CS.

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

// variables

  int minn=INT_MAX;

   int maxx=INT_MIN;

   int n1,n2,n3,n4,n5;

   cout<<"enter five Numbers:";

   //read 5 Numbers

   cin>>n1>>n2>>n3>>n4>>n5;

   // find maximum

   if(n1>maxx)

    maxx=n1;

    if(n2>maxx)

    maxx=n2;

    if(n3>maxx)

    maxx=n3;

    if(n4>maxx)

    maxx=n4;

    if(n5>maxx)

    maxx=n5;

   // find minimum

   if(n1<minn)

    minn=n1;

    if(n2<minn)

    minn=n2;

    if(n3<minn)

    minn=n3;

    if(n4<minn)

    minn=n4;

    if(n5<minn)

    minn=n5;

   // print maximum and minimum

   cout<<"maximum of five numbers is: "<<maxx<<endl;

   cout<<"minimum of five numbers is: "<<minn<<endl;

return 0;

}

Explanation:

Declare two variables "minn" & "maxx" and initialize them with INT_MAX and INT_MIN respectively.Then read the five number from user and compare it with "minn" & "maxx" ,if input is greater than "maxx" then update "maxx" or if input is less than "minn" then update the "minn". After all the inputs, "minn" will have smallest and "maxx" will have largest value.

enter five Numbers:5 78 43 55 12

maximum of five numbers is: 78

minimum of five numbers is: 5
