Answer:
The correct statement regarding DCE and DTE interfaces is:
c. DTE and DCE describes the interface and direction of data flow between devices; a single device may have both types of interfaces.
Explanation:
DTE stands for Data Terminal Equipment. It is a device that initiates or controls a device's serial connection. The term DCE stands for Data Communications Equipment. It is a device that is used to a modem or other communication interfaces to the DTE device. DTE is a communication receptor, while DCE is a communication broadcaster or distributor.
3. When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested?
A. Series
B. Parallel
C. Control
D. Line
Answer:
B. Parallel
Explanation:
When using the ohmmeter function of a digital multimeter, the leads are placed parallel to the component being tested. The digital multimeter is placed parallel to the component because, current has to flow into the component so as to be able to measure its resistance. Without the flow of current in the component, the resistance could not be measured.
If the component were placed in series, there would be no way to close the circuit because, we need a closed circuit so as to measure the resistance and use the ohmmeter function of the digital multimeter.
Only a parallel connection would close the circuit.
So, B is the answer.
Write a Python program square_root.py that asks a user for an integer n greater or equal to 1. The program should then print the square root of all the odd numbers between 1 and n (Including n if n is odd). Print the square roots rounded up with no more than two digits after the decimal point.
Answer:
import math
n = int(input("Enter n: "))
for number in range(1, n+1):
if number % 2 == 1:
print("{:.2f}".format(math.sqrt(number)), end=" ")
Explanation:
In order to calculate the square roots of the numbers, import math. Note that math.sqrt() calculates and gives the square root of the given number as a parameter
Ask the user to enter the n
Create a for loop that iterates from 1 to n+1 (Since n is included, you need to write n+1)
Inside the loop, check whether the number is odd or not using the if structure and modulo. If the number is odd, calculate its square root using the math.sqrt() and print the result with two digits after the decimal

Answer:
Explanation:
The code provided worked for the most part, it had some gramatical errors in when printing out the information as well as repeated values. I fixed and reorganized the printed information so that it is well formatted. The only thing that was missing from the code was the input validation to make sure that no negative values were passed. I added this within the getMonths() method so that it repeats the question until the user inputs a valid value. The program was tested and the output can be seen in the attached image below.

Following are the code to the given question:
#include <iostream>//defining header file
#include <vector>//defining header file
#include <numeric>//defining header file
using namespace std;
int main()//main method
{
vector<int> countDown(0);//defing an integer array variable countDown
int newSize = 0;//defing an integer variable newSize that holds a value 0
int i = 0;//defing an integer variable i that initialize with 0
newSize = 3;// //use newSize to hold a value
countDown.resize(newSize,0);// calling the resize method that accepts two parameters
for (i = 0; i < newSize; ++i)//defining a loop that reverse the integer value
{
countDown[i] = newSize -i;//reverse the value and store it into countDown array

Preserving confidentiality, integrity, and availability is a restatement of the concern over interruption, interception, modification, and fabrication.
i. Briefly explain the 4 attacks: interruption, interception, modification, and fabrication.
ii. How do the first three security concepts relate to these four attacks
Answer and Explanation:
I and II answered
Interruption: interruption occurs when network is tampered with or communication between systems in a network is obstructed for illegitimate purposes.
Interception: interception occurs when data sent between systems is intercepted such that the message sent to another system is seen by an unauthorized user before it reaches destination. Interception violates confidentiality of a message.
Modification: modification occurs when data sent from a system to another system on the network is altered by an authorized user before it reaches it's destination. Modification attacks violate integrity, confidentiality and authenticity of a message.
Fabrication: fabrication occurs when an unauthorized user poses as a valid user and sends a fake message to a system in the network. Fabrication violates confidentiality, integrity and authenticity.
Write a program that reads a list of integers, and outputs those integers in reverse. The input begins with an integer indicating the number of integers that follow. For coding simplicity, follow each output integer by a comma, including the last one.Ex: If the input is:5 2 4 6 8 10the output is:10,8,6,4,2,To achieve the above, first read the integers into a vector. Then output the vector in reverse.
Answer:
The program in C++ is as follows:
#include <iostream>
#include <vector>
using namespace std;
int main(){
vector<int> intVect;
int n;
cin>>n;
int intInp;
for (int i = 0; i < n; i++) {
cin >> intInp;
intVect.push_back(intInp); }
for (int i = n-1; i >=0; i--) { cout << intVect[i] << " "; }
return 0;
}
Explanation:
This declares the vector
vector<int> intVect;
This declares n as integer; which represents the number of inputs
int n;
This gets input for n
cin>>n;
This declares intInp as integer; it is used to get input to the vector
int intInp;
This iterates from 0 to n-1
for (int i = 0; i < n; i++) {
This gets each input
cin >> intInp;
This passes the input to the vector
intVect.push_back(intInp); }
This iterates from n - 1 to 0; i.e. in reverse and printe the vector elements in reverse
for (int i = n-1; i >=0; i--) { cout << intVect[i] << " "; }

using namespace std;
int main()//main method
{
int runTimes[] = {800, 775, 790, 805, 808};//defining array of integer
for(int x=0;x<3;x++)//defining for loop to print three element of array value
{
printf("%d\n",runTimes[x]);//print array value
}
return 0;
}
Output:

Suppose that you write a subclass of Insect named Ant. You add a new method named doSomething to the Ant class. You write a client class that instantiates an Ant object and invokes the doSomething method. Which of the following Ant declarations willnot permit this? (2 points)I. Insect a = new Ant ();II. Ant a = new Ant ();III. Ant a = new Insect ();1) I only2) II only3) III only4) I and II only5) I and III only
Answer:
5) I and III only
Explanation:
From the declarations listed both declarations I and III will not permit calling the doSomething() method. This is because in declaration I you are creating a superclass variable but initializing the subclass. In declaration III you are doing the opposite, which would work in Java but only if you cast the subclass to the superclass that you are initializing the variable with. Therefore, in these options the only viable one that will work without error will be II.

If there is only one copy of an element, it is not removed. The list size should shrink accordingly based on the number of duplicates removed.
Answer:
removeDuplicates() function:-
//removeDuplicates() function removes duplicate elements form linked list.
void removeDuplicates() {
//declare 3 ListNode pointers ptr1,ptr2 and duplicate.
//initially, all points to null.
ListNode ptr1 = null, ptr2 = null, duplicate = null;
//make ptr1 equals to head.
ptr1 = head;
//run while loop till ptr1 points to second last node.
//pick elements one by one..
while (ptr1 != null && ptr1.next != null)
{
// make ptr2 equals to ptr1.
//or make ptr2 points to same node as ptr1.
ptr2 = ptr1;
//run second while loop to compare all elements with above selected element(ptr1->val).
while (ptr2.next != null)
{

Explanation:
Write a class called Student that has two private data members - the student's name and grade. It should have an init method that takes two values and uses them to initialize the data members. It should have a get_grade method.
Answer:
Explanation:
The following class is written in Python as it is the language that uses the init method. The class contains all of the data members as requested as well as the init and get_grade method. It also contains a setter method for both data variables and a get_name method as well. The code can also be seen in the attached image below.
class Student:
_name = ""
_grade = ""
def __init__(self, name, grade):
self._name = name
self._grade = grade
def set_name(self, name):
self._name = name
def set_grade(self, grade):
self._grade = grade
def get_name(self):
return self._name
def get_grade(self):
return self._grade
