Answer:
(A) A SMTP is a guideline that allows a client to send a message to the server in a network.
The web based mail is a kind of interface by which a correspondence occurs by applying the web explicit conventions or standards fro most of the time.
(B)The pros of an SMTP based two tie client server architecture are that, it has a free platform and a simple set up, also a detailed conversation between a client and a server.
The cons involve, having a blocked SMTP ports, and the slow execution of mass mail.
For the Web based the pros are, no blockages are found, email responses are very quick.
It's cons are, it has a complex kind of arrangement.
(C)What is recommended in this case for DRU is to use the SMTP based two tier client server architecture because, it is quicker, faster, secure and easy to fix.
Explanation:
Solution
(A) A Simple Mail Transfer Protocol (SMTP) is a standard in a which a customer sends messages over to the server in a network.
The sending of emails determines the manner of communication between the server and customer or client. this starts of with a TCP association with a particular port. the customer sends out different snippets of data, and then the server needs to have to look for the verification and email.
A web based email is a kind of interface where the correspondence occurs by making use of web -explicit conventions, for most of the time, the HTTP will allow you to integrate capacities from assistance coming from outside into your application.

Internally, a bin heap is typically implemented as a BST that has the additional ordering property that the minimum value is at the root (or the maximum value is at the root, if we chose to make the bin heap to be a max heap).
a) True
b) False
Answer:
True is the correct answer to the given question .
Explanation:
Heap is the complete binary tree that meets the property of organizing the heap There are two types heap max heap and min heap .The value in the heap of every node is greater than or equal to its parent 's value or less then equal to the parent with there dimension of the minimum value or the maximum value just at the root.
So the binary heap is configured as a Binary Search Tree with the external organizing attribute that perhaps the mean price is in the root with maximum value .Therefore the given statement is true .
The list of lists below is meant to represent the money raised by a charity over multiple days. The inner lists represent each donation, and the outer list represents each day. Use a for loop to calculate the sum of all the numbers in this list of list of numbers, to print the total amount of money raised.
code given:hourly_donations_per_day = [[44, 33, 56, 27, 33, 25],[12, 15, 22, 19, 21],[36, 34, 32, 37, 28, 11, 35],[20, 19, 29],[22, 27, 21, 15, 26, 15]]
Answer:
Following are the code to this question:
hourly_donations_per_day = [ #declaring list of lists and assign values
[44, 33, 56, 27, 33, 25],
[12, 15, 22, 19, 21],
[36, 34, 32, 37, 28, 11, 35],
[20, 19, 29],
[22, 27, 21, 15, 26, 15]
]
total_amount_of_money_raised = 0#defining a variable and assign a values 0
for i in hourly_donations_per_day:#defining loop to count values donation
if isinstance(i,list): #using if block to add donation values
for j in i:#defining loop for add list values
total_amount_of_money_raised += j #add all values in total_amount_of_money_raised variable
print(total_amount_of_money_raised) #print value
Output:
714
Explanation:
In the above code, a list of the list is declared in which, it assigns the multiple values, in the inner lists it represents donation value and in the outer list it represents the day. In the next step, a variable "total_amount_of_money_raised" is declared that assigns a value 0, in the next step, multiple for loop is declared which is used to add list donation value and at the last print, the method is used to print its value.Complete the method, print Multiples(), that takes in a positive integer n, and another positive integer, max. Print out all the multiples of n that are less than or equal to max. Print each multiple on a separate line. For example, if the method is called with n
Answer:
public static void printMultiples(int n, int max){
for (int i=1; i<=max; i++){
if(i%n == 0)
System.out.println(i);
}
}
Explanation:
Create a method called printMultiples that takes two parameters n and max
Inside the method, create a for loop that iterates from 1 to max. If i, a number between 1 and max, % n is equal to 0, that means the number is a multiple of n, print the number.
What are entity-relationship diagrams and how are they used? What symbol is used for a relationship? What is an associative entity? Provide an example.
Answer:
The definition including its given problem is outlined in the following segment on the clarification.
Explanation:
Entity-relationship (ER) diagram describes how mechanical stored procedures are constructed and demonstrate the overarching representation of the situation. It also describes the connections between some of the entities of the framework and even the comparison with standard measurements.For something like an individual relationship structure, the normal representation of connections seems to be a diamond. Associative institutions have several to many partnerships to communicate with. It's indeed the verb throughout a diamond-shaped form that holds two organizations around each other. This verb is in fact an entity on its own, therefore it must be termed an associative entity.An illustration of such might be if a participant were to register for a class. Multiple individuals will be registered for several courses, and there have been many to several relationships; thus, the associative object will indeed register.DOLLAR GENERAL

Open the Undergrad Debt data in the Excel file. Nationally, on average, a college student last year graduated with $27,200 in debt with a historical standard deviation of $5,000. The file gives sample date from Arkansas.
Does Arkansas students have higher debt than the national average at alpha equal to 10?
Answer:
Arkansas students have higher debt than the national average, $27,200.
Explanation:
The provided data is:
S = {24040, 19153, 26762, 31923, 31533, 34207, 14623, 24370, 31016}
In this case we need to test whether Arkansas students have higher debt than the national average at alpha equal to 0.10.
The hypothesis can be defined as follows:
H₀: Arkansas students does not have higher debt than the national average, i.e. μ ≤ $27,200.
Hₐ: Arkansas students have higher debt than the national average, i.e. μ > $27,200.
Compute the sample mean:
[tex]\bar x=\frac{1}{n}\sum X=\frac{1}{10}\times 213537=21353.70[/tex]
As the population standard deviation is provided, we will use a z-test for single mean.
Compute the test statistic value as follows:
[tex]z=\frac{\bar x-\mu}{\sigma/\sqrt{n}}=\frac{21353.70-27200}{5000/\sqrt{10}}=-3.70[/tex]
The test statistic value is -3.70.
Decision rule:
If the p-value of the test is less than the significance level then the null hypothesis will be rejected.
Compute the p-value for the test as follows:
[tex]p-value=P(Z>-3.70)=P(Z<-3.70)=0.00011[/tex]
*Use a z-table for the probability.
The p-value of the test is 0.00011.
p-value = 0.00011 < α = 0.10
The null hypothesis will be rejected.
Thus, it can be concluded that Arkansas students have higher debt than the national average, $27,200.
Two stations running TCP/IP are engaged in transferring a file. This file is 1000MB long, the payload size is 100 bytes, and the negotiated window size is 1000 bytes. The sender receives an ACK 1200 from the receiver.
Requried:
a. Which bytes will be sent next?
b. What is the last byte number that can be sent without an ACK being sent by the receiver?
Answer:
a. 2100
b. 2199
Explanation:
GIven that:
The file size = 1000 MB
The payload size is = 100 bytes
The negotiated window size is = 1000 bytes.
This implies that the sliding window can accommodate maximum number of 10 packets
The sender receives an ACK 1200 from the receiver.
Total byte of the file is :
1000 MB = 1024000000 bytes
a.
Sender receives an ACK 1200 from the receiver but still two packets are still unacknowledged
=1200 + 9 * 100
= 1200 + 900
= 2100
b. What is the last byte number that can be sent without an ACK being sent by the receiver?
b. Usually byte number starts from zero, in the first packet, the last byte will be 99 because it is in 1000th place.
Thus; the last byte number send is :
= 1200 + 10 *100 -1
= 1200 + 1000-1
= 1200 + 999
= 2199
Write an expression using membership operators that prints "Special number" if special_num is one of the special numbers stored in the list special_list
Answer:
In python, the statement can be written as:
if(special_num in special_list): print("Special Number")
Explanation:
We need to create a list with the name 'special_list' with some values and then check whether special_num is in the list or not using the membership operator.
Membership operator in python: in
Let us do it step by step in python:
special_list = ['1', '2', '3','4'] #A list with the values 1, 2, 3 and 4
special_num = input("Enter the number to be checked as special \t")
#Taking the input from the user in the variable special_num.
if(special_num in special_list): print("Special Number")
#Using the membership operator in to check whether it exists in the list or not.
Please refer to the image attached for the execution of above program.
So, the answer is:
In python, the statement can be written as:
if(special_num in special_list): print("Special Number")

php Exercise 3: Function Write a function named word_count that accepts a string as its parameter and returns the number of words in the string. A word is a sequence of one or more non-space characters (any character other than ' '). For example, the call of word_count("hello, how are you?") should return 4. Constraints: • Do not use any data structures such as arrays to help you solve this problem. • Do not use the String function explode on this problem. • But you can declare as many simple variables like Integer, String, etc. as you like. Keep it simple.
Answer:
<?php
function word_count($string){ // function that takes a string a parameter and returns the number of words in that string
$space = 0; // this variable is used in order to detect space, new line and tab spaces in a string
$words = 1; // this variable is used to identify word presence in string
$include = $space; //used to maintain the state of $words and $space
$counter = 0; // this counts the number of words in the string
$i = 0; //this moves through each character of the string
while ($i < strlen($string)){ // iterates through every character of string until the last character of string is reached
if ($string[$i] == " "||$string[$i] == "\n" || $string[$i] == "\t") //if the space or new line or tab space is identified in the string
$include = $space; //set the state of include as space if the next character is a space newline or a tab space
else if ($include == $space) { //if next character is a word and current state i.e. $include holds $space
$include = $words; // then set the state i.e. $include as $words
++$counter; } //increments i to move to next character at each iteration
++$i; } //returns the number of words in a string
return $counter; }
$str = "Hello, how are you "; //sample string
echo "Words: " . word_count($str); // calls word_count function to return number of words in str.
?>
Explanation:
The program has a function word_count that accepts a string as its parameter and returns the number of words in the string. In the function there are three variables $space and $words and $include used as state variables. For instance $space identifies space, new line and tab spaces in the $string so it specifies that a space has occurred. $words identifies words in the $string so it specifies that a word has occurred. $include holds this state information. $i moves through every character of the $string and when a space occurs in the $string then the state $include is set to $space. When a word occurs then state $include is set to $words. $counter variable, which is used to count the number of words is incremented to 1 when previous state is $space and next character is a word character. Every time a word is seen in the string, this variable is incremented to 1 to keep track of number of words in the string. When $i reaches the end of the string then this loop stops and counter returns the number of words in the $string.
James has a USB flash drive that he has used at work. The drive needs to be thrown away, but James wants to make sure that the data is no longer on the drive before he throws it away. What can James use to wipe the data clean?
a. Zero-fill utility
b. Format the drive
c. ATA Secure Erase
d. Smash the USB drive
Answer:
C. ATA Secure Erase
D. Smash the USB drive
Explanation:
Zero fill utility is a specialized way of formatting a storage device particularly secondary storage such as hard disk, flash drive e.t.c. In this process, the disk contents are overwritten with zeros. Once this has been done, undoing is essentially hard but possible. In most cases, this might just mean that the data content is corrupt and as such might still be recovered, maybe not in its pure entirety.
Formatting the drive on another hand does not essentially mean cleaning the drive and wiping off data. It just means that operating systems cannot see those data contents anymore. They are still present in the drive and can be recovered.
ATA Secure Erase is actually a way of completely and permanently erasing the content in a drive. Once the function has been done, undoing is not possible. Both the data content and even the data management table will be completely gone.
Smashing the USB drive is the surest way of cleaning data as that will permanently destroy the working components of the drive such as the memory chip. And once that happens then there's no drive let alone its contents.
All the protocol layers of the internet (Application, Transport. Network) were originally without any security. TLS is one of the security architectures added later. In the Internet protocol stack. TLS is located:________. 1. right above the application layer 2. right below the application layer 3. right below the transport layer 4. right above the IP layer
Answer:
2. right below the application layer
Explanation:
TLS (Transport Layer Security) is an improved and more secured version of the SSL (Secure Socket Layer) used as cryptographic protocol for providing authentication and encryption over a network. It is initialized at the transport layer of the IP stack and finalized at the application layer. In other words, it is located between the transport and application layer of the Internet protocol stack. And this is necessary so that data received in the application layer from the transport layer are protected from start to end between these two layers.
Therefore, it is safe to say that the TLS is located right below the application layer.
Rijndael, AES, CCMP are same as well as different. They are same in terms of how encryption is done and different in terms of whether each one is a protocol, algorithm or a standard.CCMP is both, a protocol and a standard, Rijndael is:_________ a) standard only b) an algorithm c) a communications protocol. d) patented by US Government
Answer:
Option (b) is the correct answer to this question.
Explanation:
AES is based on Rijndael Algorithm.
The Rijndael algorithm enables a choice of block sizes and key sizes. The choices are for each of 128, 192, or 256 bits. Once NIST implemented Rijndael for AES, it only specified one block size,128 bits, but maintained three major lengths of selection. IEEE 802.11I go a step and further limits when both the main size and length of the block for 128 bits. It simplifies deployment and relieves users during development from having to make yet again another decision.
Other options are incorrect because they are not related to the given scenario.
Consider the following algorithm. x â 1 for i is in {1, 2, 3, 4} do for j is in {1, 2, 3} do x â x + x for k is in {1, 2, 3, 4, 5} do x â x + 1 x â x + 5 Count the number of + operations done by this algorithm.
Answer:
Number of + operation done by this algorithm is 60
Explanation:
i = 4
j = 3
k = 6
Now, let "n" be number of '+' operations
n = i × j + i × 2k
substituting the figures
n = 4 × 3 + 4 × (2 × 6)
n = 12 + 4 × 12
n = 12 + 48

The blank function returns to the first character or characters in a text string based on the number of characters specified??? A. PROPER B. MID C. LEN D. LEFT
Answer: D.) LEFT
Explanation: LEFT is an excel function allows users to extract a specified number of characters starting from the left. The syntax goes thus :
=LEFT(text, [num_chars])
text: the original string in which characters are to be extracted.
num_chars : takes an integer, stating the number of characters to extract.
The proper function is also an excel function which sets the first character in each word to uppercase. The mid function is also used in text extraction starting from any position in the original string based on what is specified.
The LEN function is used to get the number or length of characters in a string.
Write the definition of the function displaySubMenu that displays the following menu; this function doesn't collect the user's input; only display the following menu:
[S]top – Press 'S' to stop.
Answer:
Using Python:
def displaySubMenu():
print("[S]top – Press ‘S’ to stop.")
Using C++ programming language:
void displaySubMenu(){
cout<<"[S]top – Press ‘S’ to stop.";}
Explanation:
The function displaySubMenu() has a print statement that prints the following message when this function is called:
[S]top – Press 'S' to stop.
You can invoke this function simply by calling this function as:
displaySubMenu()
The function doesn't take any input from the user and just displays this message on output screen whenever this function is called.
In C++ you can simply call the function using following statement:
void main(){
displaySubMenu(); }
Write a python function absDiff(...) that takes two integers as parameters, gets the absolute value of both, subtracts the second from the first, and returns the difference.
Explanation:
Remember, an absolute value is the non-negative value of a number in this case the integer.
First, using the abs() function. Here's an example:
# Some random integers
variableA = -308
variableB = 301
Second, # Get the absolute values of those integers
absA = abs(variableA)
absB = abs(variableB)
Next,
# Output the results
print("Absolute values of integers with `abs()`:")
print("|", variableA, "| = ", absA, sep="")
Finally,
Use abs(variableA-variableB):
In [1]: abs(-308-301)
Out[1]: 307
For vulnerable road users, the areas where roadways transition from one environment to another are...
A. the safest areas.
B. the most clearly marked areas.
C. the most dangerous areas.
For vulnerable road users, the areas where roadways transition from one environment to another are the most dangerous areas. Thus the correct answer is C.
What is the environment?An environment is refers to surroundings in which all the living and nonliving objects exist to survive life. This includes humans, animals, plants, and other resources.
the areas where roadways transition from one environment to another are the most dangerous areas because here drivers first recognize an approaching change in the nature of the roadway and then reduce their speed as appropriate.
Therefore, option C is appropriate.

Write a Java application with a main() to find the two largest distinct integers entered on the command line by the user. We are just creating a simple stand-alone application. All your code can be in main().
Answer:
import java.util.Scanner; // Scanner class is to use input output functions
public class TwoDistinctLargest //class to find two distinct largest nos
{
public static void main(String[] args) { //start of main() function
Scanner input = new Scanner(System.in); // creates Scanner type object
int integers = 0, largest1 = 0, largest2 = 0; // declare variables
/* integers holds the input integer values, largest1 has 1st largest number and largest 2 contains second distinct largest number, i is used as the count variable to move through the input integers */
int i = 0;
//prompts user to enter integers and enter 0 to stop
System.out.println("Enter the integers (press 0 to stop): ");
integers = input.nextInt(); //reads and scans input integers
while(integers != 0) {
/* the loop keeps taking integer values from user until the value of integers is equal to 0, this means until the user enters 0 */
//checks if the value of integer is greater than first largest computed number
if(integers > largest1) {
//if the value in largest1 is greater than that of largest2
if(largest1 > largest2) {
largest2 = largest1; } // then value of largest1 is set to largest2
largest1 = integers; // largest1 now holds the value of integers //which means largest1 holds the first distinct largest integer
} else { //checks if the value of integers is greater than largest2
if(integers > largest2) {
//if the value of integers is not equal to that of largest1
if(integers!=largest1) {
// set the value of second distinct largest number to largest2
largest2 = integers;} } }
i++; //keeps moving to the next input integer
integers = input.nextInt(); //keeps taking input integers }
//prints the two distinct largest integers
System.out.println("\n The 1st largest distinct integer is " + largest1);
System.out.println("\n The 2nd largest distinct integer is " + largest2); } }
Explanation:
Lets suppose the user inputs the following integers
1, 6, 5, 6, 0
Initial values are:
integers = 0
largest1 = 0
largest2 = 0
i = 0
When the user enters 1, then value of integers = 1
while loop checks if integers!=0. As integers =1 so the program enters the body of while loop. The first IF condition is checked if(integers > largest1)
As largest1 = 0 and integers =1 so this condition evaluates to true as 1 > 0
So the statements in the body of this IF condition are executed. This if conditions contains another if statement if(largest1 > largest2) which checks if the value largest1 is greater than that of largest2. Its false because largest1 =0 and largest2 =0 so largest1 = largest2, so the statement of this if condition body will not execute and program moves to this largest1 = integers; statement which sets the value of integers i.e. 1 to largest1. So the value of largest1 = 1
Now the i is incremented by 1 and it points at second value of integers= 6.
while loop checks if integers!=0. As integers =6 so the program enters the body of while loop. The first IF condition is checked if(integers > largest1)
As largest1 = 1 and integers =6 so this condition evaluates to true as 6>1
So the statements in the body of this IF condition are executed. This if conditions contains another if statement if(largest1 > largest2) which checks if the value largest1 is greater than that of largest2.
Its true because largest1 =1 and largest2 =0 so largest1 > largest2, so the next statement is executed largest2 = largest1; So now the value of largest2=1.
Now program moves to this largest1 = integers; statement which sets the value of integers i.e. 6 to largest1. So the value of largest1 = 6
Now the i is incremented by 1 and it points at second value of integers= 5.
while loop condition is again true. IF condition is checked if(integers > largest1)
As largest1 = 6 and integers =5 so this condition evaluates to false as 5<6. So this IF part will not execute and program control moves to the else part.
Else part has an if condition if(integers > largest2) which evaluates to true because integers = 5 and largest2 = 1 so the program moves to next if statement inside the previous if statement of else part i.e. if(integers!=largest1). This if statement is the main statement which will help in finding two distinct largest numbers in case the same largest value is input more than once. It checks If the value of integers is not equal to largest1 value. As integers = 5 and largest1 = 6 so this if condition is true. If this condition is not used in this program then largest2 will not be assigned distinct largest values but assigned 6 for both largest1 and largest2 as 6 is input twice. Next this if statement largest2 = integers assigns value of integers to largest2 which is the second largest distinct integer.
Now the i is incremented by 1 integers value become 0.
while loop checks if integers!=0. As integers =0 so the while loop breaks. The last two print statements which produce following output.
The 1st largest distinct integer is: 6
The 2nd largest distinct integer is: 5

Complete Question:
A network security analyst received an alert about a potential malware threat on a user’s computer. What can the analyst review to get detailed information about this compromise? Check all that apply.
A. Logs.
B. Full Disk Encryption (FDE).
C. Binary whitelisting software.
D. Security Information and Event Management (SIEM) system.
Answer:
A. Logs.
D. Security Information and Event Management (SIEM) system.
Explanation:
If a network security analyst received an alert about a potential malware threat on a user’s computer. In order to get a detailed information about this compromise, the analyst should review both the logs and Security Information and Event Management (SIEM) system.
In Computer science, logs can be defined as records of events triggered by a user, operating system and other software applications running on a computer. Log files are used to gather information stored on a computer such as user activities, system performance and software program.
Security Information and Event Management (SIEM) system is the process of gathering and integration of all the logs generated by a computer from various software application, service, process, or security tool.
These logs collected through the SIEM are shown in a format that is readable by the security analyst and this help in real-time detection of threats.
Hence, logs and SIEM systems are important tools for network security analyst for detection of threats in real-time and event management functions.
