Answer:
C. The main method proceeds to the next statement following the t3.join(); statement
Explanation:
join() method allows the thread to wait for another thread and completes its execution. If the thread object is executing, then t3.join() will make that t is terminated before the program executes the instruction. Thread provides the method which allows one thread to another complete its execution. If t is a thread object then t.join() will make that t is terminated before the next instruction. There are three overloaded functions.
join()
join(long mills)
join(long millis, int Nanos)
If multiple threads call the join() methods, then overloading allows the programmer to specify the period. Join is dependent on the OS and will wait .
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 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

These snapshots will provide accurate and up-to-date information allowing for a correct rebuild of the Redshift cluster.
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
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.
If no other row matches, the router will select the ________ row as its best match. First Last either First or Last, depending on the circumstances neither First nor Last
Answer:
Last
Explanation:
Routing is a term in engineering which involves the process of selecting a path for traffic in a network or across multiple networks. It is applicable in circuit-switched networks, such as the public switched telephone network (PSTN), and computer networks, such as the Internet. It is mostly used as a term for IP Routing.
Hence, in IP Routing, the first step is comparing the packet's destination IP address to all rows, followed by selecting the nest-match row. However, If no other row matches, the router will select the LAST row as its best match.

Create a program that will find and display the largest of a list of positive numbers entered by the user. The user should indicate that he/she has finished entering numbers by entering a 0.
Answer:
This program is written using Python Programming language,
The program doesn't make use of comments (See explanation section for line by line explanation)
Program starts here
print("Enter elements into the list. Enter 0 to stop")
newlist = []
b = float(input("User Input: "))
while not b==0:
newlist.append(b)
b = float(input("User Input: "))
newlist.sort()
print("Largest element is:", newlist[-1])
Explanation:
This line gives the user instruction on how to populate the list and how to stop
print("Enter elements into the list. Enter 0 to stop")
This line creates an empty list
newlist = []
This line enables the user to input numbers; float datatype was used to accommodate decimal numbers
b = float(input("User Input: "))
The italicized gets input from the user until s/he enters 0
while not b==0:
newlist.append(b)
b = int(input("User Input: "))
This line sorts the list in ascending order
newlist.sort()
The last element of the sorted list which is the largest element is printed using the next line
print("Largest element is:", newlist[-1])
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.
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.
In the Programming Process which of the following is not involved in defining what the program is to do:_____________ Group of answer choices
a. Compile code
b. Purpose
c. Output
d. Input
e. Process
Answer:
a. Compile code
Explanation:
In programming process, the following are important in defining what a program is to do;
i. Purpose: The first step in writing a program is describing the purpose of the program. This includes the aim, objective and the scope of the program. The purpose of a program should be defined in the program.
ii. Input: It is also important to specify inputs for your program. Inputs are basically data supplied to the program in order to perform a task. Valid inputs are defined in the program.
iii. Output: Many times, when inputs are supplied to a program the resulting effects are shown in the outputs. The way the output will be is defined in the program.
iv. Process: This involves the method by which inputs are being mapped into outputs. The process implements the functionality of the program by converting inputs into their corresponding outputs. The process is defined in the program.
Compile code is not a requirement in defining what a program is to do. It just allows the source code of the program to be converted into a language that the machine understands.

In cell B13, create a formula using the VLOOKUP function that looks up the value from cell A11 in the range A5:B7, returns the value in column 2, and specifies an exact match.
Answer:
VLOOKUP(A11,A5:B7,2,0) is the correct answer to this question.
Explanation:
The VLOOKUP method contains a vertical lookup by scouring for worth in a table's first section and trying to return the significance in the throughout the situation within the same row. The VLOOKUP excel is a built-in function classified as a Lookup / see as.
According to the question:-
The formulation needed to enter is = VLOOKUP(A11, A5: B7,2,0)
The first "A11" here is the cell from which value is retrieved
The second "A5: B7" input is the range for the table where you need to lookup. 2 Is the number of the column from which the value is taken and 0 indicates the exact math
The VLOOKUP function is used to look up a value in a particular column.
The VLOOKUP formula to enter in cell B13 is: VLOOKUP(A11,A5:B7,2,0)
The syntax of a VLOOKUP function is:
VLOOKUP(lookup_value, cell_range, column_index, [return_value])
Where:
lookup_value represents the value to look upcell_range represents the cells to checkcolumn_index represents the column index[return_value] is an optional entry, and it represents the value that will be returned by the look up function.From the question, we have:
lookup_value = cell A11cell_range = cell A5 to B7column_index = 2[return_value] = 0So, the VLOOKUP function would be: VLOOKUP(A11,A5:B7,2,0)

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.

Write a program that first reads in the name of an input file and then reads the file using the csv.reader() method. The file contains a list of words separated by commas. Your program should output the words and their frequencies (the number of times each word appears in the file) without any duplicates.
Answer:
Here is the Python code.
import csv
inputfile = input("Enter name of the file: ")
count = {}
with open(inputfile, 'r') as csvfile:
csvfile = csv.reader(csvfile)
for line in csvfile:
for words in line:
if words not in count.keys():
count[words] = 1
else:
count[words] + 1
print(count)
Explanation:
I will explain the code line by line.
import csv here the css is imported in order to read the file using csv.reader() method
inputfile = input("Enter name of the file: ") This statement takes the name of the input file from the user
count = {} this is basically a dictionary which will store the words in the file and the number of times each word appears in the file.
with open(inputfile, 'r') as csvfile: This statement opens the inputfile using open() method in read mode. This basically opens the input file as csv type
csvfile = csv.reader(csvfile) This statement uses csv.reader() method to read the csv file contents.
for line in csvfile: This outer for loop iterates through each line of the file
for words in line: This inner loop iterates through each word in the line
if words not in count.keys(): This if condition checks if the word is not in the dictionary already. The dictionary holds key value pair and keys() method returns a list of all the keys of dictionary
count[words] = 1 if the word is not present already then assign 1 to the count dictionary
co unt[words] + 1 if the word is already present in dictionary increment count of the words by 1. Suppose the input file contains the following words:
hello,cat,man,hey,dog,boy,Hello,man,cat,woman,dog,Cat,hey,boy
Then because of co unt[words] + 1 statement if the word appears more than once in the file, then it will not be counted. So the output will be:
{' cat': 1, ' man': 1, ' dog': 1, ' woman': 1, ' Hello': 1, ' hey': 1, ' boy': 1, 'hello': 1, ' Cat': 1}
But if you want the program to count those words also in the file that appear more than once, then change this co unt[words] + 1 statement to:
count[words] = count[words] + 1
So if the word is already present in the file its frequency is increased by 1 by incrementing 1 to the count[words]. This will produce the following output:
{' Cat': 1, ' cat': 2, ' boy': 2, ' woman': 1, ' dog': 2, ' hey': 2, ' man': 2, ' Hello': 1, 'hello': 1}
You can see that cat, boy, dog and hey appear twice in the file.
print(count) This statement prints the dictionary contents with words and their frequencies.
The program with its output is attached.
The program is an illustration of file manipulations.
File manipulations involve reading from and writing into files.
The program in Python, where comments are used to explain each line is as follows:
#This imports csv module
import csv
#This initializes a dictionary
kounter = {}
#This gets input for the file name
fname = input("Filename: ")
#This opens and iterates through the file
with open(fname, 'r') as cfile:
#This reads the csv file
cfile = csv.reader(cfile)
#This iterates through each line
for line in cfile:
#This iterates through each word on each line
for words in line:
#This counts the occurrence of each word
if words not in kounter.keys():
kounter[words] = 1
else:
kounter[words] + 1
#This prints the occurrence of each word

The is_positive function should return True if the number received is positive, otherwise it returns None. Can you fill in the gaps to make that happen?
def is_positive(number):
if _____ :
return _____
Answer:
def is_positive(number):
if (number > 0):
return True
else:
return "None"
---------------------------------------------------------------------------------
Code Test and Sample Output:print(is_positive(6))
>> True
print(is_positive(-7))
>> None
----------------------------------------------------------------------------------
Explanation:The code above has been written in Python.
Now, let's explain each of the lines of the code;
Line 1: defines a function called is_positive which takes in a parameter number. i.e
def is_positive(number):
Line 2: checks if the number, supplied as parameter to the function, is positive. A number is positive if it is greater than zero. i.e
if (number > 0):
Line 3: returns a boolean value True if the number is positive. i.e
return True
Line 4: defines the beginning of the else block that is executed if the number is not positive. i.e
else:
Line 5: returns a string value "None" if the number is not positive. i.e
return "None"
All of these put together gives;
===============================
def is_positive(number):
if (number > 0):
return True
else:
return "None"
================================
An example test of the code has also been given where the function was been called with an argument value of 6 and -7. The results were True and None respectively. i.e
print(is_positive(6)) = True
print(is_positive(-7)) = None
Following are the python program to check input number is positive or negative:
Program:def is_positive(n):#defining the method is_positive that takes one variable in parameter
if (n > 0):#defining if block that check input number is positive
return True#return boolean value that is True
else:#else block
return "None"#return string value
n=int(input("Enter number: "))#defining n variable that input a number
print(is_positive(n))#using print method that calls and prints method return value
Output:
please find the attached file.
Program Explanation:
Defining the method "is_positive" that takes one variable "n" in the parameter.Inside the method, if conditional block is defined that checks the input number is positive, if it's true, it will return a boolean value that is "True". Otherwise, it will go to the else block, where it will return a string value that is "None".Outside the method, the "n" variable is declared to be an input number.After the input value, a print method is used that calls the "is_positive" method and prints its return value.Find out more about the method here:

Implement the function:
string get_ap_terms(int a, int d, size_t n);
which returns a string containing the first n terms of the arithmetic progression (AP) as a sequence of comma-separated values.
Answer:
This is written in C++
Check comments for explanations
Program starts here
#include<iostream>
#include<string>
using namespace std;
//The function get_ap_terms begins here
string get_ap_terms(int a, int d, int size_tn)
{
// This line initializes the expected string to empty string
string result = "";
//The for iteration loops through the number of terms the function is expected to return
for(int i = 1; i<= size_tn;i++)
{
//This line checks if the loop is less than the number of terms
if(i < size_tn)
{
//This string gets the current term of the progression
result+=to_string(a)+ ", ";
//This line calculates the next term
a+=d;
}
else
{
//This line calculates the last term
result+=to_string(a);
}
}
//This line returns the string containing the first n terms of the arithmetic progression
return result;
}
//The main function starts here
int main()
{
//This line declares the first term (a), the common difference (d) and the number of terms (size_tn)
int a,d,size_tn;
//This line prompts the user for the first term
cout<<"First Term: ";
//This line gets the first term
cin>>a;
//This line prompts the user for the common difference
cout<<"Common Difference: ";
//This line gets the common difference
cin>>d;
//This line prompts the user for number of terms
cout<<"Number of Terms: ";
//This line gets the number of terms
cin>>size_tn;
//This line calls the function to print the string containing the first n terms
cout<<get_ap_terms(a, d, size_tn);
return 0;
}
//Program ends here
