Select the correct statements regarding Asynchronous Transfer Mode (ATM): a. ATM is a fixed-length cell standard that supports voice, video and data b. ATM is connection-oriented c. ATM offers predictability regarding latency; therefore ATM can offer quality-of-service (QoS) to users d. All of the above are correct
Answer:
D. All of the above are correct.
Explanation:
Asynchronous Transfer Mode is a fixed-length cell structure which allows cells to support voice, video and data. Voice data can be converted to packets and shared with large packet data. Because voice packets, encounter queuing delays, they ought to be of the same size or length.
ATM provides a route between two end points and that is why it can be said to be connection oriented. There is an ease of switching in hardware because of the fixed structure of the ATM. It also offers predictability regarding latency which could be either high or low. So, all of the above satisfy the mode of operation of the Asynchronous Transfer Mode.
Which of the following can be considered beta testing? A programmer at Linus Systems checks the integration of multiple modules of an information system. System users at URP feed data into a new information system to test its capability. MNP Inc. checks the system to ensure that it meets all the necessary design requirements. Taro Inc. checks the correctness of the modules in its new information system. Software testers compare the finished system against user requirements to see if it satisfies all necessary criteria.
Final answer:
System users at URP feeding data into a new information system to test its capability represents beta testing, where real users assess the software in real-world conditions.
Explanation:
The scenario that can be considered beta testing is when system users at URP feed data into a new information system to test its capability. Beta testing involves real users testing the software in a production environment to identify any unresolved bugs or issues before the official release. It is typically the last type of testing done after in-house tests such as unit testing and integration testing have been completed.
In beta testing, the goal is to assess how well the software performs under real-world conditions and to gather feedback from users that can be used to further improve the product's design. This is consistent with the cycle of prototyping, testing, and refinement discussed in the provided references, where testing and evaluation reveal weaknesses or potential improvements, and the design may be adjusted accordingly.
Other scenarios described may represent different levels and types of testing such as integration testing, system testing, or validation testing, which occur before beta testing in the software development lifecycle.
1. INTRODUCTION In this project, you will gain experience with many of the Python elements you’ve learned so far, including functions, repetition structures (loops), input validation, exception handling. and working with strings 2. PROBLEM DEFINITION Present the user with the following menu within a continuous loop. The loop will exit only when the user selects option 7. 1. Enter a string 2. Display the string 3. Reverse the string 4. Append a string to the existing one 5. Slice the string 6. Display the number of occurrences of each letter 7. Quit Program operation: Option 1: Prompt the user to enter a string. Option 2: Display the string to the user. Option 3: Reverse the string and display it to the user. Option 4: Prompt the user to enter a string, then append (i.e. concatenate) it to the end of the existing string. Option 5: Prompt the user for the first and second integers of a slice operation, then replace the existing string with a sliced version of it. Option 6: Print on a separate line each alphabetic character contained in the string. Don’t worry about punctuation, special characters, or whitespace. The letters are not to be considered case-sensitive, so you are free to display them either upper or lower case. Along with each letter, display number of occurrences within the string. For example, if the string is "Hello, World", the output would be: h, 1 e, 1 l, 3 o, 2 w, 1 r, 1 d, 1

You're helping Professor Joy to calculate the grades for his course. The way his course is organised, students take two exams and their final grade is the weighted average of the two scores, where their lowest score weights 70% and their highest score 30%. To accomplish this, you are going to need to do the following: (1) Build the Student named tuple with the following attributes: name (string) exam1 (float) exam2 (float) (2) Write a function create_student, which will ask the user to input a single student's name, exam 1 score, and exam 2 score. The function will then create a named tuple with this information and return it. (3) Write a function create_class, which an integer n as a parameter, and calls create_student n times and returns a list with the n students created. (4) Write a function calculate_score, which takes a single Student named tuple as a parameter, and returns the final score, where their lowest grade is weighted 70% and their highest grade is weighted 30%.

You are in the middle of restarting your computer when the power goes out in the building. When the power is restored, your computer will not restart. When you push the button to turn on the computer, nothing happens. You do not have video on your monitor, but the monitor will turn on. You also notice that you don't hear fans spinning and no indicator lights show on your computer. The monitor is on the same power strip as your computer. What might be the problem?
Answer:
The Power supply has been damaged.
Explanation:
There is no video on the monitor, but the monitor is tamed on. Also, there is no fan spinning sound. What this means is that the Power supply is not working, because fan is unable to work. The light of monitor is on because the direct power supply from the building is fate.
Note: In case of CMOS RAM is damaged, or processor is damaged, CPU fan will run properly until and unless the power supply is not enough.
The partners of a small architectural firm are constantly busy with evolving client requirements. To meet the needs of their clients, the architects must visit several job sites per day. To share and send sensitive project/client information back to the office or with clients, the employees dial into the IPSec-based VPN remotely. For classified proprietary information, two separate extranets were set up with partners in the engineering firm on a server housed inside the office.
What firewall setup would provide the firm both flexibility and security? Justify your response.
Answer:
Check the explanation
Explanation:
IPSec-based VPN is configured in two different modes namely
IPSec Tunnel mode and IPSec Transport mode so here we are using IPsec transport mode which is used for end to end communications between a client and a server in this original IP header is remain intact except the IP protocol field is changed and the original protocol field value is saved in the IPSec trailer to be restored when the packet is decrypted on the other side due to this arrangement you need to use application based firewall because there are certain specific rules that can address the particular field (explained above-change in IP protocol field) which at the other end need to be same so at the type of decryption, original IP protocol field can be matched.

Mobile providers can be susceptible to poor coverage indoors as a result of: a high degree of latency. network congestion that clogs up the network traffic. an increase in bandwidth demand placed on their networks. spectrum used by most mobile phone firms that does not travel well through solid objects. a lack of sufficient number of towers owing to the not-in-my-backyard problem.
Answer:
C. spectrum used by most mobile phone firms that does not travel well through solid objects.
Explanation:
Obstructions on the path of radio waves can result to poor network coverage. This is also called Phone reception or coverage black spot. Just as an obstruction on the path of light waves causes the emergence of shadows, so also an obstruction from waves coming from the cell tower. Common culprits are windows, doors, roofing materials, and walls. These solid objects cause an interruption of network for network providers inside a building.
The use of antennas connected from outside the building to inside can be helpful in reducing the effect of this obstruction. Problems resulting could be low signal, difficulty hearing a caller at the other end, slow internet connection, etc.
Priscilla is providing the junior analysts in her firm with some real-world illustrations to explain some of the recommendations that they must be prepared to make to clients, based on what they have studied in their coursework, in order to solidify their understanding. Which is a reason Priscilla will share with the new analysts for recommending that a client purchase a software package?
Options:
a) The client wants to develop internal resources and capabilities
b) The client is looking for the lowest possible costs
c) The client has unique business requirement that must be satisfied by this software application
d) The client has some existing technology in place whose requirements must be met by the new software
Answer:
d) The client has some existing technology in place whose requirements must be met by the new software
Explanation:
For a client to purchase a software, the client has an already existing technology that requires that software for adequate functioning. The analyst will recommend the new software to the client based on the technology he/she previously has and the requirements he wants to meet.
The other options are not impossible, but they are not the primary reason why the software will be purchased, the overall aim for all the company's activities may be to develop internal resources and capabilities or to meet some unique business requirements, but these are secondary. The primary purpose is that the client has a technology that cannot function properly without the recommended software.
Which of the following entries into the username and password fields will NOT cause us to gain admin access? You may assume that the system grants access when a legitimate username/password combo is entered. Count the text inside the double quotation marks, but not the marks themselves. For example, a user would enter ("username", "password") and gain access. You may assume that the password to the admin account is not "asdf"

can someone please help i have no idea what’s going on in this code
Explanation:
The first 3 lines of code tell the user to input a 5 digit number (ex. 72,910) or a 1 digit number (ex. 3). The next 5 lines of code determine if it is a 5/1 digit number or not. If it is, it prints "Success!". The rest of the code just tells that if it's not a 5/1 digit number, and if it's not, it gives errors and tells the user to try again.
Hope this helps!
Jim is a forensic specialist. He seized a suspect computer from a crime scene, removed the hard drive and bagged it, documented and labeled the equipment, took photographs, completed a chain of custody form, and locked the computer in his car. On the way to the lab, he stopped to purchase supplies to use at the next crime scene. What did Jim do wrong
Answer: Jim left the computer unattended while shopping for supplies to be used at the next crime scene.
Explanation: While transporting the evidence to a secure location (lab), he left the computer unattended in his car and goes shopping for supplies that will be used in his next crime scenes. This act will give the criminals or their accomplice the opportunity to break into his car and tamper with what ever evidence he might have left behind in his car.
A computer company has $3840000 in research and development costs. Before accounting for these costs, the net income of the company is $2580000. What is the amount of net income or loss before taxes after these research and development costs are accounted for?
Answer:
The answer is "loss of 1,260,000"
Explanation:
Following are the important points of the question:
The cost of research and development is = $3840000
net income of the company is= $2580000
Find: loss or profit .
According to the rate of the cost, the company cost is higher than the company rate. So, the company goes in loss stage, then
Loss = total cost - net income
Loss = $3840000 - $2580000
Loss= $ 1,260,000
The computer company would face a net loss of $1,260,000.
The question is asking about the calculation of net income or loss for a computer company after accounting for research and development costs. To determine the net income or loss, we subtract the research and development (R&D) costs from the company's income before these costs are accounted for.
So, if the net income before R&D costs is $2,580,000 and the R&D costs are $3,840,000, we perform the following calculation:
Net Income after R&D = Net Income before R&D - R&D costs
Net Income after R&D = $2,580,000 - $3,840,000
Net Income after R&D = -$1,260,000
This result is a net loss of $1,260,000 after accounting for R&D costs.

The Counter Pattern
This pattern is one of the most important ones in all of programming.
It is used to increase the value of a variable by 1. You might call it the counter pattern since it can be used to make a variable that counts up. You'll use this pattern a lot, especially with the draw loop. Let's see what that looks like.
Do This
This program creates a variable counter and then uses the counter pattern to make it count up. When you run the program what do you think you'll see on the screen?

Write a function shampoo_instructions() with parameter num_cycles. If num_cycles is less than 1, print "Too few.". If more than 4, print "Too many.". Else, print "N : Lather and rinse." num_cycles times, where N is the cycle number, followed by "Done.". Sample output with input: 2 1 : Lather and rinse. 2 : Lather and rinse. Done. Hint: Define and use a loop variable.
Answer:
def print_shampoo_instructions(num_cycles):
if num_cycles < 1:
print("Too few.")
elif num_cycles >4:
print("Too many.")
else:
N = 1
for N in range (N,num_cycles+1):
print(N,": Lather and rinse.")
print("Done.")
Explanation:
Final answer:
The function shampoo_instructions() controls repetitions based on input, preventing infinite loops, akin to the shampoo instructions' issue. It emphasizes the importance of iteration control in programming loops to avoid endless execution. Understanding how to manage loop cycles prevents program malfunction due to infinite loops.
Explanation:
shampoo_instructions() is a function that takes a parameter num_cycles and prints instructions based on the input. If num_cycles is less than 1, it prints 'Too few.'; if more than 4, it prints 'Too many.'; otherwise, it prints the cycle number followed by 'Lather and rinse.' num_cycles times.The directions on shampoo create an infinite loop since they lack an iteration variable to specify the number of repetitions. In programming, developers must include a mechanism to control loops' execution, preventing infinite iterations.
In a loop, each iteration represents a cycle, akin to the instructions in shampoo; therefore, the concept of controlling the number of repetitions is fundamental to avoid infinite loops and ensure proper program execution.
Consider the following two code segments, which are both intended to determine the longest of the three strings "pea", "pear", and "pearl" that occur in String str. For example, if str has the value "the pear in the bowl", the code segments should both print "pear" and if str has the value "the pea and the pearl", the code segments should both print "pearl". Assume that str contains at least one instance of "pea".
I.
if (str.indexOf("pea") >= 0)
{
System.out.println("pea");
}
else if (str.indexOf("pear") >= 0)
{
System.out.println("pear");
}
else if (str.indexOf("pearl") >= 0)
{
System.out.println("pearl");
}
II.
if (str.indexOf("pearl") >= 0)
{
System.out.println("pearl");
}
else if (str.indexOf("pear") >= 0)
{
System.out.println("pear");
}
else if (str.indexOf("pea") >= 0)
{
System.out.println("pea");
}
Which of the following best describes the output produced by code segment I and code segment II?
Both code segment I and code segment II produce correct output for all values of str.
Neither code segment I nor code segment II produce correct output for all values of str.
Code segment II produces correct output for all values of str, but code segment I produces correct output only for values of str that contain "pear" but not "pearl".
Code segment II produces correct output for all values of str, but code segment I produces correct output only for values of str that contain "pearl".
Code segment II produces correct output for all values of str, but code segment I produces correct output only for values of str that contain "pea" but not "pear".
Answer:
Code segment II produces correct output for all values of str, but code segment I produces correct output only for values of str that contain "pea" but not "pear".
Explanation:
The main issue with the first code segment is the way how the if else if condition are arranged. The "pea" is checked at the earliest time in the first code segment and therefore so long as there is the "pea" exist in the string (regardless there is pear or pearl exist in the string as well), the if condition will become true and display "pea" to terminal. This is the reason why the code segment 1 only work for the values of str that contain "pea".
A mother calls you to report that her 15-year-old daughter has run away from home. She has access to her daughter's e-mail account and says her daughter has a number of emails in her inbox suggesting she has run away to be with a 35-year-old woman. Write a 2 to 3 page paper/report (not including title or reference page) explaining how you should proceed. Make sure you adhere to the grading rubric and write the report in APA format.
Answer: Wait, you're asking strangers to write a report for you? Just use common sense--tell her to forward the emails to the police department, or to provide the login details or the IPv4 logs (depending on the email service) to work off of. Considering that she most likely has the email linked to her phone, you should get into contact with her phone provider to locate the daughter. I don't know what else to say considering that you're asking strangers for an essay to be written for you. Hopefully what I said helps, but I doubt that anyone's going to write a full two page essay.
APA offers authors a dependable structure they can use each time they write. Authors' arguments or research are more effectively organized when they are consistent.
What are advantages to write issue in APA format?The APA format helps papers on usually complex issues to be more understandable. It makes reading and understanding papers easier.
Utilize common sense and instruct her to transmit the emails to the police department, or, depending on the email service, to supply the login information or the IPv4 logs for investigators to use.
You should get in touch with her phone provider to find the daughter because she almost certainly has the email connected to her phone.

Homework assignment number 13 Binary search trees have their best performance when they are balanced, which means that at each noden, the size of the left subtree of n is within one of the size of the right subtree of n. Write a program thatwill take an array of generic values that are in sorted order in the array, create a binary search tree, and put the values in the array into the tree. Your binary search tree should be complete ("complete" as defined in chapter 24). Or put another way, it should have the fewest number of levels and still be "complete".Use the following array: "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M","N".Remember, your code is to handle generic data types, not just strings. So while I want you to use the specified array of strings, your program should work if I choose to use an array of Integers, or Characters.

Final answer:
To create a balanced binary search tree from a sorted array, you can use a recursive approach. Here is an example Java code that can be used as a starting point. The code creates a balanced binary search tree by selecting the middle element as the current node and calling the createBalancedBST method on the left and right subarrays.
Explanation:
In order to create a balanced binary search tree from a sorted array, you can use a recursive approach. Here is an example Java code that can be used as a starting point:
import java.util.ArrayList;
class Node<T> {
Node<T> left;
Node<T> right;
T value;
Node(T value) {
this.value = value;
this.left = null;
this.right = null;
}
}
public class TreeDriver<T extends Comparable<T>> {
Node<T> root;
TreeDriver() {
this.root = null;
}
private Node<T> createBalancedBST(T[] arr, int start, int end) {
if (start > end)
return null;
int mid = (start + end) / 2;
Node<T> node = new Node<>(arr[mid]);
node.left = createBalancedBST(arr, start, mid - 1);
node.right = createBalancedBST(arr, mid + 1, end);
return node;
}
private void inOrderTraversal(Node<T> node) {
if (node == null)
return;
inOrderTraversal(node.left);
System.out.print(node.value + " ");
inOrderTraversal(node.right);
}
public void createAndPrintBalancedBST(T[] arr) {
this.root = createBalancedBST(arr, 0, arr.length - 1);
inOrderTraversal(this.root);
}
public static void main(String[] args) {
TreeDriver<String> tree = new TreeDriver<>();
String[] arr = {"A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M","N"};
tree.createAndPrintBalancedBST(arr);
}
}
The createBalancedBST method takes an array arr, a start index, and an end index. It recursively creates a balanced binary search tree by selecting the middle element as the current node and calling the createBalancedBST method on the left and right subarrays.
The inOrderTraversal method is used to print the values of the created BST in order.
Your friends’ preschool-age daughter Madison has recently learned to spell some simple words. To help encourage this, her parents got her a colorful set of refrigerator magnets featuring the letters of the alphabet (some number of copies of the letter A, some number of copies of the letter B, and so on), and the last time you saw her the two of you spent a while arranging the magnets to spell out words that she knows. Somehow with you and Madison, things always end up getting more elaborate than originally planned, and soon the two of you were trying to spell out words so as to use up all the magnets in the full set – that is, picking words that she knows how to spell, so that once they were all spelled out, each magnet was participating in the spelling of exactly one of the words. (Multiple copies of words are okay here; so for example, if the set of refrigerator magnets includes two copies of each of ‘C,’ ‘A,’ and ‘T,’ it would be okay to spell out "CAT" twice.) This turned out to be pretty difficult, and it was only later that you realized a plausible reason for this. Suppose we consider a general version of the problem of Using Up All the Refrigerator Magnets, where we replace the English alphabet by an arbitrary collection of symbols, and we model Madison’s vocabulary as an arbitrary set of strings over this collection of symbols.
Answer:
See explaination
Explanation:
Given a set U which is the set of magnets where each magnet representing a symbol, but are accepted more copies of the same symbol which we number arbitrarily 1,2,3,. ... For example if we had two copies of the symbol A, we would have elements A 1 ,A 2 ) and subsets S 1 ,...S n which represent words formed from the magnets that Madison knows how to spell. Note that if ‘’CAT” was a word in Madison’s vocabulary, then both of the sets C,A 1 ,T and C,A 2 ,T would appear among the S i . We are interested in the maximum number of disjoint sets (which correspond to words in Madison’s vocabulary that can be simultaneously spelled out by the magnet pieces).
We reduce Independent Set (IS) to Set Packing. Given an instance of IS ( G,k ), we set U to be the set of edges of G . For each vertex v i , we introduce a set S i = { e : e = ( v i ,x ) } which has one element for each edge incident to v i . We claim that G has an independent set of size k iff there are k disjoint sets among the S i . Indeed, if I is an independent set of size k then the k sets S v for v ∈ I have no common elements. Also, if { S i 1 ,...,S i k } are k disjoint sets then the vertices v i 1 ,...,v i k have no edges between them thus they form an independent set of size.
Susan was recently fired from her executive IT position. You have concerns that she has enough knowledge and expertise to sabotage company documents—and you need to delete her access. However, upon beginning, you find information that should be retained in her user directory for future company needs. Consider the process you would take to ensure that Susan no longer has access and that data is retained. In situations like this, do you think the benefits outweigh the risks enough to retain user information? Why or why not?
Answer:
A
To ensure that Susan no longer has access without erasing her files I'll take the following steps:
I'll create a new group and and name it Retired and make sure it has no user privileges at all.Next step is to move Susan's profile to the Retired group. This is ensure that she does not have rights or access to any other user groups.B
The benefits that accrue to retaining her information will depend on the value of information that her account possesses. As the former executive IT personnel, this is most likely the case.
In the long run, the safest thing to do might be to just back up all information she created and had access to to a remote storage or data warehouse.
Cheers!
