Answer:
B) Require more processing by each computer in the network than in star and ring networks
Explanation:
Meshnet which refers to mesh networks is one of the topologies of computer networks. In this topology, the nodes are all connected directly to each other and to as many many other nodes that cooperate with each other (nodes here refers to PCs, bridges routers etc), this kind of connection prevents dependence on a single node for communication as all nodes participates in the passing of information, as a result each computer in a mesh requires more processing work than in star and ring networks.
FTP requires confirmation that a file was successfully transmitted to a client, but it has no built-in mechanism to track this information for itself. What protocol does FTP rely on at the Transport layer of the TCP/IP model to ensure delivery is complete?
Group of answer choices
UDP
HTTP
SSH
TCP
Answer:
TCP
Explanation:
Answer:
TCP
Explanation:
FTP (File Transfer Protocol) can be found in the Application layer of the TCP/IP model and the Application layer of the OSI model not on the Transport layer of the TCP/IP model as stated in the question.
In the Transport layer, we have end-to-end message transmission or application connection, which can be grouped as connection-oriented or connectionless. Connection-oriented is implemented in TCP (Transmission Control Protocol) while connectionless is implemented in UDP (User Datagram Protocol), which are the two major protocols found in the Transport Layer of the TCP/IP model. The choice of TCP as the correction option out of the four options given is based on the fact that FTP is a protocol found in the Application layer of TCP/IP
FTP is a network protocol used to receive and send files between machines on a TCP/IP network using ports 20 and 21. This protocol uses a client-server architecture, an FTP client is installed on the client and used to establish the connection to an FTP server running on a remote machine. FTP supports user authentication, so when a connection has been established and the user authenticated, data can be transferred between them. All data are sent in clear text, be it usernames or passwords. For secure transmission that protects the username and password, and encrypts the content, FTP can be secured with SSL.TLS or replaced with SSH File Transfer Protocol (SFTP). A connection to port 21 from the FTP client forms the control stream on which commands are passed to the FTP server and responses are collected. The parameters for the data streams depend on the specifically requested transport mode. Data connection usually uses port 20.
What kind of printer is used with multipart forms such as those with point of sale machines?A) dot-matrixB) daisy-wheelC) inkjetD) color
Answer:
The answer is "Option A".
Explanation:
The Dot matrix printer is also known as an impact matrix printer. It is a multi-part form printer because it prints data on paper. This printer uses a hammer and a ribbon printer, that shapes pictures from dots. and other options are not correct, that can be described as follows:
In option B, daisy-wheel printer prints data on printer only one side that's it is not correct. In option C, the Inkjet printer is capable to print data in multi-part forms, but this printer does not data in continuous forms. In option D, the color printer allows you to print data in color format like images, graphs, and banner. It prints data only on one side, that's why it is not correct.Assume the availability of a function called printStars. The function receives an int argument. If the argument is positive, the function prints (to standard output) the given number of asterisks. Thus, if printStars(8) is called, ******** (8 asterisks) will be printed. Assume further that the variable starCount has been declared and initialized to a some integer, possibly negative or zero. Write some code that does nothing if starCount is not positive but that otherwise prints starCount asterisks to standard output by: first printing a single asterisk (and no other characters) then calls printStars to print the remaining asterisks.
To print asterisks based on the value of 'starCount', you must first check if it is positive. If so, print one asterisk and then call 'printStars(starCount - 1)' to print the rest.
Explanation:To address the scenario wherein the function printStars needs to be called only if starCount is a positive number, we must first check the value of starCount. If starCount is greater than zero, we print a single asterisk and then call printStars with starCount - 1 to print the remaining asterisks. Here's how this could be coded:
if (starCount > 0) {This code snippet checks if starCount is positive and acts accordingly by printing an initial asterisk, followed by the remaining asterisks using the printStars function.
Wayne works for a large law firm and manages network security. It’s common for guests who come to the law firm to need to connect to the WiFi. He wishes to ensure that he provides maximum security when these guests connect using their own devices, but also seeks to provide assurance to the guests that his company will have minimal impact on their devices. What is the best solution?
Answer:
C) Dissolvable NAC agent
Explanation:
Network Access Control systems can perform a health check on devices to make sure they meet minimum security standards prior to connecting. Permanent NAC would have an impact on visitor devices; agentless NAC has less impact and COPE devices aren’t possible to give to guests.
What percentage of users who do not own a Zero UI device were comfortable with an algorithm learning their behaviour?
Answer:
This requires a percentage of people with zero UI device, and how many of them are comfortable with it. The rest can be calculated. However, since it is not given, as an assumption, one should note that more and more people are going to have it, but in the beginning, only a few out of them will be comfortable with it at the start, as it is a new technology.
Explanation:
It's important to understand what is a Zero UI device. This means a touchless UI experience. The era of the touchscreen is going to vanish soon hence, and computers will be able to understand our feelings and gestures. Our gestures will drive the computers now, and that is going to be a new style of UI in the computer world. The era has not yet arrived, but you might soon find that era starting, and at the beginning, people will find it hard though with time they will start feeling comfortable with it.
The logical structure in which one instruction occurs after another with no branching is a _____.
a. case
b. loop
c. sequence
d. selection
Answer:
Option(c) i.e "sequence " is the correct answer for the given question.
Explanation:
In the sequence, the statement or instruction is executed in the sequence manner i.e one after another. In the sequence structure, the instruction is executed in the predetermined order and no instruction are skipped sometimes the sequence structure takes too many times when they are more instruction in a single module.
For Example : Following are the program in c++ of sequence control structure
#include<iostream.h> // header file
using namespace std; // namespace
int main() // main method
{
int a=100; // variable declaration
c=a+100;
cout<<c; // display c
return(0);
}
Output:100
In the above program the instruction a=100,c=a+100 and display c is executed in the sequence manner.
In the Option(a),Option(b) and Option(d) instruction are not executed in one after another so these are incorrect answers.

Explanation:
The description of the given c++ program can be given as:
In the given c++ program two class is defined that is "class bClass and class dClass". In bClass, this class declares a method, parameterized constructor, and private integer variable x and y. In dClass, this class first, inherit the base class that is bClass and this class also declares a method, parameterized constructor, and private integer variable z. In the main method, we create the class object and passed value in the constructor parameter that is "2, 3" and "3, 5, 8" and call the function that is "print". In this method, we use the scope resolution operator that access function and constructor to main method scope. By using a scope resolution operator we define method and constructor.Eamon wants to provide a discount to premium buyers who order in large quantities.

Final answer:
The SDLC steps are matched as problem/opportunity identification as first, analysis as second, design as third, development as fourth, and testing and installation as fifth. The design process is iterative, often involving prototyping, testing, and refinement.
Explanation:
The steps of the Software Development Life Cycle (SDLC) can be matched to their positions in the development process as follows:
Problem/Opportunity Identification - A. first step
Analysis - B. second step
Design - C. third step
Development - D. fourth step
Testing and Installation - E. fifth step
The SDLC is a structured methodology used for the development of software systems and involves several stages from initial problem identification through to the final deployment and maintenance of the solution. In the design process, after evaluating solutions and selecting the best design, as in the example of choosing a solar still for desalination, the team develops a detailed design through prototyping, testing, and refinement. This approach is typically iterative, sometimes referred to as a spiral design process, and may require several iterations as prototypes are created, tested, and reviewed to enhance the design.

Write a loop to populate user_guesses with num_guesses integers. read integers using int(input()). ex: if num_guesses is 3 and user enters 9 5 2, then user_guesses is [9, 5, 2].
Answer:
num_guesses = 3 #initialized number of guesses to 3
user_guesses = [] #declared the user_guesses array
guess = 0 #guess variable initialized to 0
print('Enter a number: ') #prompt telling the user to enter a number
while guess < num_guesses: #loop capturing input and storing into array
num = int(input())
user_guesses.append(num)
guess = guess + 1
#end of loop
print(user_guesses) #array outputted to user
Explanation:
The above program captures numbers from the user and stores into an array (user_guesses), the length of the array is determined by the value contained in the num_guesses variable, it prints the combined input as an array.
Loops are code statements that are used to repetitive statements.
The loop in Python where comments are used to explain each line is as follows:
#This gets input for the number of guesses
num_guesses = int(input())
#This initializes a list for user guess
user_guesses = []
#The following is repeated
for i in range(num_guesses):
#This gets input for the guess
num = int(input())
#This adds the guess to a list
user_guesses.append(num)
#This prints all the guesses by the user

Your friend Luis recently was the victim of identity theft and has asked your advice for how to protect himself in the future. You tell Luis that he should install software that protects network resources from outside intrusions, called a(n) ______.
a. hot spot
b. tracking cookie
c. firewall
d. security scanner
Answer:
Firewall
Explanation:
Firewalls are mainly intended to protect an individual computer system or network from being accessed by an intruder, especially via the Internet. They thus work to prevent sabotage of the system and the theft or unauthorized viewing of private or sensitive data, such as through the use of spyware.
Final answer:
Luis should install a "firewall" to protect against identity theft by serving as a barrier that controls network traffic and prevents unauthorized access to his computer's resources.
Explanation:
To protect yourself from identity theft and ensure the security of your network resources, it's important to install a program known as a firewall. This software acts as a barrier between your computer and the internet, controlling incoming and outgoing network traffic based on an applied rule set. It helps to prevent unauthorized access to your system, which can be crucial for protecting sensitive personal information from cybercriminals.
A firewall is different from programs that monitor Web usage, which may be used in work settings to ensure employees are focused on work-related tasks. While both are concerned with the use of the internet, a firewall is specifically designed to protect against intrusions and hacking attempts.

An application needs to calculate sales tax for purchases. You decide to simplify the code by putting the sales tax calculation in a function. The returned value from the function is then added to the Subtotal, and the result is stored in the decTotal variable. Which of the following statements will call the GetSalesTax function and return a value to be used in the Total calculation?a.) decTotal = decSubtotal + GetSalesTax()b.) decSubtotal + GetSalesTax(decSubtotal)c.) decTotal = decSubtotal + GetSalesTax(decSubtotal)d.) decTotal = decSubtotal + GetSalesTax(decSubtotal As Decimal)
Answer:
Option C: decTotal = decSubtotal + GetSalesTax(decSubtotal)
Explanation:
To get sales tax, we need a function can process a subtotal amount and return the tax values. By presuming GetSalesTax() is a function that will return a tax value, this function will expect decSubtotal as the input parameter to the function. Otherwise, there will be no values processed in the function.
The statement decTotal = decSubtotal + GetSalesTax(decSubtotal) will invoke function GetSalesTax() by passing decSubtotal as argument. Next the return value of the function will be added with decSubtotal and the summation amount assigned to the variable decTotal.

The nth harmonic number is defined non-recursively as: 1 +1/2 + 1/3 + 1/4 + ... + 1/n. Come up with a recursive definition and use it to guide you to write a function definition for a double -valued function named harmonic that accepts an int parameters n and recursively calculates and returns the nth harmonic number. this is for myprogramminglab.com this is what i have double harmonic(int n) { int sum =0; if (n>0) { sum=sum+(1/(harmonic( n-1))); } return sum; }
Answer:
See the code below.
Explanation:
The nth armonic number is obtained from the following induction process:
[tex]a_1 = 1[/tex]
[tex]a_2 = 1+\frac{1}{2}=a_1 +1[/tex]
[tex]a_3 = 1+\frac{1}{2}+\frac{1}{3}=a_2 +1[/tex]
And for the the n term we have this:
[tex]a_{n-1}=1+\frac{1}{2}+\frac{1}{3}+....+\frac{1}{n-1}[/tex]
[tex] a_n = 1+\frac{1}{2}+\frac{1}{3}+......+\frac{1}{n}=a_{n-1}+\frac{1}{n}[/tex]
In order to create a code for the ne term we can use the following code using python:
# Code to find the nth armonic
# Function to find n-th Harmonic Number
def armonicseries(n) :
# a1 = 1
harmonic = 1
# We need to satisfy the following formulas:
# an = a1 + a2 + a3 ... +..... +an-1 + an-1 + 1/n
for i in range(2, n + 1) :
harmonic += 1 / i
return harmonic
##############################
And then with the following instructions we find the solution for any number n.
n = 3 # thats the number of n that we want to find
print(round(armonicseries(n),5))
Recursive functions are functions that execute itself from within.
The harmonic sum function in Python, where comments are used to explain each line is as follows:
#This defines the function
def harmonic_sum(n):
#This returns 1, if n is less than 2
if n < 2:

On the Loan worksheet, in cell C9, enter a PMT function to calculate the monthly payment for the Altamonte Springs 2022 facilities loan. Ensure that the function returns a positive value and set the references to cells B5 and B6 as absolute references.
Answer:
Microsoft Excel, pmt function.
Explanation:
Microsoft Excel is a spreadsheet application used to manipulate and analyse data. It has several functions and tools to work with. An excel workbook can contain multiple worksheets. It has columns (or field) labelled alphabetically and also numbered rows ( or record).
The PMT function is a financial function used to calculate the periodic payment of loans. It's syntax is;
=PMT(interest rate increase, loan period, loan amount).
For example, if the interest rate increase is annual, and the value is a cell B7, the input would be B7/12. If the value of the loan period and amount are referenced in cells B6 and B5 respectively, the function would be ;
=PMT(B7/12, B6, B5).
But this will give a negative result. For positive result;
=PMT(B7/12, B6, -B5)
Now to make excel pick values from a specified group of cells, they are made absolute by adding the '$' to the columns and rows.
=PMT($B$7/12, $B$6, -$B$5).
The result would positive values spanning to twelve months with interest rate.
To calculate a loan's monthly payment in Excel using the PMT function, enter '=PMT($B$5/12, B6*12, -B4)' in cell C9. This will yield a positive value for the monthly payment with the annual interest rate and loan term set as absolute references.
To calculate the monthly payment for the Altamonte Springs 2022 facilities loan, you need to use the PMT function in Excel. Follow these steps:
Click on cell C9 to make it active.Enter the formula: =PMT($B$5/12, B6*12, -B4), where $B$5 refers to the annual interest rate, B6 to the term in years, and B4 to the loan amount. Using absolute references for $B$5 and $B$6 ensures these references do not change if the formula is copied elsewhere.Press Enter to see the calculated monthly payment displayed as a positive value.Remember, the PMT function helps manage financial calculations efficiently in Excel, ensuring accurate loan payments computations.

A. HTTP
B. TCP/IP
C. DNS
D. HTML
Answer:
The correct answer to the following question will be C. DNS.
Explanation:
DNS stands for Domain Name System, users able to find any information with the help of the domain name. Each and every device which are connected to the internet has there owned IP address, DNS is a system used to translate the domain names into the IP address so it will find the information or browsers can load the resources of the internet.
So by entering the domain name instead on an IP address can also browse the information for any user. And other options like HTTP (Hypertext transfer protocol), HTML (Hypertext markup language) and TCP/IP (Transmission control protocol / Internet protocol) can't help any user for accessing the work done by the DNS.
