Answer:
Network Operating System (NOS)
Explanation:
A network operating system (NOS) is an operating system that makes different computer devices connect to a common network in order to communicate and share resources with each other using a server. A network operating system can be used by printers, computers, file sever among others, and they are connected together using a local area network. This local area network which they are connected to works as the server.
The NOS also acts as a network security because it could be used as an access control or even user authentication.
There are two types of NOS
1) Peer to peer network operating system.
2) Client/server network operating system
A network operating system (NOS) is a server-based operating system oriented to computer networking and may include directory services, network management, network monitoring, network policies, user group management, network security, and other network-related functions.
You have recently resolved a problem in which a user could not print to a particular shared printer by upgrading her workstation's client software. Which of the following might be an unintended consequence of your solution?
a. The user complains that word-processing files on her hard disk take longer to open.
b. The user is no longer able to log on to the network.
c. The shared printer no longer allows users to print double-sided documents.
d. The shared printer no longer responds to form-feed commands from the print server.
Answer:
B - The user is no longer able to log on to the network
Explanation:
Create a Python program that: Allows the user to enter a person's first name and last name. The user should be able to enter as many names as they desire. Create a function that takes the first name and last name, puts them together with the last name first, followed by the first name; with the names separated by commas. Take the result from the function, and place the resulting name in a list. Once the user finishes entering names, sort the contents of the list. Write the sorted names from a list into a text file. When you create the text file, allow the user to enter a name for the file to be created. After you finish writing names to the file, close the file and end the program.
Answer:
#main function start
def main():
#list to store names entered by user
name_list=[]
#variable to take input from user to keep rotating the loop and take input from user again and again
ch='y'
fname=""
lname=""
while ch=='y' or ch=='Y':#keep the loop taking input from user till user do not want to enter more
#take input from user
name=[]
fname=input("Enter first name: ")
lname=input("Enter last name: ")
name.append(fname)
name.append(lname)
#append the previously input first and last name in main list
name_list.append(name)
ch=input("Do you want to continue: (y/Y for yes)")
#main function end
#get file name from user
filename=input("Enter output file name")
#open file in write mode
file=open(filename,"w")
#keep loop add data in file till main list 'name_list' have
for i in name_list:
#Write data in file
file.write("%s, %s\r\n" % (i[0],i[1]))
#close the file
file.close()
#call main function
main()

Account Balance Design a hierarchy chart or flowchart for a program that calculates the current balance in a savings account. The program must ask the user for:________.
A- The starting balance
B- The total dollar amount of deposits made
C- The total dollar amount of withdrawals made
D- The monthly interest rate
Once the program calculates the current balance, it should be displayed on the screen.
Answer:
a. starting balance
Explanation:
A program that calculates the current balance of a savings should ask the user for the starting balance and then ask for the annual interest rate. A loop should then iterate once for every month of the savings period in order to perform other tasks such as asking the user for the total amount deposited into the account, the total amount withdrawn from the account, and calculate the interest rate. The program will then proceed to display the result at the end of the savings period.
Write a program that lets the Michigan Popcorn Company keep track of their sales for seven different types of popcorn they produce: plain, butter, caramel, cheese, chocolate, turtle and zebra. It should use two parallel seven-element arrays: an array of strings that holds the seven popcorn names and an array of integers that holds the number of bags of popcorn sold during the past month for each popcorn flavor. The names should be stored using an initialization list at the time the flavors array is created. The program should prompt the user to enter the number of bags sold for each flavor. Once the popcorn data has been entered, the program should produce a report for each popcorn type, total sales, and the names of the highest selling and lowest selling products. Be sure to include comments throughout your code where appropriate. Complete the C++ code using Visual Studio or Xcode, compress (zip) and upload the entire project folder to the Blackboard assignment area by clicking on the Browse My Computer button or by dragging the file inside the Attach Files box g
Answer:
#include <iostream>using namespace std;int main(){ // declare and initialize popcorn name array string popcorn_name[7] = {"plain", "butter", "caramel", "cheese", "chocolate", "turtle", "zebra"}; // declare and initialize sales array with 7 elements int sales[7]; // A loop to prompt user to enter sales for each popcorn for(int i=0; i < 7; i++){ cout<<"Enter number of sales for " + popcorn_name[i] + " :"; cin>>sales[i]; } // Find maximum sales int max = sales[0]; int maxIndex = 0; for(int j=1; j < 7; j++){ if(max < sales[j]){ max = sales[j]; maxIndex = j; } } // Find minimum sales int min = sales[0]; int minIndex = 0; for(int k=1; k < 7; k++){ if(min > sales[k]){ min = sales[k]; minIndex = k; } } // Print popcorn name and sales for(int l=0; l < 7 ; l++){ cout<<popcorn_name[l]<<"\n"; cout<<"Sales: "<< sales[l]<<"\n\n"; } // Print popcorn name with maximum and minimum sales cout<<"Highest selling: "<< popcorn_name[maxIndex]<<"\n"; cout<<"Lowest selling: "<<popcorn_name[minIndex]<<"\n"; return 0;}Explanation:
Create two arrays to hold the list of popcorn name and their sales (Line 5-8). Next prompt user to input the sales for each popcorn (Line 10-14). Get the maximum sales of the popcorn (Line 17-24) and minimum sales (Line 27-34). Print the popcorn name and sales (Line 37-40) and the popcorn name with highest and lowest selling (Line 43-44).
A new operating system uses passwords that consist of three characters. Each character must be a digit between 0 and 9. For example, three distinct possible passwords are 123, 416, and 999. The system uses 32-bit salt values. The system also allows one login attempt every second and never locks out users regardless of how many failed attempts occur. If an adversary has obtained a copy of the password file and conducts an offline brute-force attack by trying every password combination until the adversary obtains username and password combination. The use of a 32-bit salt value
Answer:
Brute force is technique that is used for cracking password
In this case the system uses only three characters(0-9). By applying Brute force attack in "hit and try" manner we easily crack the password.
Explanation:
Solution
There are a wide variety of password cracking mechanisms.Brute force is one of the popular password cracking technique.Brute force attack is generally used to crack small passwords.
In the given example the system uses only three characters(0-9).By using Brute force attack in "hit and try" manner we easily crack the password.There are only 10 possible passwords for this type of system.Because we can arrange 0-9 only in 10 ways.But for Systems with long passwords it is difficult to find it in hit and try manner.But instead of having plain password each password have a random salt value.
In a system of 32 bit salt value there are 2^32 different key values.
By increasing the salt value from 32 bits to 64 bits there are 2^64 different key values.It increases the time taken to crack a password for an attacker.so by changing salt value from 32 to 64 bits will make it more harder for the adversary's attack to be successful.

phishingransomwaredenial of servicemain in the middleSQL injectionmalwareWrite a program in python that can compare the unit (perlb) cost of sugar sold in packages with different weights and prices. The program prompts the user to enter the weight and price of package 1, then does the same for package 2, and displays the results to indicate sugar in which package has a better price. It is assumed that the weight of all packages is measured in lb. The program should check to be sure that both the inputs of weight and price are both positive values.
Answer:
weight1 = float(input("Enter the weight of first package: "))
price1 = float(input("Enter the price of first package: "))
weight2 = float(input("Enter the weight of second package: "))
price2 = float(input("Enter the price of second package: "))
if weight1 > 0 and price1 > 0 and weight2 > 0 and price2 > 0:
unit_cost1 = price1 / weight1
unit_cost2 = price2 / weight2
if unit_cost1 < unit_cost2:
print("Package 1 has a better price.")
else:
print("Package 2 has a better price.")
else:
print("All the entered values must be positive!")
Explanation:
*The code is in Python.
Ask the user to enter the weight and the price of the packages
Check if the all the values are greater than 0. If they are, calculate the unit price of the packages, divide the prices by weights. Then, compare the unit prices. The package with a smaller unit price has a better price.
If all the entered values are not greater than 0, print a warning message

There's nothing wrong with the question you posted except that it's not well presented or arranged.
When properly formatted, the program will be error free and it'll run properly.
The programming language used in the question is Java programming lamguage.
in java, the sign ";" signifies the end of each line and lines that begins with // represent comments. Using this understanding of end of lines and comments, the formatted code goes thus
import java.util.Scanner;
public class Arraysum {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
final int NUM_ELEMENTS = 8;
// Number of elements
int[] userVals = new int[NUM_ELEMENTS];
// User numbers
int i = 0;
// Loop index
int sumVal = 0;
// For computing sum
// Prompt user to populate array
System.out.println("Enter " + NUM_ELEMENTS + " integer values...");
for (i = 0; i < NUM_ELEMENTS; ++i) {
System.out.print("Value: ");
userVals[i] = scnr.nextInt();
}
// Determine sum

The new Director of Information Technology has asked you to recommend a strategy to upgrade the servers on their network. Recommendations on server hardware, CPU chip set, speed, and caching are needed. You should also recommend which servers to upgrade first and determine whether any servers are still appropriate to keep.
Answer:
servers to be upgraded are : APPLICATION AND LOAD BALANCING SERVERS
servers still appropriate to use : DNS AND DHCP SERVERS
Explanation:
The recommendations to be made in line with what the new director of information is asking for includes :
1 ) For the servers to be upgraded : The servers that requires upgrades includes the APPLICATION SERVER and LOAD BALANCING SERVER. this is because these two servers are critical to the growth/expansion of any business, and they handle large volume of data
Recommendations on the servers upgrade includes:
Hardware : 2.3 GHz Intel Xeon Gold 5118 12-Core
CPU chip set : Socket: FCLGA3647, Type: NSBM
Speed : processor 3.2 GHz
caching: > 100 Gb
2) For servers that do not necessarily need to be upgraded : The servers that do not need immediate upgrade are DNS and DHCP
Write a function PrintShampooInstructions(), with int parameter numCycles, and void return type. If numCycles is less than 1, print "Too few.". If more than 4, print "Too many.". Else, print "N: Lather and rinse." numCycles times, where N is the cycle number, followed by "Done.". End with a newline. Example output for numCycles = 2:
1: Lather and rinse.
2: Lather and rinse.
Done.
Hint: Define and use a loop variable.
Sample program:
#include
using namespace std;
int main() {
PrintShampooInstructions(2);
return 0;
}
Answer:
public static void PrintShampooInstructions(int numberOfCycles){
if (numberOfCycles<1){
System.out.println("Too Few");
}
else if(numberOfCycles>4){
System.out.println("Too many");
}
else
for(int i = 1; i<=numberOfCycles; i++){
System.out.println(i +": Lather and rinse");
}
System.out.println("Done");
}
Explanation:
I have used Java Programming language to solve this
Use if...elseif and else statement to determine and print "Too Few" or "Too Many".
If within range use a for loop to print the number of times
Answer:
#In Python
def shampoo_instructions(num_cycles):
if num_cycles < 1: ///
print ('Too few.') ///
elif num_cycles > 4:
print ('Too many.')
else:
i = 0
while i<num_cycles:
print (i+1,": Lather and rinse.")
i = i + 1
print('Done.')
user_cycles = int(input())
shampoo_instructions(user_cycles)
Explanation:
def shampoo_instructions(num_cycles): #def function with loop
if num_cycles < 1: #using 1st if statement
print('Too few.')
elif num_cycles > 4:
print ('Too many.')
else:
i = 0
while i<num_cycles:
print (i+1,": Lather and rinse.")
i = i + 1
print('Done.')
user_cycles = int(input())
shampoo_instructions(user_cycles)

Consider the following concurrent tasks, in which each assignment statement executes atomically. Within a task, the statements occur in order. Initially, the shared variables x and y are set to 0.
Task 1 Task 2
x = 1 y = 1
a = y b = x
At the end of the concurrent tasks, the values ofa andb are examined. Which of the following must be true?
I. ( a == 0 ) ( b == 1 )
II. ( b == 0 ) ( a == 1 )
III. ( a == 1 ) ( b == 1 )
(A) I only
(B) II only
(C) III only
(D) I and II only
(E) I, II, and III
Answer:
(D) I and II only
Explanation:
Concurrent tasks is when there is more than one task to be performed but the order of the task is not determined. The tasks occur asynchronously which means multiple processors occur execute input instruction simultaneously. When x =1 and y = 1, the concurrent task will be performed and the a will be zero or either 1.

Write a program that asks the user to enter either an "African" or a "European" swallow. The programâs behaviour should mimic the program below. If the user enters something øther than "African" or "European", the program shøuld insult the user like the example below.
Sample Output #1:
What kind of swallow?
African
Yes, it could grip it by the husk.
Sample Output #2:
What kind of swallow?
European
A five-ounce bird could not carry a one-pound coconut.
Sample Output #3:
What kind of swallow?
Spanish
You really are not fit to be a king.
Answer:
The programming language is not stater; However, I'll answer this question using C++.
This program does not use comments (See explanation)
See Attachment for program file
Program starts here
#include <iostream>
using namespace std;
int main()
{
string response;
cout<<"What kind of swallow?\n";
cin>>response;
for(int i =0; i<response.length();i++)
{
response[i]=toupper(response[i]);
}
if(response == "AFRICAN")
{
cout<<"Yes, it could grip it by the husk.";
}
else if(response == "EUROPEAN")
{
cout<<"A five-ounce bird could not carry a one-pound coconut.";
}
else
{
cout<<"You really are not fit to be a king.";
}
return 0;
}
Explanation:
string response; -> A string variable to hold user input is declared
cout<<"What kind of swallow?\n"; -> prompts user for input
cin>>response; -> user input is stored here
The following iteration converts user input to uppercase; so that the program will work for inputs like African, AFRICAN, AFriCAN, etc.
for(int i =0; i<response.length();i++)
{
response[i]=toupper(response[i]);
}
The following if statement prints "Yes, it could grip it by the husk." if user input is AFRICAN
if(response == "AFRICAN")
{
cout<<"Yes, it could grip it by the husk.";
}
Otherwise, if user input is EUROPEAN, it prints; "A five-ounce bird could not carry a one-pound coconut."
else if(response == "EUROPEAN")
{
cout<<"A five-ounce bird could not carry a one-pound coconut.";
}
Lastly; for every inputs different from AFRICAN and EUROPEAN, the program displays "You really are not fit to be a king."
else
{
cout<<"You really are not fit to be a king.";

Two of the most fundamental functions for dealing with interprocess communication are read() and write(). Consider the following otherwise valid C program:int r, pipeFDs[2];
char message[512];
pid_t spawnpid;
pipe(pipeFDs);
spawnpid = fork();
switch (spawnpid)
{
case 0:
close(pipeFDs[0]); // close the input file descriptor
write(pipeFDs[1], "hi process, this is the STUFF!!", 21);
break;
default:
close(pipeFDs[1]); // close output file descriptor
r = read(pipeFDs[0], message, sizeof(message));
printf("Message received from other: %s\n", message);
break;
}
Select each of the following answers that is correct. CAN BE MULTIPLE CHOICES...
(1) The read() call may block until data becomes available
(2) When the read() call returns, this one call will return all of the data that was sent through the pipe, which is different behavior than if this was a socket
(3) If the read() call blocks, the process will be suspended until data arrives
(4) The write() call will return before all of the data has been written, if the corresponding read() call blocks mid-transfer
(5) Pipes can fill, which will cause the write() call to block until the read() call is able to read data from the pipe
Answer: Provided in the explanation section
Explanation:
int r, pipeFDs[2];
char message[512];
pid_t spawnpid;
pipe(pipeFDs);
spawnpid = fork();
switch (spawnpid)
{
case 0:
close(pipeFDs[0]); // close the input file descriptor
write(pipeFDs[1], "hi process, this is the STUFF!!", 21);
break;
default:
close(pipeFDs[1]); // close output file descriptor
r = read(pipeFDs[0], message, sizeof(message));
printf("Message received from other: %s\n", message);
break;
}
Observation of the program:
The read() call may block until data becomes available If the read() call blocks, the process will be suspended until data arrives Pipes can fill, which will cause the write() call to block until the read() call is able to read data from the pipe⇒ Therefore,Option 1,3 and 5 correct

UC wants to create a sandbox to test its Service Cloud implementation with real Sales Cloud data. Which three Sandbox types can be used to accomplish this? Choose 3 answersA. Administrator SandboxB. Partial Copy SandboxC. Full SandboxD. Developer k Pro SandboxE. Test Sandbox
Answer:
B. Partial Copy Sandbox
C. Full Sandbox
D. Developer k Pro Sandbox
Explanation:
In this scenario Universal containers wants to implement a service cloud and test with real Sales Cloud data.
Service cloud is defined a system that allows automation of various customer service functions. It can listen to customers via different social media platforms and direct customers to agents that can solve their problems.
Sandbox is a testing environment that is isolated and allows for running of programs without affecting the application.
To test service cloud implementation with real data we use the following 3 sandboxes:
- Partial copy sandbox: copies only relevant data to test configurations with real data.
- Full Sandbox: makes a replica of data by copying all data such as attachments, metadata, and object records.
- Developer K pro sandbox: is used by developers to test software in an isolated environment and can use large data sets. It includes configuration data (metadata)
A laptop computer has two internal signals: An unplugged signal, which is '1' if the laptop's power supply is connected, and '0' otherwise. A low battery signal, which is '0' if the laptop's battery has reached an almost empty state, and '1' otherwise. Suppose the laptop's power control system accepts a single hibernate signal which determines if the laptop should change its current operating state and shut down. If the laptop should shut down when the battery is low and its charger is unplugged, which gate could be used to produce the hibernate signal?
Answer:
The correct usage is a NOR gate which is indicated in the explanation.
Explanation:
The truth table for the given two signals, namely
p=unplugged signal
q=low battery signal
can form a truth table of following form
Here p has 2 states
1 if the power supply is connected
0 otherwise
Similarly q has 2 states
0 if the battery has reached almost zero state
1 otherwise
As the condition for the Hibernate Signal is given as to only activate when the battery is low and the power supply is not connected. This indicate that the value of Hibernate signal should be 1 when both p and q are 0.
Using this condition, the truth table is formed as
unplugged signal | low battery signal | Hibernate Signal
0 | 0 | 1
0 | 1 | 0
1 | 0 | 0
1 | 1 | 0
Now the truth table of NOR is given as
a | b | a or b | ~(a or b)
0 | 0 | 0 | 1
0 | 1 | 1 | 0
1 | 0 | 1 | 0
1 | 1 | 1 | 0
This indicates that the both truth tables are same thus the NOR gate is to be used for this purpose.

You are a network technician for a small corporate network that supports 1000 Mbps (Gigabit) Ethernet. The manager in the Executive Office says that his network connection has gone down frequently over the past few days. He replaced his Ethernet cable, but the connection problem has continued. Now his network connection is either down or very slow at all times. He wants you to install a new 1000 Mbps Ethernet network card in his workstation to see if that solves the problem.
If the new card does not resolve the issue, you will need to perform troubleshooting tasks to find the cause of the issue and confirm that the problem is fixed after you implement a solution. Following are some troubleshooting tasks you can try:
• Use the Network and Sharing Center and the ipconfig command on the Exec workstation to check for a network connection or an IP address.
• Look at the adapter settings to see the status of the Ethernet connection.
• Use the ping command to see if the workstation can communicate with the server in the Networking Closet. (See the exhibit for the IP address.)
• View the network activity lights for all networking devices to check for dead connections. In this lab, your task is to complete the following:
1. Install a new Ethernet adapter in one of the open slots in the Exec workstation per the manager's request.
2. Make sure that the new adapter is connected to the wall outlet with a cable that supports Gigabit Ethernet.
3. Resolve any other issues you find using the known good spare components on the Shelf to fix the problem and restore the manager's internet connection.
After you replace the network adapter and resolve the issues you found while troubleshooting, use the Network and Sharing Center to confirm that the workstation is connected to the network and the internet

Answer:
The step by step explanation
Explanation:
Before doing anything, the first thing to do is to select the 100BaseTX network adapter and reconnect the Cat5e cable. The 100BaseTX network adapter supports Fast
Ethernet which is all that is required.
Now do the following steps:
Step one
In Office 2, switch to the motherboard view of the computer (turning off the workstation as necessary).
Step two
On the Shelf, expand the Network Adapters category.
Step three
Identify the network adapter that supports Fast Ethernet 100BaseTX. Drag the network adapter from the Shelf to a
free PCI slot on the computer.
Step four
To connect the computer to the network, switch to the back view of the computer.
Step five
Drag the Cat5 cable connector from the motherboard's NIC to the port of the 100BaseTX network adapter.
Step six
To verify the connection to the local network and the Internet, switch to the front view of the computer.
Step seven
Click the power button on the computer case.
Step eight
After the workstation's operating system is loaded, click the networking icon in the notification area and click
Open Network and Sharing Center. The diagram should indicate an active connection to the network and the
Internet.
For one to be able to confirm the speed of the connection, it can be done by clicking the Local Area Connection link in the Network and
Sharing Center.
Given the array [13, 1, 3, 2, 8, 21, 5, 1] suppose we choose the pivot to be 1 the second element in the array. Which of the following would be valid partitions?
A. 1 [1, 2, 3, 5, 8, 13, 21]
B. 1 [13, 1, 3, 2, 8, 21, 5]
C. 1 [13, 3, 2, 8, 21, 5, 1]
D. [1] 1 [13, 3, 2, 8, 21, 5]
E. [13] 1 [3, 2, 8, 21, 5, 1]
F. [13, 1, 3, 2, 8, 21, 5] 1 2/4
Answer:
D. [1] 1 [13, 3, 2, 8, 21, 5]
Explanation:
Using a quicksort with 1 as the pivot point, elements less than 1 will be sorted to the left of 1 and the other elements are greater than one will be sorted to the right of 1. The order doesn't matter. So we sort [1] to the left of 1 and [13, 3, 2, 8, 21, 5] to the right of 1. So, D. [1] 1 [13, 3, 2, 8, 21, 5] is the valid partition.
If you were required to give a speech identifying the risks of using computers and digital devices, which group of items would you include?
Camera and Mic
These 2 things are the most likely things to get you in trouble. Unless you have a 100% protected device, and honestly even if you do, cover up the camera and close your mic. This will definitely save you later.
Write a program that displays the following pattern: ..\.\* .\.\*** \.\***** ******* \.\***** .\.\*** ..\.\* That is, seven lines of output as follows: The first consists of 3 spaces followed by a star. The second line consists of 2 spaces followed by a 3 stars. The third consists of one space followed by 5 stars, and the fourth consists just of 7 stars. The fifth line is identical to third, the sixth to the second and the seventh to the first. Your program class should be called StarPattern
Answer:
public class StarPattern {
public static final int MAX_ROWS = 7;
public static void main(String []args){
for (int row = 1; row <= MAX_ROWS; row++) {
int numOfSpaces = getNumberOfSpaces(row);
int numOfStars = MAX_ROWS - (getNumberOfSpaces(row) * 2);
String spaces = printSpaces(numOfSpaces);
String stars = printStars(numOfStars);
System.out.println(spaces + stars);
}
}
public static int getNumberOfSpaces(int row) {
int rowOffset = (MAX_ROWS / 2) + 1;
return Math.abs(row-rowOffset);
}
public static String printSpaces(int num) {
String result = "";
for (int i = 0; i < num; i++) {
result += " ";
}
return result;
}
public static String printStars(int num) {
String result = "";
for (int i = 0; i < num; i++) {
result += "*";
}
return result;
}
}
Explanation:
So it sounds we need to make a diamond shape out of asterisks like this:
*
***
*****
*******
*****
***
*
There are 7 rows and each row has up to 7 characters. The pattern is also symmetrical which makes it easier. Before writing any code, let's figure out how we are going to determine the correct amount of spaces we need to print. There are a lot of ways to do this, but I'll just show one. Let's call the 4th row y=0. Above that we have row 3 which would be y=-1, and below is row 5 which is y=1. With 7 rows, we have y=-3 through y=3. The absolute value of the y value is how many spaces we need.
To determine the number of stars, we just double the number of spaces, then subtract this number from 7. This is because we can imagine that the same amount of spaces that are printed in front of the stars are also after the stars. We don't actually have to print the second set of spaces since it is just white space, but the maximum number of characters in a row is 7, and this formula will always make sure we have 7.
I hope this helps. If you need help understanding any part of the code, jsut let me know.
