Answer:
Linux is an operating system made up of free software, which can be installed and run on a wide variety of computer systems, from small devices such as mobile phones to large computer systems and supercomputers.
Linux is often offered to the user in various Linux distributions. A characteristic of the distributions is the great possibility of customization and selection that they offer since each one is aimed at a different type of user. Depending on the philosophy, each distribution can provide a greater foundation for ease of use, multimedia applications, ease of configuration, system simplicity, only free software, low resource requirements, and more.
Because of its low cost, high configurability and availability on various platforms, Linux is becoming increasingly popular not only among specialized users, but also among domestic users.
Suppose you were charged with putting together a large LAN to support IP telephony (only) and that multiple users may want to carry on a phone call at the same time. Recall that IP telephony digitizes and packetizes voice at a constant bit rate when a user is making an IP phone call. How well suited are these four protocols for this scenario
Answer:
TDMA: Time-division multiple access (TDMA) will operate effectively.
CSMA: Carrier-sense multiple access (CSMA) will NOT operate properly.
Slotted Aloha: Slotted Aloha will NOT perform effectively.
Token passing: Token passing will operate effectively.

Note: This question is not complete. The complete question is therefore provided before answering the question as follows:
Suppose you were charged with putting together a LAN to support IP telephony (only) and that multiple users may want to carry on a phone call at the same time. Recall that IP telephony digitizes and packetizes voice at a constant bit rate when a user is making an IP phone call. How well suited are these four protocols for this scenario?
TDMA:
CSMA:
Slotted Aloha:
Token passing:
Provide a brief explanation of each answer.
The explanation of the answers is now provided as follows:
TDMA: Time-division multiple access (TDMA) will operate effectively in this situation because it provides a consistent bit rate service of one slot every frame.
CSMA: Because of collisions and a changing amount of time to access the channel, Carrier-sense multiple access (CSMA) will NOT operate properly in this situation. Also, the length of time it takes to access a channel is not limited.
Slotted Aloha: Just like CSMA, Slotted Aloha will NOT perform effectively in this situation because of collisions and a different amount of time to access the channel. Also, the length of time it takes to access a channel is limitless.
Token passing: Token passing will operate effectively in this case because each station has a turn to transmit once per token round, resulting in a service with an effectively constant bit rate.

Brandon has configured one of the applications hosted on his cloud service provider to increase the number of resources as needed. Which of the following describes this capability?
a. Continuity
b. Adaptability
c. Vertical scaling
d. Horizontal scaling
Answer:
The description of this capability is:
d. Horizontal scaling
Explanation:
The capability that Brandon has achieved is horizontal scaling, which involves the increasing of the resources of cloud applications to meet his increasing demand for cloud services. Vertical scaling involves the addition or subtraction of power to a cloud server, which practically upgrades the memory, storage, or processing power. But to scale horizontally, more resources are added or subtracted. The purpose of horizontal scaling is to spread out or in the workload of existing resources and either increase or decrease overall performance and capacity.
Write a program that will generate a personalized invitation within a text file for each guest in the guest list file using the event information found in the event details file. Put all the generated invitation files in a directory called invitations. Ensure that the name of each invitation file uniquely identifies each guest's invitation
Answer:
Code:
import os # os module to create directory
event_file = open("event_details.txt", "r") # Getting event file
event_details = "" # event details to be stored
for row in event_file: # traversing through the event_file
event_details += row # appending event details
os.mkdir("./invitations") # make directory in the same parent directory
names = open("guest_list.txt", "r") # getting names of the people
for name in names: # traversing through names in guest_list file
name = name.replace('\n', '') # removing the ending '\n' from the name
invitation_msg = "Hi! " + name + ", You are heartly invited in the Ceremony.\nAt " + event_details # Generating the invitation message
file_name = '_'.join(name.split(' ')) # Spliting name in space and joining with the '_'
file_path = "./invitations/" + file_name + ".txt" # Generating each file path
invite_file = open(file_path, "w") # Creating the file for each name
invite_file.write(invitation_msg) # Write invitation to file

Write a Python program stored in a file q1.py to play Rock-Paper-Scissors. In this game, two players count aloud to three, swinging their hand in a fist each time. When both players say three, the players throw one of three gestures: Rock beats scissors Scissors beats paper Paper beats rock Your task is to have a user play Rock-Paper-Scissors against a computer opponent that randomly picks a throw. You will ask the user how many points are required to win the game. The Rock-Paper-Scissors game is composed of rounds, where the winner of a round scores a single point. The user and computer play the game until the desired number of points to win the game is reached. Note: Within a round, if there is a tie (i.e., the user picks the same throw as the computer), prompt the user to throw again and generate a new throw for the computer. The computer and user continue throwing until there is a winner for the round.
Answer:
The program is as follows:
import random
print("Rock\nPaper\nScissors")
points = int(input("Points to win the game: "))
player_point = 0; computer_point = 0
while player_point != points and computer_point != points:
computer = random.choice(['Rock', 'Paper', 'Scissors'])
player = input('Choose: ')
if player == computer:
print('A tie - Both players chose '+player)
elif (player.lower() == "Rock".lower() and computer.lower() == "Scissors".lower()) or (player.lower() == "Paper".lower() and computer.lower() == "Rock".lower()) or (player == "Scissors" and computer.lower() == "Paper".lower()):
print('Player won! '+player +' beats '+computer)
player_point+=1
else:
print('Computer won! '+computer+' beats '+player)
computer_point+=1
print("Player:",player_point)
print("Computer:",computer_point)
Explanation:
This imports the random module
import random
This prints the three possible selections
print("Rock\nPaper\nScissors")
This gets input for the number of points to win
points = int(input("Points to win the game: "))
This initializes the player and the computer point to 0
player_point = 0; computer_point = 0
The following loop is repeated until the player or the computer gets to the winning point
while player_point != points and computer_point != points:
The computer makes selection
computer = random.choice(['Rock', 'Paper', 'Scissors'])
The player enters his selection
player = input('Choose: ')
If both selections are the same, then there is a tie
if player == computer:
print('A tie - Both players chose '+player)
If otherwise, further comparison is made
elif (player.lower() == "Rock".lower() and computer.lower() == "Scissors".lower()) or (player.lower() == "Paper".lower() and computer.lower() == "Rock".lower()) or (player == "Scissors" and computer.lower() == "Paper".lower()):
If the player wins, then the player's point is incremented by 1
print('Player won! '+player +' beats '+computer)
player_point+=1
If the computer wins, then the computer's point is incremented by 1
else:
print('Computer won! '+computer+' beats '+player)
computer_point+=1
At the end of the game, the player's and the computer's points are printed
print("Player:",player_point)
print("Computer:",computer_point)

Write a program that solves the following problem:
One marker costs 80 cents. A package of five markers costs $3.50. This encourages people to buy complete packages rather than having to break packages open. The tax is 6.5% of the total. The shipping cost is 5% of the total (before tax). Your program will prompt for a number of markers (an integer). It will calculate and display:
⢠The number of complete packages of markers
⢠The number of separate markers (hint: use // and %)
⢠The cost for the markers before shipping and tax
⢠The cost of shipping
⢠The cost of tax
⢠The total cost of the markers after shipping and tax are added (the grand total)
Answer:
def main():
singleMarkerPrice = 0.80
packageOfMarkersPrice = 3.50
tax = 0.065
shipping = 0.050
userInput = int(input("How many markers do you want? "))
amountOfPackages = 0
singleMarkers = 0
if userInput % 5 == 0:
amountOfPackages = userInput / 5
else:
amountOfPackages = userInput // 5
singleMarkers = userInput % 5
# Just for syntax so if the single marker amount is one, it prints package instead of packages
if amountOfPackages == 1:
print("You have " + str(int(amountOfPackages)) + " complete package")
else:
print("You have " + str(int(amountOfPackages)) + " complete packages")
# Just for syntax so if the single marker amount is one, it prints marker instead of markers
if singleMarkers == 1:
print("You have " + str(int(singleMarkers)) + " single marker")
else:
print("You have " + str(int(singleMarkers)) + " single markers")
totalAmountBeforeTax = (amountOfPackages * packageOfMarkersPrice) + (singleMarkers * singleMarkerPrice)
print("The total amount before tax comes out to " + str(float(totalAmountBeforeTax)))
costOfShipping = float(round((totalAmountBeforeTax * shipping), 2))
costOfTax = float(round((totalAmountBeforeTax * tax), 2))
print("The cost of shipping is " + str(costOfShipping))
print("The cost of tax is " + str(costOfTax))
totalAmount = totalAmountBeforeTax + costOfShipping + costOfTax
print("The total amount comes out to " + str(round(totalAmount, 2)))

What happens when a dataset includes records with missing data?
Answer:
However, if the dataset is relatively small, every data point counts. In these situations, a missing data point means loss of valuable information. In any case, generally missing data creates imbalanced observations, cause biased estimates, and in extreme cases, can even lead to invalid conclusions.
It makes data analysis to be more ambiguous and more difficult.
Missing data is simply the same as saying that there are values and information that are unavailable. This could be due to missing files or unavailable information.
A dataset set with missing data means more work for the analyst. There needs to be a transformation in those fields before the dataset can be used.
Generally speaking missing data could lead to bias in the estimation of data.
A data scientist is a data expert who is in charge of data. He performs the job of data extraction, data analysis, data transformation.

Cafeteria Department b. Cutting Department c. Assembly Department
Answer:
Samoa Industries
Proportional (percentage) usage of the Janitorial Department:
Cafeteria = 50%
Cutting = 10%
Assembly = 40%
Explanation:
a) Data and Calculations:
Total Cost Cost Driver Square Feet Number of
employees
Janitorial $150,000 Square footage serviced 200 40
Cafeteria 50,000 Number of employees 20,000 12
Cutting 1,125,000 4,000 120
Assembly 1,100,000 16,000 40
Proportional (percentage) usage of the Janitorial Department:
Cafeteria = 50% (20,000/40,000 * 100)
Cutting = 10% (4,000/40,000 * 100)
Assembly = 40% (16,000/40,000 * 100)
Cost Allocation of the Janitorial Department:
Cafeteria = 50% * $150,000 = $75,000
Cutting = 10% * $150,000 = 15,000
Assembly = 40,% * $150,000 = 60,000
Total = $150,000
Consider the following generalization of the Activity Selection Problem: You are given a set of n activities each with a start time si , a finish time fi , and a weight wi . Design a dynamic programming algorithm to find the weight of a set of non-conflicting activities with maximum weight.
Answer:
Assumption: Only 1 job can be taken at a time
This becomes a weighted job scheduling problem.
Suppose there are n jobs
Sort the jobs according to fj(finish time)
Define an array named arr to store max profit till that job
arr[0] = v1(value of 1st job)
For i>0. arr[i] = maximum of arr[i-1] (profit till the previous job) or wi(weight of ith job) + profit till the previous non-conflicting job
Final ans = arr[n-1]
The previous non-conflicting job here means the last job with end timeless than equal to the current job.
To find the previous non-conflicting job if we traverse the array linearly Complexity(search = O(n)) = O(n.n) = O(n^2)
else if we use a binary search to find the job Complexity((search = O(Logn)) = O(n.Log(n))

num2 = int(input("Type in another number: "))
num3 = int(input("Type in another number: "))
list1 = [num1, num2, num3]
# sorts the array
list1.sort()
# list1[-1] prints the first element in the array
print("The largest number is: " + str(list1[-1]))
# -len(list1) takes the length of the list, in this case 3, and makes it a negative number.
# That negative number is then used as an index for the list1 array in order to print the lowest number.
print("The smallest number is: " + str(list1[-len(list1)]))
main()
Explanation:
Hope this helped :) I left some comments so you know what's going on. You can also use max(list1) and min(list1) but I chose indexing because indexing is the better way of doing stuff like this.
