What are the advantages of using a database management system (DBMS) over using file-based data storage?

Answer:

A security stance that allows all communications except those prohibited by specific deny exceptions

A plan to restore the mission-critical functions of the organization once they have been interrupted by an adverse event

A security guideline, procedure, or recommendation manua

lAn administrative rule whereby no single individual possesses sufficient rights to perform certain actions

Answer:

it is your answer

Explanation:

it is the storage space where data is kept.

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.

Explanation:

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.

Answer:

Normalization

Explanation:

From the options given :

Boxplot is a data visualization techniqye used for representing numerical data in the form of a box such that it adequately conveys the five number summary if the dataset which are the minimum, maximum, lower quartile, median and upper quartile, it also depicts the presence of outlines.

Scatter plot are used depict the relationship between two variables on the x and y axis of a graph. Each point is a representation of the (x, y) value pairs of the observation.

Tag clouds are usually used to represent word, metatdata and other free form text using different colors and font sizes to give information about the data.

Normalization is the odd option out as it is used to restructure data in other to promote integrity of data.

Answer:

def main():

   # input

   num1 = int(input("Type in a number: "))

   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.

Have a good day!

Answer:

a high speed central network that connects other networks in a distance spanning up to several miles.

Explanation:

A backbone network functions just like the human backbone providing support for network systems by offering a network infrastructure that allows small, high speed internet connectivity. It is a principal data route between large interconnected networks which offers connection services spanning several miles. Most local area networks are able to connect to the backbone network as it is the largest data connection on the internet. This backbone networks are mainly utilized by large organizations requiring high bandwidth connection.

D. Excessive disk space consumption due to storing large documents.

Explanation:

When a company is planning to use NAFDs in its office rather than paper work, the efficiency of employees will increase as unnecessary paper work takes time in handling and printing. When data is stored on disks there is a risk that employees store large or irrelevant files in the disk which will create storage issues.

#SPJ9

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))

Total Cost Cost Driver Square Feet Number of employees Janitorial $150,000 square footage serviced 200 Cafeteria 50,000 Number of employees 20,000 Cutting 1,125,000 4,000 120 Assembly 1,100,000 16,000 The Janitorial and Cafeteria departments are support departments Samoa uses the sequential method to allocate support department costs, first allocating the costs Department to the Cafeteria, Cutting and Assembly departments Determine the proportional (percentage) usage of the Janitorial Department by the a. 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

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)

Answer:

The program is as follows:

float x

float y

float z

x = Get next input

y = Get next input

z = Get next input

Put RaiseToPower(x,y) to output with 5 decimal places

Put "\n" to output

Put RaiseToPower (x,RaiseToPower (y,z)) to output with 5 decimal places

Put "\n" to output

Put AbsoluteValue(x) to output with 5 decimal places

Put "\n" to output

Put SquareRoot(RaiseToPower (x * y,z)) to output with 5 decimal places

Explanation:

This declares all variables

float x

float y

float z

This gets input for all variables

x = Get next input

y = Get next input

z = Get next input

This prints x^y

Put RaiseToPower(x,y) to output with 5 decimal places

This prints a new line

Put "\n" to output

This prints x^(y^z)

Put RaiseToPower (x,RaiseToPower (y,z)) to output with 5 decimal places

This prints a new line

Put "\n" to output

This prints |x|

Put AbsoluteValue(x) to output with 5 decimal places

This prints a new line

Put "\n" to output

This prints sqrt((x * y)^z)

Put SquareRoot(RaiseToPower (x * y,z)) to output with 5 decimal places

Answer:

The program is as follows:

def get_price(fruits):

   AllPrice = fruits.values()

   value_iterator = iter(AllPrice)

   mostExpensive = next(value_iterator)  

   for item in fruits:

       if fruits[item]>=mostExpensive:

           mostExpensive = fruits[item]

           fruitName = item

   print(fruitName)

fruits = {}

n = int(input("Number of Fruits: "))

for i in range(n):

   name = input("Fruit name: ")

   price = int(input("Fruit price: "))

   fruits[name] = price

get_price(fruits)

Explanation:

This defines the get_price function

def get_price(fruits):

This gets all price in the dictionary fruit

   AllPrice = fruits.values()

This passes the values to a value iterator

   value_iterator = iter(AllPrice)

This initializes mostExpensive to the first price in the dictionary

   mostExpensive = next(value_iterator)

This iterates through the elements of the dictionary  

   for item in fruits:

If current element is greater than or equals most expensive

       if fruits[item]>=mostExpensive:

Set most expensive to the current element

           mostExpensive = fruits[item]

Get the corresponding fruit name

           fruitName = item

Print fruit name

   print(fruitName)

The main begins here

This initializes the fruit dictionary

fruits = {}

This gets input for the number of fruits

n = int(input("Number of Fruits: "))

This is repeated for every inputs

for i in range(n):

Get fruit name

   name = input("Fruit name: ")

Get fruit price

   price = int(input("Fruit price: "))

Append name and price to dictionary

   fruits[name] = price

Call the get_price function

get_price(fruits)
