) Explain why virtualisation and containerisation are indispensable for cloud services provision. (10 marks)

Answers

Answer 1

Virtualization and containerization play a vital role in the provision of cloud services. They help to enhance the effectiveness and efficiency of cloud services provision.

Virtualization is essential in cloud computing since it enables the partitioning of a server or computer into smaller virtual machines. Each of the smaller virtual machines can run different operating systems, which is highly beneficial since the machines can be utilized in a better way. It ensures that the different operating systems do not conflict with each other, hence improving efficiency and reducing the risks of downtime.

Virtualization also enhances cloud security since the hypervisor layer ensures that each virtual machine is isolated from each other, which reduces the risks of unauthorized access. It also ensures that the applications on one virtual machine do not affect the applications running on other virtual machines .Containerization Containerization is a lightweight form of virtualization that operates at the application level.

Write a code in java that will print "Welcome to my shop" Press 1 to add an item Press 2 to exit... Using the switch case function and inheritance method.

Answers

In Java, the switch statement is utilized to execute one of the numerous code blocks depending on the value of a variable. It is used instead of nested if-else statements when a condition is fulfilled.

The switch statement evaluates an expression and executes the corresponding code block. The inheritance technique is used to obtain code reusability in object-oriented programming. It's a method of creating a new class from an existing class. The following Java code uses the switch case function and inheritance method to accomplish the task of printing "Welcome to my shop," prompting the user to "Press 1 to add an item" or "Press 2 to exit."

The program prints "You entered an invalid option" if the user enters anything other than 1 or 2 When the user enters 2, the program exits. If the user enters anything other than 1 or 2, the program displays an error message.The Item class has only one method named add(), which prints "Item added successfully."When the user selects option 1, the Item class's add() function is called, and the message "Item added successfully" is displayed.

Answers

The dynamic programming approach for the smallest product problem involves using the recurrence relation minProd(i) = min(A[i], A[i] ˣ minProd(i - 1)) and implementing bottom-up computation.

(a) What is the recurrence relation for an O(n) time dynamic programming solution to the smallest product problem? (b) Provide pseudocode for an O(n) time bottom-up dynamic programming solution to the smallest product problem.

The smallest product problem involves finding the smallest product of any subarray within a given array of positive real numbers.

To solve this problem efficiently in O(n) time, a dynamic programming approach is utilized.

The recurrence relation minProd(i) = min(A[i], A[i] ˣ minProd(i - 1)) is employed, where minProd(i) represents the minimum product ending at index i.

This relation considers two possibilities: either taking the value at index i alone or multiplying it with the minimum product ending at index i - 1.

By iteratively computing the minimum product at each index and considering all possible subarrays, the algorithm accurately determines the smallest product.

The pseudocode implements a bottom-up dynamic programming solution, initializing an array and iteratively updating its values.

Ultimately, the minimum value in the array is returned as the solution.

True/False:
- HTTP can use either TCP or UDP as its transport layer protocol.
- DNS uses UDP as its transport layer.

Answers

The answers to the questions are as follows:True: HTTP can use either TCP or UDP as its transport layer protocol. This means that the HTTP can be used with either TCP (Transmission Control Protocol) or UDP (User Datagram Protocol) as the transport protocol.

Transmission Control Protocol (TCP) is one of the primary protocols used in the Internet Protocol Suite. It operates at the transport layer and is used to establish a connection between the sender and receiver and to ensure reliable communication. User Datagram Protocol (UDP) is another protocol used at the transport layer.

Unlike TCP, it doesn't establish a connection with the receiving device, but it sends the data packet directly to the recipient.

False: DNS (Domain Name System) uses UDP as its transport layer. DNS uses both UDP and TCP as its transport protocol.

DNS is primarily a UDP-based protocol, meaning that it works best with UDP. DNS can use TCP for the larger DNS responses that can't be handled in a single UDP packet. As a result, UDP is used for quick queries and small responses, while TCP is used for zone transfers and large queries.

−x+2 in decimal form. c) Read an entered time by the user in hours, minutes, and seconds and output the time in seconds (up to 65535). d) Read an inputted string by user (maximum number of characters is 30 ), then find and print the number of occurrences of a character that the user chooses from the inputted string entered earlier by the user.

Answers

Here's a solution written in assembly language for the 8086 Emulator that fulfills the given requirements. The program allows the user to choose from four options: converting a decimal number to octal, evaluating a binary expression, converting time to seconds, or counting occurrences of a character in a string.

The assembly program starts by displaying a menu of options to the user. It then waits for the user to input their choice. Based on the selected option, the program branches to the corresponding subroutine to perform the desired operation.

For option (a), the program prompts the user to enter a decimal number between 0 and 65535. It reads the input and converts it to its octal equivalent using a series of division and remainder operations. The octal value is then printed on the screen.

For option (b), the program prompts the user to enter a positive 8-bit binary number. It reads the input and performs the specified mathematical expression:[tex]y = x^2 - x + 2[/tex]. The result is then printed in decimal form.

For option (c), the program prompts the user to enter a time in hours, minutes, and seconds. It reads the input and converts it to the total number of seconds. This is achieved by multiplying the hours by 3600, the minutes by 60, and then adding the seconds. The resulting total is printed on the screen.

For option (d), the program prompts the user to enter a string with a maximum of 30 characters. It reads the input and prompts the user to enter a character to search for within the string. The program then counts the occurrences of the specified character and displays the count on the screen.

Each subroutine is implemented using appropriate assembly instructions and algorithms to perform the desired operations accurately.

(Cryptography)- This problem provides a numerical example of encryption using a one-round version of DES. We start with the same bit pattern for both the key K and the plaintext block, namely: Hexadecimal notation: 0 1 2 3 4 5 6 7 8 9 A B C D E F
Binary notation: 0000 0001 0010 0011 0100 0101 0110 0111
1000 1001 1010 1011 1100 1101 1110 1111
(a) Derive k1, the first-round subkey (b) Derive L0 and R0 (i.e., run plaintext through IP table) (c) Expand R0 to get E[R0] where E[.] is the Expansion/permutation (E table) in DES

Answers

(a) k1 = 0111 0111 0111 0111 0111 0111 0111 0111

(b) L0 = 0110 0110 0110 0110 0110 0110 0110 0110

   R0 = 1001 1001 1001 1001 1001 1001 1001 1001

(c) E[R0] = 0100 0100 0101 0101 0101 0101 1001 1001

In the first step, we need to derive k1, the first-round subkey. For a one-round version of DES, k1 is obtained by performing a permutation on the initial key K. The permutation results in k1 being equal to the rightmost 8 bits of the initial key K, repeated 8 times. So, k1 = 0111 0111 0111 0111 0111 0111 0111 0111.

In the second step, we derive L0 and R0 by running the plaintext block through the Initial Permutation (IP) table. The IP table shuffles the bits of the plaintext block according to a predefined pattern. After the permutation, the left half becomes L0 and the right half becomes R0. In this case, the initial plaintext block is the same as the initial key K. Therefore, L0 is equal to the leftmost 8 bits of the initial plaintext block, repeated 8 times (0110 0110 0110 0110 0110 0110 0110 0110), and R0 is equal to the rightmost 8 bits of the initial plaintext block, repeated 8 times (1001 1001 1001 1001 1001 1001 1001 1001).

In the third step, we expand R0 to get E[R0] using the Expansion/permutation (E table) in DES. The E table expands the 8-bit input to a 12-bit output by repeating some of the input bits. The expansion is done by selecting specific bits from R0 and arranging them according to the E table. The resulting expansion E[R0] is 0100 0100 0101 0101 0101 0101 1001 1001.

Overview
Write a program that accepts a time from the keyboard and prints the times in simplified form.
Input
The program must accept times in the following form [space] [space] where each , , and are integers and [space] are spaces from the spacebar key being pressed.
Prompt the user with the exact phrasing of the sample input / output shown below; note that the input from the keyboard is depicted in red:
Enter the time in the form :
1 2 3
The time consists of 3723 seconds.
Simplified time: 1:2:3
Requirements
The name of the class that contains the main must be TimeInterpreter.
While input uses spaces between the input numbers, the output format with days, hours, minutes, and seconds should be delimited by colons; see sample output for examples.
All times will be output without spaces (or other whitespace).
Negative Times. If a specified time is negative, it should be printed with a single leading negative. For example, 0 -2 -34 is output as -2:34.
Simplification. Times must be simplified before printed. For example, 12 2 -34 is simplified and output as 12:1:26.
Output Brevity. For input time 0 2 34, the corresponding output should not list the number of hours (since there are none): 2:34.
A single output print statement will be allowed in the final solution code. That is, a proper solution will construct a String object and output it at the end of the program.
You must define and use constants representing the number of seconds per minute, hour, and day.

Answers

In the given code, there is an issue with handling double negatives in the input time. When the seconds or minutes are negative, the code attempts to subtract 60 from them to obtain the correct value. However, instead of subtracting 60, it subtracts 1 from 60, resulting in incorrect output for double negative times. To fix this, the line "minutes = 60 -1;" should be changed to "minutes = 60 - minutes;". This will correctly subtract the negative value of minutes from 60.

The provided code is meant to accept a time input in the format of hours, minutes, and seconds, and then simplify and print the time in the format of days, hours, minutes, and seconds.

However, there is a specific issue with the handling of double negative times. In the code, when the seconds or minutes are negative, the code attempts to calculate the correct value by subtracting 1 from 60. This is incorrect because it should subtract the negative value itself.

To resolve this issue, the line "minutes = 60 -1;" should be modified to "minutes = 60 - minutes;". This change ensures that when minutes are negative, the negative value is subtracted from 60 to obtain the correct positive value.

By making this modification, the code will correctly handle double negative times and produce the expected output.

INSTEAD OF triggers are used when INSERTing values into more than one table Updating views that cannot be updated An action to be taken when a specific event happened An action to be taken when a transaction is aborted

Answers

INSTEAD OF triggers are used in database systems to perform specific actions when certain events occur. These triggers are commonly used in situations where values need to be inserted into multiple tables simultaneously, or when views cannot be directly updated.

When inserting values into multiple tables, INSTEAD OF triggers can be used to ensure that the values are properly distributed across the tables. Instead of executing the default insert operation, the trigger will intercept the insert statement and perform the necessary actions to insert the values into the respective tables.

Similarly, INSTEAD OF triggers are useful when updating views that cannot be directly updated. Views are virtual tables created based on the result of a query, and sometimes they cannot be modified directly. INSTEAD OF triggers allow for the execution of custom actions instead of the default update operation on the view, enabling modifications to be made indirectly.

Additionally, INSTEAD OF triggers can be employed to define actions to be taken when a specific event occurs, such as when a particular condition is met or when a transaction is aborted. These triggers provide flexibility in specifying the desired behavior in response to various events, allowing for customized actions to be taken in different scenarios.

Overall, INSTEAD OF triggers offer a mechanism to control and customize the actions performed in response to events, whether it involves inserting values into multiple tables, updating non-updatable views, or handling specific events and transaction outcomes.

Explain the different kind of localities in parallel algorithmic design? What is meant by pipelining?

Answers

Localities in parallel algorithmic design refer to different ways in which data is distributed and accessed by processors in a parallel computing system. Pipelining is a technique used in parallel processing to increase the efficiency of data processing by overlapping the execution of multiple tasks.

What are the different kinds of localities in parallel algorithmic design?

In parallel algorithmic design, different kinds of localities include data locality and task locality.

Data locality refers to how data is distributed and accessed by processors. There are two main types of data locality:

Spatial Locality: It refers to the principle that data elements that are stored close to each other in memory are likely to be accessed together. This locality is leveraged by partitioning data into blocks and assigning each block to a processor.

Temporal Locality: It refers to the principle that data elements that are accessed recently are likely to be accessed again in the near future. This locality is exploited by using data caching techniques to store frequently accessed data closer to the processors.

Task locality refers to how tasks or computations are assigned to processors. There are two main types of task locality:

Static Task Locality: It involves partitioning the overall computation into static tasks and assigning each task to a specific processor. This approach is suitable for problems with known and fixed task sizes.

Dynamic Task Locality: It involves dynamically assigning tasks to processors based on workload distribution and load balancing techniques. This approach is beneficial for problems with varying task sizes or dynamically changing workloads.

This has been fixed.The command `plt.cla()` has been removed because it clears the current axis, which is not needed in this case.The `%recall 5` and `%recall 6-13` commands have been removed because they are not needed.The `plt.show()` command has been added to display the plot.The corrected code generates a bar plot showing the frequencies of each value when a six-sided die is rolled. The x-axis shows the die values, and the y-axis shows the frequency of each value. The frequencies are displayed above each bar in the plot.

The title of the plot shows the number of times the die was rolled. The xlabel and ylabel show the labels for the x-axis and y-axis, respectively. The ylim command sets the upper limit of the y-axis to 10% more than the maximum frequency. The seaborn module is used to set the style of the plot to whitegrid. The palette parameter is used to set the color of the bars in the plot. The zip function is used to iterate over each bar and its corresponding frequency in the for loop.

Answers

To solve the given question, we need to write a program that inserts a new customer into an existing file, "customers.txt," while ensuring that no customer number appears more than once.

In order to accomplish this task, we can follow these steps:

Declare a structure named "entry" with two members: a character array "name" of size 15 and an integer variable "customer number".Prompt the user to enter the name and customer number for the new customer using the keyboard.Open the "customers.txt" file in append mode, checking for any errors in the file opening process.Read the existing entries from the file one by one and compare each customer number with the new customer number. If a match is found, display an error message indicating that the customer number already exists and exit the program.If no match is found, write the new customer's details to the file.Close the file, checking for any errors in the file closing process.

This program ensures that the customer numbers are unique in the "customers.txt" file and handles any errors that may occur during file operations.

In this program, we use a structure to define the format of each customer entry, which consists of a name and a customer number. The program prompts the user to enter the name and customer number for the new customer, and then opens the "customers.txt" file in append mode. It reads the existing entries from the file and checks if the new customer number already exists. If a match is found, an error message is displayed, and the program terminates. Otherwise, it writes the new customer's details to the file. Finally, the file is closed, and any errors during the file operations are handled.

Instead, respond to the following prompt by using economic terms/concepts from the textbook. You can use your own experience to reflect how the articles relate to the chapter from the book and copy terms from the book. However, whenever you copy something exactly word by word, make sure you put parenthesis for example, "words".Relate the following article(s) to the law of supply and demand.Ford shuts factories over tire crisisFord Motor company is to temporarily close three US truck assembly plants temporarily to help it deal with the Bridgestone/Firestone tire crisis.The car giant said that 70,000 tires which were due for use on Ford Explorers and Mercury Mountaineers would be diverted to dealerships to replace faulty Bridgestone tires. The three plants will close for two weeks from 28 August, with the result that 25,000 trucks will be cut from Ford's third quarter production schedule.Senior vice president Martin Inglis said: "Clearly this will impact earnings." Ford will be able to recoup most of the lost production of the 2001 Ford Ranger - about 10,000 units - during the remainder of the year. But lost production of about 15,000 2001 Ford Explorers, at the centre of the recall, will be pushed into next year, he said. The recall earlier this month of 6.5 million Bridgestone/Firestone tires was prompted by safety fears.Workers paid The move has created a nationwide shortage, with the plant shutdowns seen as a way of speeding its resolution. The recall came as the US National Highway Traffic Safety Administration investigates the tires in connection with 62 deaths and more than 100 injuries.The tires in question were mounted mostly on Ford trucks and sports utility vehicles, including the Explorer. The 15-inch tires at the three plants were earmarked for use on new vehicles, but will now be sent to dealers and installed on existing Ford trucks and sports utility vehicles. The plants employ about 6,000 workers, who will be paid during the shutdown.

For the taxation year ending December 31, 2021, Dinho Inc. has Taxable Income, before consideration of dividends or salary paid to its sole shareholder, of $130,000. The Company's cash balance, prior to the payment of any salary or dividends is $130,000. The Company is subject to a combined federal/provincial tax rate of 12 percent on all of its Taxable Income for 2021. Alfred Dinho, the sole shareholder of Dinho Inc., has significant amount of employment income, and because of this, any additional income will be taxed at a combined federal/provincial rate of 49 percent. The provincial dividend tax credit is equal to 20 percent of the gross up for non-eligible dividends. Required: Mr. Dinho has indicated that he would like to remove all of the $130,000 in cash from his Company and has asked you to determine whether it would be better to take it out in the form of all non-eligible dividends or all salary. Assignment: The Maximum Subarray Problem is the task of finding the contiguous subarray, within an array of numbers, that has the largest sum. For example, for the sequence of values (2,1,3,4,1,2,1,5,4) the contiguous subsequence with the largest sum is (4,1,2,1), with sum 6 . For an arbitrary input array of length n, two algorithms that compute the sum of the maximum subarray were discussed in class: (a) a brute-force algorithm that solves the problem in O(n 2) steps, and (b) a divide-andconquer algorithm that achieves O(nlogn) running time. 1. (50 points) Implement in Java the algorithms attached below as Algorithms 1 , and 2 Your program must prompt the user to enter the size of the vector n, and output the time taken by each of the three algorithms. To measure the running time you can use the snippet of code attached below. Choose at random the numbers in the array (including the sign). 2. (20 points) Test the algorithms with different values of n and fill the following table with the running times measured (put the table in the code header). - You may run into problems, such as running out of memory or the program taking too much time. If that is the case, adjust the values of n accordingly, but make sure that you still have 5 columns of data. 3. ( 30 points) Based on the running times observed, draw conclusions about the running times obtained in the analysis. Do they match or not? Provide your answers in the remarks section of the code header. It is not enough to simply say: yes, they match. You have to justify your claim based on the running times measured (the table). Also, it is not enough to say Divide and conquer is faster. We know that, it is written above. You need to show how your measurements prove that Brute Force is O(n 2) and Divide and Conquer is O(nlogn) on these inputs. 4. (Extra credit) There exists a dynamic-programming algorithm due to Kadane that runs in linear time, which is optimal because you need at least to read each number in the input. For extra credit, implement this dynamic programming algorithm as well and test it along the other three. You can put all your measurements in the same table. Example code to measure time: // store the time now long startime = System. nanoTime(); // here goes the fragment of code // whose execution time you want to measure // display the time elapsed System. out.println("t= "+(System. nanoTime() - startTime)+" nanosecs."Previous questionNext question Compare between Bitmap and Object Images, based on: -What are they made up of? -What kind of software is used? -What are their requirements? -What happened when they are resized?
