Chapter 16, Problem 3RQ
Explanation of Solution
Data quality:
Data quality is one of the key features of enterprise data management. The data quality can be measured based on the following:
- Uniqueness
- Accuracy
- Consistency
- Timeliness
Having high-quality data is an important in an organization. The following are the reasons of importance of data quality:
Importance of data quality:
Minimize the project risk occurred in the information technology:
- Low quality data such as reusing the data from other available systems leads to extra works and delay.
- Thus, the high quality data minimize the risks in the projects...

RSA and Diffie-Hellman are important algorithms in public-key cryptography. What are the differences between the two? Assume you intercept the ciphertext C = 105 sent to a user whose public key is e = 7, n = 403. Explain in detail how you will find the private key of the user and crack the ciphertext. What is the plaintext M?
CBC-Pad is a block cipher mode of operation commonly used in block ciphers. CBC-Pad handles plain text of any length. Padding is used to ensure that the plaintext input is a multiple of the block length. Hence, the ciphertext is longer than the plaintext by at most the size of a single block.Assume that the original plaintext is 556 bytes and the size of a cipher block is 28 bytes. What will be the padding? If the original plaintext is an integer multiple of the block size, will padding still be needed? Why or why not?

- Inheritance & Polymorphism (Ch11) There are 6 classes including Person, Student, Employee, Faculty, and Staff. 4. Problem Description: • • Design a class named Person and its two subclasses named student and Employee. • Make Faculty and Staff subclasses of Employee. • A person has a name, address, phone number, and e-mail address. • • • A person has a class status (freshman, sophomore, junior and senior). Define the status as a constant. An employee has an office, salary, and date hired. A faculty member has office hours and a rank. A staff member has a title.

The warranty states that if the device fails during its first year of use, you get a new device for no cost, and this new device carries exactly the same warranty. However, if it fails after the first year of use, the warranty is of no value. You plan to use this device for the next six years. Therefore, any time the device fails outside its warranty period, you will pay $300 for another device of the same kind. (We assume the price does not increase during the six-year period.) The time until failure for a device is gamma distributed with parameters α = 2 and β = 0.5. (This implies a mean of one year.) Use @RISK to simulate the six-year period. Include as outputs (1) your total cost, (2) the number of failures during the warranty period, and (3) the number of devices you own during the six-year period.

- Please answer the JAVA OOP Programming Assignment scenario below: Patriot Ships is a new cruise line company which has a fleet of 10 cruise ships, each with a capacity of 300 passengers. To manage its operations efficiently, the company is looking for a program that can help track its fleet, manage bookings, and calculate revenue for each cruise. Each cruise is tracked by a Cruise Identifier (must be 5 characters long), cruise route (e.g. Miami to Nassau), and ticket price. The program should also track how many tickets have been sold for each cruise. Create an object-oriented solution with a menu that allows a user to select one of the following options: 1. Create Cruise – This option allows a user to create a new cruise by entering all necessary details (Cruise ID, route, ticket price). If the maximum number of cruises has already been created, display an error message. 2. Search Cruise – This option allows to search a cruise by the user provided cruise ID. 3. Remove Cruise – This op…arrow_forwardI need to know about the use and configuration of files and folders, and their attributes in Windows Server 2019.arrow_forwardSouthern Airline has 15 daily flights from Miami to New York. Each flight requires two pilots. Flights that do not have two pilots are canceled (passengers are transferred to other airlines). The average profit per flight is $6000. Because pilots get sick from time to time, the airline is considering a policy of keeping four *reserve pilots on standby to replace sick pilots. Such pilots would introduce an additional cost of $1800 per reserve pilot (whether they fly or not). The pilots on each flight are distinct and the likelihood of any pilot getting sick is independent of the likelihood of any other pilot getting sick. Southern believes that the probability of any given pilot getting sick is 0.15. A) Run a simulation of this situation with at least 1000 iterations and report the following for the present policy (no reserve pilots) and the proposed policy (four reserve pilots): The average daily utilization of the aircraft (percentage of total flights that fly) The…arrow_forward
