For a given CPU, the cycle latency for a set of operations are given as follows:

Addition: 4

Subtraction: 8

Multiplication: 64

Division: 80

If the clock of this CPU runs at 3GHz, find the following

How many operations of each of the list above can this CPU perform in 5 minutes?

If we have a set of operations that contains 10^9 of each operation in the list in part 1, compute the required time in seconds to execute the set. Please explain the formula used.

Please make your Task class serializable with a parameterized and copy constructor, then create a TaskListDemo with a main( ) method that creates 3 tasks and writes them to a binary file named "TaskList.dat". We will then add Java code that reads a binary file (of Task objects) into our program and displays each object to the console. More details to be provided in class.

Here is a sample transaction with the user (first time the code is run):

Previously saved Tasks from binary file:
[None, please enter new Tasks]

Please enter task name (or "quit" to exit): Ace CS 112 Final Exam
Please enter due date (in form MM/DD/YYYY): 10/10/2019
Please enter deadline : 3:20 PM
Please enter priority : 1

After 1 Task has been saved (second time the code is run):

Previously saved Tasks from binary file:
Task [name=Ace CS 112 Midterm Exam, dueDate=10/10/2019, deadline=3:20 PM, priority=High]

Please enter task name (or "quit" to exit): quit

I don't know how to print the priorities High, medium, and Low in the toString method to where it is stored in the binary file after the user types 1, 2, or 3. 1 for high, 2 for medium, and 3 for low.

You will create a program that will follow the queuing theory of the Barbershop Problem. You will initially create a flow chart for the assignment to be uploaded to the Queuing Theory Flowchart assignment drop box. In this you will use queues and random number generators to complete this project. You will create three queues

1. Couch - the area where patron will wait just prior to getting their hair cut;
2. Line - the area where patron will form a line just before reaching the couch; and
3. Cashier - the area where patrons will line up to pay just before exiting the barbershop and after finishing their haircut.  

You will create a container for the barbers chairs (list) . The wait times for the barbers will be random. Barber one will be the fastest and barber three will be the slowest. Randomize the wait times accordingly.  

The cashier wait times will also vary randomly.

Barber wait times.

• 1 second (system time) = 5 minutes
• Max time 2 hours
• Min time 20 minutes.

Cashier wait time

• 1 second (system time) = 1 minute
• Max time 3 minutes
• Min time 1 minute.

Give the definition of a static method called showArray that has an array of base type char as a single parameter and that writes to the screen each character in the array on a separate line. It then writes the same array characters in reverse order. This method returns a character array that holds these two lines of characters in the order that you printed them.

3) Please answer full question thoroughly (A- J) showing detailed work. Double check answer and work to ensure it is correct for thumbs up.

The data warehouse is one of the most important business intelligence tools a business needs to have. It turns the massive amount of data generated from multiple sources into a format that is easy to understand.

JAVA CODE

Using the PurchaseDemo program and output from the previous problem as your guide, write a program that uses the Purchase class to set the following prices, and buy the number of items as indicated. Calculate the subtotals and total bill called total. Using the writeOutput() method display the subtotals as they are generated as in the PurchaseDemo program. Then print the total bill at the end. You may use integer, double, and String variables as needed but you may use only one object of the Purchase class and a for loop.

(Use the readInput() method for the following input data, you may assume the prompts and Scanner for the readInput() method takes place but you need not include either in your program output. )

Oranges: 10 for 2.99 buy 2 dozen oranges

Eggs; 12 for 1.69 buy 3 dozen eggs

Apples: 3 for 1.00 buy 20 apples

Watermelons: 4.39 each buy 2 watermelons

Organizations need to know the value of their data to find the best way to protect it. The data must be categorized according to the organization’s level of concern for confidentiality, integrity, and availability. The potential impact on assets and operations should be known in case data, systems, and/or networks are compromised (through unauthorized access, use, disclosure, disruption, modification, or destruction).

Choose an organization from the Health Care, Finance, or Education sector to study throughout this course.

Based on your chosen organization, ensure you:

• Discuss the organization’s data.
• Discuss the organization’s categorization of the data based on the Standards for Security Categorization of Federal Information and Information Systems.
