Program Plan Intro
Memory
- The computer memory is used for storing program instructions and data.
- The two main commonly used types of memories are Random Access Memory (RAM) and Read Only Memory (ROM).
- RAM stores data and the general purpose programs that are executed by the machine.
- It is temporary and the contents can be changed at any time and the contents can be erased when the power is turned off.
- ROM on the other hand is permanent and is used for storing initial boot up instructions of the machine.
Processing unit
- The Central Processing Unit (CPU) is considered as the heart of the computing system.
- It includes three main components that is the Control Unit (CU), one or more Arithmetic Logic Units (ALUs) and various registers.
- A CPU that is implemented on a single chip is known as microprocessor.
- Hence a processing unit is mainly used for computation and processing of information.

If a UDP datagram is sent from host A, port P to host B, port Q, but at host B there is no process listening to port Q, then B is to send back an ICMP Port Unreachable message to A. Like all ICMP messages, this is addressed to A as a whole, not to port P on A.
(a) Give an example of when an application might want to receive such ICMP messages.
(b) Find out what an application has to do, on the operating system of your choice, to receive such messages.
(c) Why might it not be a good idea to send such messages directly back to the originating port P on A?

This week we will be building a regression model conceptually for our discussion assignment. Consider your current workplace (or previous/future workplace if not currently working) and answer the following set of questions. Expand where needed to help others understand your thinking:
What is the most important factor (variable) that needs to be predicted accurately at work? Why? Justify its selection as your dependent variable.

Create a Book record that implements the Comparable interface, comparing the Book objects by year - title: String > - author: String - year: int Book + compareTo(other Book: Book): int + toString(): String Submit your source code on Canvas (Copy your code to text box or upload.java file) > Comparable 2. Create a main method in Book record. 1) In the main method, create an array of 2 objects of Book with your choice of title, author, and year. 2) Sort the array by year 3) Print the object.

Our problem is a 2x2 binary sudoku, which in our case has two simple rules: •No column may contain the same value twice •No row may contain the same value twice If we assign each square in our sudoku to a variable like so: 1 V V₁ V3 V2 we want our circuit to output a solution to this sudoku. Note that, while this approach of using Grover's algorithm to solve this problem is not practical (you can probably find the solution in your head!), the purpose of this example is to demonstrate the conversion of classical decision problems into oracles for Grover's algorithm. Turning the Problem into a Circuit We want to create an oracle that will help us solve this problem, and we will start by creating a circuit that identifies a correct solution, we simply need to create a classical function on a quantum circuit that…arrow_forward

Create a CashRegister class that can be used with the RetailItem class. The CashRegister class should be able to internally keep a list of RetailItem objects. The class should have the following methods: A method named purchase_item that accepts a RetailItem object as an argument. Each time the purchase_item method is called, the RetailItem object that is passed as an argument should be added to the list. A method named get_total that returns the total price of all the RetailItem objects stored in the CashRegister object’s internal list. A method named show_items that displays data about the RetailItem objects stored in the CashRegister object’s internal list. A method named clear that should clear the CashRegister object’s internal list. Demonstrate the CashRegister class in a program that allows the user to select several items for purchase. When the user is ready to check out, the…arrow_forward5. RetailItem ClassWrite a class named RetailItem that holds data about an item in a retail store.

You are tasked with creating a Java record of Dog (UML is shown below). The dog record should include the dog's name, breed, age, and weight. You are required to implement the Comparable interface for the Dog record so that you can sort the records based on the dogs' ages. Create a Java record named Dog.java. name: String breed: String age: int weight: double + toString(): String > Dog + compareTo(otherDog: Dog): int > Comparable 2. In the Dog record, establish a main method and proceed to generate an array named dogList containing three Dog objects, each with the following attributes: Dog1: name: "Buddy", breed: "Labrador Retriever", age: 5, weight: 25.5 Dog2: name: "Max", breed: "Golden Retriever", age: 3, weight: 30 Dog3: name: "Charlie", breed: "German Shepherd", age: 2, weight: 22 3.
