Explain Session Management in your OWN words.

in Java, I am writing a program where you need to pick a color. The color must be red, blue, or green and is a user input. If they put in a different value I need the program to stop running. So I essentially need to write code that says, if variableColor does not equal "red", "blue", or "green" then I need to print the statement "invalid response" and exit the program. How can I write this?

Compare and contrast the WiFi IEEE 802.11ax standard and latest Bluetooth standards. Your comparison should be based on technical specification and performance (e.g., data rate, modulation, range, no of channels and MIMO antenna, security features and other parameters; you should list as many as you can). Do you view WiFi and Bluetooth as competing or complimentary technologies? Justify your answer

JAVA:

You're given two classes List.java and Node.java. In your List class you're supposed to implement the methods toFront, print, and toBack. The Node class is used as a reference no edit necessary.

LIST:

public class List {

protected Node head, tail;

/**

* Initialize the list to empty. Both head and tail

* are null references in this case.

*/

public List() {

// TODO Auto-generated constructor stub

head = tail = null;

}

/**

* Add nodeToAdd to the front (head) of this list.

* @param nodeToAdd to the front of this list.

*/

public void toFront(Node nodeToAdd) {

}

/**

* Print all nodes from the list to System.out

*/

public void print( ) {

}

/**

* Add nodeToAdd to the back (tail) of this list.

* @param nodeToAdd node to add at the back (tail) of this list.

*/

public void toBack (Node nodeToAdd) {

}

}

NODE:

public class Node {

protected String contents; // the contents of this LLNode

protected Node next; // Reference to next LLNode in list.

/**

* The constructor -- The default constructor will

* build a node with a null reference for the string

* and a null reference for the next item in the list.

*/

public Node() {

this(null, null);

}

/**

* Initializes this linked list node to the string

* given and sets the next reference to null.

* @param contents The string to store in this LLNode

*/

public Node(String contents) {

this (contents, null);

}

/**

* Initializes this linked list node to the string and

* LLNode reference passed in.

* @param contents The string to store in this LLNode

* @param next The reference to the next item in the List.

*/

public Node(String contents, Node next) {

this.contents = contents;

this.next = next;

}

/**

* @return the contents of this linked list node.

*/

protected String getContents() {

return contents;

}

/**

* @param contents the string to store in this linked list node.

*/

protected void setContents(String contents) {

this.contents = contents;

}

/**

* @return the reference to the next item in the Linked List

*/

protected Node getNext() {

return next;

}

/**

* @param next the Node to set as the node to follow this item in the list.

*/

protected void setNext(Node next) {

this.next = next;

}

}

Write an algorithm that doubles ALL the prime values of a linked lists, and then output the whole new list.

Code in c++, do not use loops, make it as simple as it can be. Thanks!

Background Well it has finally happened; AMC’s “The Walking Dead” has become a reality. The zombie apocalypse took place. It has been a couple of years since we have started to “rebuild” our society, and now is the time for you to be able to shine. We have come across technology that will allow for us to get back to life as it once was in the early 2000’s. Yes, we are still going to be 17 years back but it’s better than nothing. With all the Computer Scientists and Engineers that survived in the area, everything is almost back to normal except for the use of cell phones. People have been able to start-up businesses again, and we are trying to become as we once were. People work and get paid and of course we want the commodities that we once had. In a venture of remembering how people were glued to their cell phones you have decided to start a service. Why not!? You found a warehouse that had all the cell phones that you can distribute to those around in the area, and you have been working with others to get an infrastructure back. You now just have to come up with a quick system to be able to get people hooked before they get used to not having their phones anymore. With the fact that you must have a quick turn-around, you are putting together a simple plan and will later expand on the idea. You have everything ready to go and to sign people up, but you still need the billing to be generated. This is what you must work on now. You are only going to give users the options of two types of service, regular and premium.

To compute the rates you have the following established: 1. Regular service - $6.00 plus first 50 minutes free. Charges for over 50 minutes are $0.20 per minute. 2. Premium service - $15.00 plus: a. For calls made from 6:00am to 6:00pm, the first 75 minutes are free; charges for over 75 minutes are $0.10 per minute. b. For calls made from 6:00pm to 6:00am, the first 100 minutes are free; charges for over 100 minutes are $0.05 per minutes. Task Your task at the moment is to calculate and print out the bill for your customers. Your program should: 1. prompt the user to enter an account number, 2. a service code (type char), a. A service code of r or R means regular service b. A service code of p or P means premium service c. Treat any other character as an error 3. the number of minutes the service was used. Your program should output the account number, type of service, number of minutes the telephone service was used, and the amount due from the user. For the premium service, the customer may be using the service during the day and the night. Therefore, to calculate the bill, you must ask the user to input the number of minutes the service was used during the day and the number of minutes the service was used during the night. Concepts to follow: 1. Assign values to all constant variables that are associated with charges and number of minutes provided in the problem description. 2. The only information the user enters are: account number, type of service, minutes used, and day/night time minutes used based on the plan they have. 3. Remember you are dealing with money therefore should only have 2 decimal places. 4. You must use both a switch statement AND if/else, if/else if’s, or if’s as you see fit. 5. Keep in mind to check for input validation. If validation is incorrect you should have an error message and “kill” your program. 6. Do not use loops

Ch 4 Program 4A: Factorial.java                                                 

Please adhere to the Standards for Programming Assignments and the Java Coding Guidelines.

Write a program that computes the factorial of a number that is input from the user.  

A factorial is the product of all the numbers up to the number entered.  

For example, 6-factorial is 720 because 6*5*4*3*2*1 is 720.  

Six-factorial is written as 6!  

Prompt the user for the numeric input between 1 and 10.  

Do not accept numbers greater than 10 or less than 1.( Check out the input/data Validation page on Canvas in module 4B)

Calculate and display the factorial. All code must reside in the main() method

Do not use any concept that is not covered in class.  

Include output from this Test Data:          22

Later you will be making a logo for your project website. For now, you are going to style a photograph for your project.

Choose at an appropriate picture from one of these sources:

• A photograph you took
• A photograph that is fine for modification under a Creative Commons license. Try the search engine HERE (Links to an external site.) with the "modify" box checked.
• Another resource that is not copyrighted.

Save your original photograph with the names of original.psd and original. jpg before you modify it.

Then use "save as" to create another copy of your photograph and modify it using at least TWO techniques covered so far. You may do more if you wish.

Integrate your final photograph into your Dreamweaver website.

Turn in the following:

1. Both the original and modified photographs in a zipped file that you upload here, four files total. (60 points)

2. In your submission comments, provide the URL of your webpage where you have put the file on MyDrive. Your graphic should be in a separate folder for graphics, and your image and web page should render properly. If your graphic doesn't appear, check the reference. (30 points)

3. AND, also in the submission comments, describe the modifications you made to your photograph. (10 points)

Andrea Stevens Cosmetics is a small cosmetics company that has a network of 30 computers. They are currently using a 100BaseT network that is wired with Category 6 Plenum cable. Their computers were purchased six years ago as a single buy from Dell. The computers have single Intel i3 processors, 2 GB RAM, and 500 GB hard drives. Their network has two 24 port hubs and a gateway router that connects them to a Cox cable modem. Most of their computers are used for order processing and inventory control. The computers are arranged in a workgroup called ASC, with all hard drives and printers shared. The manufacturing plant has computerized equipment that is on a separate network that is self-contained and isolated. You are hired as a consultant to bring their network into the 21st century. Based on your knowledge, experience, and what you have read in this week's assignment, propose an upgrade to this architecture. Describe the components you would recommend and how the network would be configured. Your goal should be a network that will support them for the next five years. Because the information in this mini-case is limited, you will have to make some assumptions. Be sure to document any assumptions that you make.

Write a C program that reads three integers and then prints them in the order read and reversed. Use four functions: main, one to read the data, one to print them in the order read, and one to print them reversed.
