Which of the following are easy/difficult to handle in Virtual-Circuit and Datagram subnets, and why?
i) Router memory space
ii)Quality-of-service
iii) Congestion control
iv) Address parsing time
Quality-of-service and Congestion control are easy to handle in Virtual-Circuit.
Router memory space and Address parsing time are easy to handle in Datagram subnets.
Why is Router memory space difficult to handle in Virtual-Circuit?i) Router memory space:
In virtual-circuit subnets, routers need to maintain the connection state information for the duration of the virtual circuit. This information can take up a significant amount of memory space, which may become a problem if a large number of virtual circuits are present.
On the other hand, in datagram subnets, routers do not need to maintain connection state information, so memory space is not as much of an issue.
ii) Quality-of-service:
Virtual-circuit subnets are generally better suited for providing quality-of-service guarantees, such as guaranteed bandwidth, low latency, and minimal packet loss. This is because virtual circuits are established beforehand, and the network can reserve resources for the duration of the connection. Datagram subnets, on the other hand, do not provide such guarantees, as packets are forwarded on a best-effort basis.
iii) Congestion control:
Virtual-circuit subnets typically have better congestion control mechanisms, as they can react quickly to changing network conditions by adjusting the routing tables and resource allocations. Datagram subnets may have a more difficult time with congestion control, as they rely on packet-level mechanisms, such as packet dropping, to regulate network traffic.
iv) Address parsing time:
In general, address parsing time is not significantly affected by the choice of subnet type, as address parsing is typically done at the packet level, rather than at the virtual-circuit level.
However, it is worth noting that virtual-circuit subnets may have slightly higher parsing overhead, as they need to maintain connection state information for each virtual circuit.

b. calculates the average daily sales for the week
c. displays the total and average sales for the week.
Each of the three components of the program should be handled by a different method.
Here is a Java application that asks the user for the daily sales for each day of a week using a repetition loop and calculates its total, calculates the average daily sales for the week, and displays the total and average sales for the week.
The Programimport java.util.Scanner;
public class WeeklySales {
public static void main(String[] args) {
double[] sales = getDailySales();
double totalSales = calculateTotalSales(sales);
double averageSales = calculateAverageSales(sales);
displaySales(totalSales, averageSales);
}

}
}
The getDailySales() method asks the user for the daily sales for each day of the week using a for loop and stores them in an array of doubles. It returns the array.
The calculateTotalSales(double[] sales) method calculates the total sales for the week by adding up all the daily sales in the array. It returns the total sales as a double.
The calculateAverageSales(double[] sales) method calculates the average daily sales for the week by dividing the total sales by the number of days (i.e., the length of the array). It returns the average sales as a double.
The displaySales(double totalSales, double averageSales) method displays the total and average sales for the week to the user using the println() method.

State of Indiana v. IBM is an example of a lengthy and expensive lawsuit that arose out of a failed software development project. In 2004, Indiana’s new governor, Mitch Daniels, announced that his state’s welfare system was “broken” and “plagued by high error rates, fraud, wasted dollars and poor conditions for its employees, and very poor service to its clients.”
In 2006, the state of Indiana and IBM entered into a 10-year and $1.3 billion Master Services Agreement (MSA) to update the state’s welfare system. The SDA required the establishment of call centers and remote electronic access for welfare applications. A paperless documentation system would reduce fraud. Indiana would benefit from the cost-savings in hiring fewer caseworkers if welfare applicants could apply online.
The IBM/Indiana MSA was extremely complex, containing more than 160 pages and extensive attachments, which included ten exhibits, twenty-four schedules and ten appendices. The parties agreed to a ten-year MSA, but Indiana terminated the agreement less than three years into the SDA, declaring that IBM was in breach. In its twelve-county pilot implementation, Indiana documented several problems early on, such as call center miscues, the delayed processing of applications and multiple problems with processing applications for the redetermination of welfare benefits.
Both parties filed suit against each other for breach of contract. Indiana charged that IBM’s product was slow, incorrectly imaged key documents, missed scheduling benchmarks and failed to satisfy Indiana’s policy objectives. IBM defended against these claims, charging that Indiana had created delays by continually changing specifications. IBM also invoked a commercial impracticability defense based upon the large number of new claims for welfare that flooded the system in the wake of the 2008 economic meltdown.
The Indiana Supreme Court found that IBM had materially breached its contract with the state. IBM, however, had negotiated millions of dollars in early termination fees that the state had to pay. The Indiana Supreme Court upheld the lower courts’ awarding of $40 million in assignment fees and $9,510,795 in equipment fees to IBM. The trial court’s award of $2,570,621 in early termination damage payments and $10,632,333 in prejudgment interest to IBM was reversed and the case was remanded to determine both parties’ damages.
This case illustrates the need for careful negotiation by attorneys to protect their clients if the contract is terminated and to clearly specify rights and remedies in the event of breach. Computer companies must be realistic as to what projects they can successfully complete and deliver, while also protecting themselves in the negotiation stage against foreseeable hazards, such as unclear benchmark specifications and excessive change order.

Do some research about contracts.
How could this project have been managed better? What improvements would you suggest in these types of contract?
What items will you pay special attention to when dealing with contracts?
Please add references
The Indiana v. IBM case highlights the importance of careful management of software development contracts to avoid costly legal disputes.
What is the software development about?To better manage these types of contracts, there are several improvements that can be made:
Clearly define the scope and objectives of the project: In this case, the parties agreed on a complex 160-page contract with extensive attachments that contained numerous exhibits, schedules, and appendices. However, the contract did not clearly define the scope and objectives of the project, which led to disagreements about what was expected from both parties.
Set realistic deadlines and benchmarks: The project timelines and benchmarks must be set realistically based on the complexity of the project. In this case, Indiana accused IBM of missing scheduling benchmarks and having slow delivery, while IBM accused Indiana of creating delays by continually changing specifications.
Establish clear communication channels: It is important to establish clear communication channels to facilitate collaboration between parties. In this case, there were several problems with call center miscues and the delayed processing of applications, indicating a breakdown in communication channels between Indiana and IBM.
Anticipate potential issues and include dispute resolution mechanisms in the contract: Parties must anticipate potential issues and include dispute resolution mechanisms in the contract to resolve issues efficiently. In this case, both parties filed lawsuits against each other, resulting in lengthy legal proceedings and costly damages.
When dealing with contracts, it is essential to pay special attention to several items, such as:

RC4 is a symmetric key stream cipher that is widely used for secure communication over the internet. It operates on bytes of data and generates a stream of pseudo-random bytes that are XORed with the plaintext to produce the ciphertext.
What is the program about?The RC4 algorithm consists of two parts: key setup and encryption/decryption.
Key setup:
Initialize the S-box with a permutation of the values 0 to 255, based on the key.Use the S-box to generate a pseudo-random stream of bytes called the keystream.Encryption/decryption:
XOR each byte of the plaintext with the corresponding byte of the keystream to produce the ciphertext.To decrypt the ciphertext, repeat the XOR operation using the same keystream.To implement RC4 in C++, you would need to write code to perform the following steps:
Read the key and plaintext/ciphertext from a file or user input.Perform key setup to generate the keystream.XOR the plaintext/ciphertext with the keystream to produce the ciphertext/plaintext.Write the ciphertext/plaintext to a file or output it to the console.Therefore, below are some general guidelines on how to implement RC4 in C++:
Declare arrays to store the key, plaintext/ciphertext, S-box, and keystream.Read the key and plaintext/ciphertext from a file or user input and store them in the appropriate arrays.Initialize the S-box with a permutation of the values 0 to 255 based on the key.Use the S-box to generate the keystream by iterating over the plaintext/ciphertext and XORing each byte with a pseudo-random value from the S-box.Write the ciphertext/plaintext to a file or output it to the console.Read more about program here:

Create a program using classes that does the following in the zyLabs developer below. For this lab, you will be working with two different class files. To switch files, look for where it says "Current File" at the top of the developer window. Click the current file name, then select the file you need.
(1) Create two files to submit:
ItemToPurchase.java - Class definition
ShoppingCartPrinter.java - Contains main() method
Build the ItemToPurchase class with the following specifications:
Private fields
String itemName - Initialized in default constructor to "none"
int itemPrice - Initialized in default constructor to 0
int itemQuantity - Initialized in default constructor to 0
Default constructor
Public member methods (mutators & accessors)
setName() & getName() (2 pts)
setPrice() & getPrice() (2 pts)
setQuantity() & getQuantity() (2 pts)
(2) In main(), prompt the user for two items and create two objects of the ItemToPurchase class. Before prompting for the second item, call scnr.nextLine(); to allow the user to input a new string. (2 pts)
(3) Add the costs of the two items together and output the total cost. (2 pts)
Here's the code:
The CodeItemToPurchase.java:
public class ItemToPurchase {
private String itemName;
private int itemPrice;
private int itemQuantity;
public ItemToPurchase() {
itemName = "none";
itemPrice = 0;
itemQuantity = 0;
}
public void setName(String name) {
itemName = name;
}
public String getName() {
return itemName;
}
public void setPrice(int price) {
itemPrice = price;
}
public int getPrice() {
return itemPrice;
}
public void setQuantity(int quantity) {
itemQuantity = quantity;
}
public int getQuantity() {
return itemQuantity;
}
}
ShoppingCartPrinter.java:import java.util.Scanner;
public class ShoppingCartPrinter {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
ItemToPurchase item1 = new ItemToPurchase();
System.out.println("Item 1");
System.out.println("Enter the item name:");
item1.setName(scnr.nextLine());
System.out.println("Enter the item price:");
item1.setPrice(scnr.nextInt());
System.out.println("Enter the item quantity:");
item1.setQuantity(scnr.nextInt());
scnr.nextLine();
ItemToPurchase item2 = new ItemToPurchase();
System.out.println("\nItem 2");
System.out.println("Enter the item name:");
item2.setName(scnr.nextLine());
System.out.println("Enter the item price:");
item2.setPrice(scnr.nextInt());
System.out.println("Enter the item quantity:");
item2.setQuantity(scnr.nextInt());
int totalCost = item1.getPrice() * item1.getQuantity() + item2.getPrice() * item2.getQuantity();
System.out.println("\nTotal cost: $" + totalCost);
}
}
This implementation creates two objects of the ItemToPurchase class, prompts the user for their names, prices, and quantities, calculates the total cost, and prints it out.

672.2The internet 24A buffer is 2MiB in size. The lower limit of the buffer is set at 200KiB and the higher limit is set at 1.8MiB.Data is being streamed at 1.5Mbps and the media player is taking data at the rate 600kbps.You may assume a megabit is 1048576bits and a kilobit is 1024bits.a)Explain why the buffer is needed.[2]b)i)Calculate the amount of data stored in the buffer after 2 seconds of streaming and playback.You may assume that the buffer already contains 200KiB of data.[4]ii)By using different time values (such as 4 secs, 6 secs, 8 secs, and so on) determine how long it will take before the buffer reaches its higher limit (1.8MiB).[5]c)Describe how the problem calculated in part b) ii) can be overcome so that a 30-minute video can be watched without frequent pausing of playback
a) The buffer is needed to ensure smooth playback of streamed media by storing a certain amount of data in advance. This is done to prevent interruptions due to network congestion or variations in the streaming rate.
How to calculate the datab) i) The amount of data streamed in 2 seconds is (1.5Mbps * 2s) = 3MB. The amount of data played back in 2 seconds is (600kbps * 2s) = 150KB. Therefore, the amount of data stored in the buffer after 2 seconds is (3MB - 150KB - 200KiB) = 2.6MB.
ii) To determine how long it will take before the buffer reaches its higher limit of 1.8MiB, we can use the following formula:
Time to reach limit = (higher limit - lower limit - current buffer size) / streaming rate
= (1.8MiB - 200KiB - 2MiB) / 1.5Mbps
= 8 seconds
Therefore, it will take 8 seconds for the buffer to reach its higher limit.
c) To overcome the problem of frequent pausing of playback, a larger buffer can be used. This will allow more data to be stored in advance, reducing the impact of network congestion or variations in the streaming rate.'
Additionally, adaptive bitrate streaming can be used, where the streaming rate is dynamically adjusted based on the available network bandwidth, to ensure a more consistent streaming experience. Finally, a content delivery network (CDN) can be used to deliver the media from servers located closer to the viewer, reducing the impact of network latency and improving overall streaming performance.

Construction a wall in to divide an office is it a project or no project
Answer:
Constructing a wall to divide an office can be considered a project.
A project is a temporary endeavor with a specific goal or objective, and constructing a wall to divide an office fits this definition. It has a specific goal (dividing the office) and is temporary in nature (once the wall is constructed, the project is complete).
Additionally, constructing a wall to divide an office may require planning, resources, and coordination with stakeholders such as the building owner, architects, engineers, contractors, and employees who will be impacted by the construction. This would further support the argument that it is indeed a project.

Answer:
// MichiganCities.cpp - This program prints a message for invalid cities in Michigan.
// Input: Interactive
// Output: Error message or nothing
#include <iostream>
#include <string>
using namespace std;
int main()
{
// Declare variables
string inCity; // name of city to look up in array
const int NUM_CITIES = 10;
// Initialized array of cities
string citiesInMichigan[] = {"Acme", "Albion", "Detroit", "Watervliet", "Coloma", "Saginaw", "Richland", "Glenn", "Midland", "Brooklyn"};
bool foundIt = false; // Flag variable
int x; // Loop control variable

cin >> inCity;
// Write your loop here
for (x = 0; x < NUM_CITIES; x++) {

// a match. Set the flag to true if city is found.
if (citiesInMichigan[x] == inCity) {
foundIt = true;
break;
}
}
if (!foundIt)
cout << "Not a city in Michigan." << endl;
else
cout << "Valid city in Michigan." << endl;
return 0;
} // End of main()
Explanation:
In this version of the code, we added a loop that goes through the citiesInMichigan array and compares each element with the input city using an if statement. If a match is found, the foundIt flag is set to true and the loop is exited using break. Finally, we added an else block to the conditional statement that prints "Valid city in Michigan." if the city is found.
Read in a 3-character string from input into variable passCode. Declare a boolean variable containsAlpha and set containsAlpha to true if passCode contains an alphabetic character. Otherwise, set containsAlpha to false.
Ex: If the input is 4cx, then the output is:
Valid passcode
in c++
Here's the C++ code to accomplish the task:
#include <iostream>
#include <cstring>
#include <cctype>
using namespace std;
int main() {
char passCode[4];
bool containsAlpha = false;
cout << "Enter a 3-character passcode: ";
cin >> passCode;
for (int i = 0; i < strlen(passCode); i++) {
if (isalpha(passCode[i])) {
containsAlpha = true;
break;
}
}
if (containsAlpha) {
cout << "Valid passcode\n";
} else {
cout << "Invalid passcode\n";
}
return 0;
}
How to explain the programIn this code, we first declare the passCode variable as a character array of size 4 to accommodate the 3-character passcode plus the null terminator. We also declare the containsAlpha boolean variable and initialize it to false.
We then prompt the user to enter a 3-character passcode and read it into the passCode variable using the cin function.
Next, we loop through the characters in passCode using a for loop and use the isalpha function from the cctype library to check if the current character is alphabetic. If it is, we set containsAlpha to true and break out of the loop.
Finally, we use an if-else statement to check the value of containsAlpha and output either "Valid passcode" or "Invalid passcode" accordingly.
