Data is being sent from a source PC to a destination server. Which three statements correctly describe the function of TCP or UDP in this situation? (Choose three.) 1. The TCP source port number identifies the sending host on the network 2. UDP segments are encapsulated within IP packets for transport across the network. 3. The source port field identifies the running application or service that will 4. The TCP process running on the PC randomly selects the destination port when 5. TCP is the preferred protocol when a function requires lower network
6. The UDP destination port number identifies the application or service on the handle data returning to the PC establishing a session with the server. overhead server which will handle the data.

For this question, you need to implement a simple linear regression from scratch without using a library. The linear equation that you need to use for this exercise is y=50x+22, which you will use to generate some synthetic data with random variation to make the problem interesting.

Lets discuss more in detail.

To begin, you need to randomly select 20 x values between 0 and 100 using a uniform distribution. To do this, you can use a for loop to iterate through the range of 0 to 100 and randomly select 20 x values.

Once you have your x values, you can then use the linear equation of y=50x+22 to calculate the corresponding y values. Finally, you can use these x and y values to create a linear regression and check if it rounds to the original equation.

Grading criteria: The result of your linear regression should round to the original equation. It is not expected to be perfect.

You can find more detailed steps on how to solve this problem in the sample notebook that will be going over in class. This should get you 80% through problem 1.

The term "internet" is just the collection of networks that can be joined together. The correct option is E.

The internet is a vast network of networks. It's a global network of computers, and it's used by millions of people every day. There's no central organization that controls the internet. Instead, it's made up of a vast number of networks that are connected together. This makes it possible for people to communicate with each other no matter where they are in the world.The internet is used for many different purposes. It's a tool for communication, for research, for shopping, for entertainment, and for many other things. It's also an important tool for businesses, governments, and organizations of all kinds. The internet has changed the way we live and work in many ways, and it will continue to do so in the future.There are many different kinds of networks that make up the internet. These include local area networks (LANs), wide area networks (WANs), and metropolitan area networks (MANs). Each of these networks has its own set of protocols and technologies that are used to connect computers together.The internet is also made up of many different kinds of servers and other devices. These include web servers, file servers, routers, switches, and firewalls. Each of these devices has a specific function within the internet, and they all work together to make it possible for people to communicate and share information.Therefore, the correct answer is E.

If Iwina's media streaming device supports a transmission speed of up to 200 Mbps, I would recommend a wireless router that supports at least 802.11n wireless standard.

What is a 802.11n wireless standard?

802.11n is a wireless networking standard that operates on both the 2.4 GHz and 5 GHz frequency bands. It offers higher speeds and greater range compared to earlier wireless standards, and is commonly used in home and small business networks.

Thus, if Iwina's media streaming device supports a transmission speed of up to 200 Mbps, I would recommend a wireless router that supports at least 802.11n wireless standard. This wireless standard supports a theoretical maximum speed of up to 600 Mbps, which should provide enough bandwidth to support Iwina's device. Alternatively, a router that supports the newer 802.11ac wireless standard could also be considered, as it offers even higher theoretical speeds.

Here's a Python program that displays the Samzo Restaurant menu and prompts the user to make a selection:

The Program

print("********Welcome to Samzo Restaurant Menu**********")

print("(1) Milk R10.99")

print("(2) Coke R21.00")

print("(3) Chips R22.75")

print("(4) Bread R11.50")

print("(5) Pap & Steak R43.00")

while True:

   selection = int(input("Please enter a number (1-5) to select an item, or 0 to quit: "))

   if selection == 0:

       print("Thank you for visiting Samzo Restaurant!")

       break

   elif selection == 1:

       print("You have selected Milk for R10.99")

   elif selection == 2:

       print("You have selected Coke for R21.00")

   elif selection == 3:

       print("You have selected Chips for R22.75")

   elif selection == 4:

       print("You have selected Bread for R11.50")

   elif selection == 5:

       print("You have selected Pap & Steak for R43.00")

   else:

       print("Invalid selection. Please try again.")

This program uses a while loop to repeatedly prompt the user for a selection until they enter 0 to quit. It uses an if statement to determine which menu item was selected based on the number entered by the user, and then displays the name and price of the selected item.

If the user enters an invalid selection (i.e. a number outside of the range 0-5), the program displays an error message and prompts the user to try again.

Often, programmers list the constructor first because it is the first method used when an object is created.

A constructor is a unique method of the class that is executed when an instance of a class is created. It has the same name as the class and is created as a separate method. The constructor is also used to assign values to variables when the object is created. You can define constructors with or without parameters. The object's properties and variables can be initialized with the help of a constructor. Here's an example of how to create a constructor:

class Car {

String name;

int model_number;

Car(String name, int model_number) {

// The constructorthis.name = name;

this.model_number = model_number;

}

public static void main(String[] args) {

  Car car1 = new Car("BMW", 11);

  Car car2 = new Car("Audi", 2021);

   System.out.println(car1.name + " " + car1.model_number);

   System.out.println(car2.name + " " + car2.model_number);

   }

}

As we have defined a constructor for the Car class and used the Car object to initialize the name and model_number properties.
