Explanation:
Here is TestAutomobiles.java
public class TestAutomobiles { //class name
public static void main(String args[]) { //start of main method
Automobile auto = new Automobile(123, "ABC", "XYZ", 2010, "MMM", 30, 150, "White"); //creates an object of Automobile class and calls its constructor passing the values for each of the fields
System.out.println("Initial Speed: " + auto.getSpeed()); //calls getSpeed method to get the current speed using object auto. The current speed is 150
System.out.println("Speed after applying acceleration: " + auto.Accelerate()); //calls Accelerate() method to increase the current speed to 5
System.out.println("Speed after applying brake: " + auto.Brake()); //calls Brake() method to decrease the current speed to 5
System.out.println("Speed after applying acceleration: " + auto.Accelerate(180)); //calls overloading Accelerate() method to increase the current speed to 180
System.out.println("Speed after applying brake: " + auto.Brake(50)); } } //calls overloading Brake() method to decrease the current speed to 50

Answer:
User Datagram Protocol (UDP) , transport-layer segment.
Explanation:
The User Datagram Protocol is popularly known as UDP. It is defined as the communication protocol which is used across the internet for any time sensitive transmission like the DNS lookup or the video playback.
The UDP provides a unreliable and connectionless service to a invoking application.
The transport layers on sending side converts the application messages which it
from the
into a transport layer segment called as the transport layer segments. This is achieved by breaking down the application messages into a smaller chunks and then adding the transport layer header into each chunk so as to create a transport layer segment.
