Recall that the name of a transport-layer packet is segment and that the name of a link-layer packet is frame. What is the name

AlladinOne [14]

Answer:

A network-layer packet is a data gram. A router forwards a packet based on the packet's IP (layer 3) address. A link-layer switch forwards a packet based on the packet's MAC (layer 2) address.

Explanation:

When the end system receives the unstructured bit stream from the physical wire, each layer removes the header information applicable to it until the application receives the data.

1. An application, such as an email program, creates data that will be sent by an end user, such as an email message. The Application layer places a header (encapsulation) field that contains information such as screen size and fonts, and passes the data to the Presentation layer.

2. The Presentation layer places layer 6 header information. For example, the text in the message might be converted to ASCII. The Presentation layer will then pass the new data to the Session layer (layer 5).

3. The Session layer follows the same process by adding layer 5 header information, such as information that the Session layer will manage the data flow, and passes this data to the Transport layer (layer 4).

4. The Transport layer places layer 4 information, such as an acknowledgement that the segment was received in the header, and passes it to the Network layer (layer 3).

5. The Network layer places layer 3 header information, such as the source and destination address so the Network layer can determine the best delivery path for the packets, and passes this data to the Data Link layer (layer 2).

6. The Data Link layer places layer 2 header and trailer information, such as a Frame Check Sequence (FCS) to ensure that the information is not corrupt, and passes this new data to the Physical layer (layer 1) for transmission across the media.

7. The bit stream is then transmitted as ones and zeros on the Physical layer. It is at this point that the Physical layer ensures bit synchronisation. Bit synchronisation will ensure the end user data is assembled in the correct order it was sent.

8. Steps 1 through 7 occur in reverse order on the destination device. Device B collects the raw bits from the physical wire and passes them up the

Data Link layer. The Data Link layer removes the headers and trailers and passes the remaining information to the Network layer and so forth until data is received by the Application layer. Eventually, Device B will receive an email notification displaying a message to indicate that a new email message has been received.

Elena L [17]

Answer:

A is the input array

B = [] ; %B is initially an empty array

for i = 1:length(A)/2 %iterates over A until the midpoint of A

B(i) = A(i) + A(end + 1 - i); %This adds the numbers from the first half and %second half of A, and stores in B

Write a program that convert a temperature in Fahrenheit to the equivalent temperature in Celsius. The initial temperature in Fa

baherus [9]

Answer:

//import the necessary class

import java.util.Scanner;

//Begin class definition

public class ConvertToCelsius{

//Begin main method

public static void main(String []args){

//Create an object of the Scanner class

Scanner input = new Scanner(System.in);

//Display the aim of the program

System.out.println("**Program to convert from Fahrenheit to Celsius**");

//Prompt the user to enter the temperature in Fahrenheit

System.out.println("Please enter temperature in Fahrenheit");

//Receive the user's input

//And store in the appropriate variable

double tempF = input.nextDouble();

//Convert the temperature to Celsius using

//C = (9.0 / 5) * (F - 32)

//C = temperature in Celsius, F = temperature in Fahrenheit

double tempC = (9.0 / 5) * (tempF - 32);

//Display the result

System.out.println("The temperature in degree Celsius is: ");

System.out.println(tempC);

return;

} //End of main method

} //End of class definition

Sample Output

**Program to convert from Fahrenheit to Celsius **

Please enter temperature in Fahrenheit

>> 32

The temperature in degree Celsius is:

0.0

Explanation:

The above code has been written in Java and it contains comments explaining important lines of the code. Please go through the comment. Snapshots of the program and a sample output have been attached to this response.
