Answer and Explanation:

There are three sections to the inquiry.  

1. what occurs inside the PC or host when a bundle is produced by an application.  

2.how it goes from one host that is a source to another host that is a goal with numerous switches sitting in the middle.  

3.what goes inside goal have when it gets a parcel on the system.  

how about we examine individually  

Handling bundle at source machine:  

The application creates a bundle to be sent on the system and sends it to the layer beneath.  

The following layer is known as a vehicle layer which oversees start to finish correspondence between two machines. The convention utilized can be TCP or UDP. What is the contrast between these two conventions is another subject by and large.  

When the parcel is framed at the vehicle layer, it is sent to the system layer which includes source and goal IP in the bundle. A most significant field which is included at IP or system layer is Time To Live (TTL) which is utilized by middle switches/changes to choose if a parcel should be sent or not. (How goal IP is found?)  

After the system layer, the parcel arrives at the information connection or MAC layer, where the source and goal MAC address of machines are included. We will perceive how these fields change between each two neighbors. (How goal MAC is found?)  

The information interface layer pushes this bundle to the physical layer where it is sent as a flood of "0" and "1" on the physical medium accessible.  

Preparing a bundle at switch:  

Steering  

There are three cases which may happen when the switch investigates the directing table for goal IP  

1. On the off chance that there is a section relating to goal IP, we get the interface name the parcel ought to be sent to.  

2. On the off chance that there is no immediate passage, at that point IP is changed over into organize IP utilizing the veil and afterward checked once more. It ought to be noticed that the longest prefix match to locate the best sending interface.  

3. In the case of nothing matches, at that point the switch just advances it to the default goal designed.  

Sending  

Epitome  

Preparing parcel at the goal have  

The parcel is gotten at arrange card, physical layer, which produces a hinder to CPU and CPU peruses bundle in,  

At the information connect layer, goal MAC address is verified whether the parcel is bound to this machine, If indeed, the bundle is sent up to the system layer.  

At the IP layer, parcel approval like checksum confirmation, and so on is done and afterward gave to the applicable vehicle layer.  

Transport later at that point gives it to the fitting port with the goal that it arrives at the right application.

A circuit contains three resistors connected in parallel. The value of R1 is 2 K , the value or R2 is 6 K , and the value of R3
mezya [45]
In a parallel connection, the voltage is same in every branch.
Now, three <span>three resistors connected in parallel.
R1 = 2k ohm
</span>R2 = 6k ohm
R3 = 10k ohm
in parallel, net resisitance  = \frac{ R_{1}R_{2}R_{3} }{R_{1}R_{2} + R_{2}R_{3} + R_{3}R_{1}}

Now, putting the values, we get, R net = 1.30 k ohm.
Ans, voltage = 100 VDC
Thus, power = \frac{ V^{2} }{R} = \frac{ 100^{2} }{1.3 k} \\ \\ where \\ k = 10^{3} 
                      = 7.69 Watt

Write a program that prompts the user to enter a four-digit integer and displays the number in reverse order. Here is a sample r
iVinArrow [24]

Following are the code that is written in c language

#include <stdio.h>

int main() // main function

{

int n1,t; // declaring variable

printf(" Enter an integer :");

scanf("%d",&n1); // taking input

while(n1>0) // iterating over the loop untill the value of n is greater then 0

 {

t=n1%10;

printf("%d",t);

printf("\n");

n1=n1/10;

}

return 0;

}

Explanation:

we taking an integer value n1 and iterating over the loop untill n1>0

suppose n1=1234

then  t=n%10;

means t=1234%10

as % holds reminder means t=4

then print the value of t means print 4

and n1 becomes 123 which is > 0  again condition is checking and same process is follow untill n1>0

output

Enter an integer: 5213
