10. In step 4 of the CSMA/CA protocol, a station that successfully transmits a frame begins the CSMA/CA protocol for a second fr

Neporo4naja [7]

Answer:

It is done to avoid collision among the channel.

Explanation:

CSMA/CD stands for carrier sense multiple access/collision detection.

It is a media access protocol that tells the devices how to respond when a channel is used simultaneously by two devices. The main purpose is to manage the transmission when a collision is encountered.

In the given scenario when the channel is detected idle, the station does not transmits second frame in order to avoid collision. CSMA/CD protocol is designed so that after transmission of first frame, second frame transmission is started at step 2 instead of step 1.

Following is given the flow chart that depicts the working of the protocol CSMA/CD:

Mekhanik [1.2K]

Answer:

#include<iostream>

using namespace std;

//main function

int main(){

//nested for loop

for(int i=9;i>=1;i--){

for(int j=1;j<=i;j++){

cout<<j<<" "; //display

}

return 0;

}

Explanation:

Include the library iostream for using the input/output instruction in the c++ programming.

Create the main function and takes nested for loop. Nested for loop means, for loop inside the another for loop.

For every value of outside for loop, inside for loop execute.

we make outer for loop in decreasing format, means it start from 9 and goes to 1 and inside for loop make in increasing format, means loop start from 1 and it goes to that value which is provided by the outer loop.

and print the output for every cycle.

Lets dry run the code:

the outer loop starts from 9 and it checks the condition 9>=1, condition true. then the program moves to the inner loop which starts from 1 and goes to the 9.

first, it also checks the condition 1 <= 9, condition true and prints the number from 1 to 9.

then, i is reduced by 1. it means i become 8.

then, the above process continues from 1 to 8 and so on...

the loop process will terminate if the outer loop terminate.

Finally, we get the output.
