Take an online course,or maybe do special trainings,practice and study.
Answer:
d. all of the statements are correct
Explanation:
Frame Relay is a high-performance WAN protocol that operates at the physical and data link layers of the OSI reference model. i.e Layers 1 and 2 They are designed to cope with bursty traffic. Frame relay is also a form of data networking based on packet switching in which the packets are variable in length and experience packet delays.
Based on the above definition the correct statement is option d as all of the statements define in the other option correctly defines the function of frame relay.
Answer:
The program to this question can be describes as follows:
Program:
#include <stdio.h> //defining header file
int main() //defining main method
{
int n,i,x=0; //defining integer variable
printf("Enter a number: "); //print message
scanf("%d",&n); //input value from the user
printf("%d\n",n); //print input value
for(i=1;i<n;i++) //loop to count reverse number
{
x=n-i; //calculate value
printf("%d\n",x); //print value
}
return 0;
}
Output:
Enter a number: 3
3
2
1
Explanation:
- In the above program, three integer variable "n,i and x" is declared, in which variable n we take input from the user end and the variable i and x is used in the loop to calculate the value in the reverse order.
- In the next step, a loop is declared, in which the variable x calculates the value in reverse order and uses a print method to print its value.
One way could be to check the code of the program.
But of course this might not be possible... Not everyone knows a programming language. And even if you did, you might not know the programming language they used.
Another way is to download a program that monitors your incoming connections and outgoing connections from your computer/android/iphone.
When someone or something connects to your device, the program should alert you. Or when the computer makes a connection to a website/device.
