Answer:
To avoid collision of transmitting frames.
Explanation:
CSMA/CA, carrier sense multiple access is a media access control protocol of wireless networks that allows for exclusive transmission of frames and avoidance of collision in the network. When a frame is not being sent, nodes listening for an idle channel gets their chance. It sends a request to send (RTS) message to the access point. If the request is granted, the access point sends a clear to send (CTS) message to the node, then the node can transmit its frame.
Many nodes on a wireless network are listening to transmit frames, when a frame is transmitting, the node has to wait for the access point to finish transmitting, so it sends a RTS message again to exclusively transmit a second frame.
Answer:
I did this in C# & Java
Explanation:
C#:
public static void Main(string[] args)
{
int input = Convert.ToInt32(Console.ReadLine());
Multiply(input);
}
public static int Multiply(int input)
{
int ans = 0;
for(int i =1; i<=10; i++)
{
ans = i*input;
Console.WriteLine(i + "*" + input + "=" + ans);
}
return ans;
}
Java:
public static void main(String[] args)
{
Scanner myObj = new Scanner(System.in);
int input = Integer.parseInt(myObj.nextLine());
Multiply(input);
}
public static int Multiply(int input)
{
int ans = 0;
for(int i =1; i<=10; i++)
{
ans = i*input;
System.out.println(i + "*" + input + "=" + ans);
}
return ans;
}
