Answer:
There could be a collision if a hidden node problem occurs.
Explanation:
CSMA/CA(carrier sense multiple access/ collision avoidance) is a multiple access method in wireless networking, that allows multiple node to transmit. Collision avoidance of this method is based on preventing signal loss or downtime as a result of collision of transmitting multi signals.
If a node at step 4(transmit frame) sends the first frame, the node still needs to send a RTS(request to send) and to receive a Clear to send (CTS) from the WAP, the is to mitigate the issue of hidden node problem as all frame are treated as unit, so other listening nodes, not detected would seek to connect and transmit as well.
Answer:
The following are the code to this question:
code:
System.out.println(x); //use print method to print value.
Explanation:
In the given question, it simplifies or deletes code in the 11th line. This line has a large major statement.
In the case, the tests fail because only 1 line of output is required by the tester, but two lines are obtained instead.
It's to demonstrate that the input/output or testing requirements function throughout the model.
Answer:
import java.util.Scanner;
public class Speed{
int speed;
public Speed(int speed){
this.speed = speed;
}
public void checkSpeed(){
if(speed >= 24 || speed <= 56){
System.out.println("Speed is normal");
}
else
System.out.println("Speed is abnormal");
}
public static void main(String...args){
Scanner input = new Scanner(System.in);
int userSpeed = 0;
System.out.println("Enter a speed: ");
userSpeed = input.nextInt();
Speed obj1 = new Speed(userSpeed)
obj1.checkSpeed();
}
Explanation:
The
piston engine uses the crankshaft to convert the reciprocating motion of the
piston into rotary motion.
<span>The
crankshaft is used to convert reciprocating motion of the piston into rotary
motion, while the conversion process is called torque, which is a twisting
force. Aside from crankshaft, there are a total of four parts of the engine
that work together in order to convert the reciprocating motion into rotary
motion namely cylinder, or also called the chamber of the piston, the piston itself,
and the connecting rod.</span>
Answer:
The method definition to this question can be given as:
Method definition:
public void clear(int[] arr, int num) //define method clear.
{
if (num == 0) //if block
{
return 0; return value.
}
else //else block
{
arr[num - 1] = 0; //assign value in arr.
return arr[]; //return value.
}
}
clear(arr, num - 1); //calling
Explanation:
The description of the above method definition as follows:
- Firstly we define a method that is "clear" that does not return any value because its return type is "void". This method accepts two integer variables that are "arr[] and num" where arr[] is an array variable and num is an integer variable.
- Inside a method, we use a conditional statement in if block we check that num variable value is equal to 0. if this condition is true so, it will return 0 otherwise it will go to else block in else block it will assign value in variable arr[num-1] that is "0" and return arr value.
