Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) is a network protocol for carrier transmission that operates in the Medium Access Control (MAC) layer. In contrast to CSMA/CD (Carrier Sense Multiple Access/Collision Detection) that deals with collisions after their occurrence, CSMA/CA prevents collisions prior to their occurrence.AlgorithmThe algorithm of CSMA/CA ... Read More

Carrier Sense Multiple Access with Collision Detection (CSMA/CD) is a network protocol for carrier transmission that operates in the Medium Access Control (MAC) layer. It senses or listens whether the shared channel for transmission is busy or not, and defers transmissions until the channel is free. The collision detection technology ... Read More

P-persistent CSMA is an approach of Carrier Sense Multiple Access (CMSA) protocol that combines the advantages of 1-persistent CMSA and non-persistent CMSA. Using CMSA protocols, more than one users or nodes send and receive data through a shared medium that may be a single cable or optical fiber connecting multiple ... Read More

1-persistent CSMA is an aggressive version of Carrier Sense Multiple Access (CMSA) protocol that operates in the Medium Access Control (MAC) layer. Using CMSA protocols, more than one users or nodes send and receive data through a shared medium that may be a single cable or optical fiber connecting multiple ... Read More

At first set the date with java.util.Date −java.util.Date date = new Date();Now, convert the date to LocalDate −Instant instant = Instant.ofEpochMilli(date.getTime()); System.out.println("LocalDate = "+LocalDateTime.ofInstant(instant, ZoneId.systemDefault()).toLocalDate());Example Live Demoimport java.time.Instant; import java.time.LocalDateTime; import java.time.ZoneId; import java.util.Date; public class Demo {    public static void main(String[] args) {       java.util.Date date = ...

First, declare an integer array and add some elements −Integer arr[] = { 40, 20, 30, 10, 90, 60, 700 };Now, convert the above array to List −List list = Arrays.asList(arr);Now, use Comparator and the reverseOrder() method. Using max() will eventually give you the maximum value, but with reverseOrder() it ... Read More

Let’s say the following is our array −Integer[] arr = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20};Now, we can convert it to a list before shuffling it −List<Integer>list = Arrays.asList(arr); Collections.shuffle(list);The above shuffling generates random elements. Display them like this −for (Integer res: list) {    System.out.print(res ... Read More

Non-persistent CSMA is a non – aggressive version of Carrier Sense Multiple Access (CMSA) protocol that operates in the Medium Access Control (MAC) layer. Using CMSA protocols, more than one users or nodes send and receive data through a shared medium that may be a single cable or optical fiber ... Read More
