IP multicast is a method of sending IP packets from a single sender to multiple receivers simultaneously. It is a technique for efficient one-to-many and many-to-many communication over the internet. In IP multicast, a single sender sends a single copy of a packet to a multicast group address, which is a special class D IP

DatagramChannel is a class in Java’s NIO (New I/O) package that represents a channel for sending and receiving datagrams through a UDP (User Datagram Protocol) network socket. It provides a non-blocking, event-driven way of sending and receiving UDP packets. Here’s an example of how to use DatagramChannel to send and receive UDP packets in Java:

In Java, the User Datagram Protocol (UDP) is implemented using the DatagramSocket and DatagramPacket classes, which are part of the java.net package. To use UDP in Java, you can create a DatagramSocket object, which represents a socket for sending and receiving datagrams. You can then use the DatagramPacket class to create datagrams and send them

The User Datagram Protocol (UDP) is a transport layer protocol that is used to send and receive datagrams, which are packets of information that contain a payload and destination information. Unlike the Transmission Control Protocol (TCP), which is a connection-oriented protocol that provides reliable communication, UDP is connectionless and does not provide guaranteed delivery of

The SelectionKey class in Java is a part of the Java NIO (New I/O) package. It represents the registration of a channel with a Selector object and contains information about the registered channel, such as its readiness to perform I/O operations, and the operations that the channel is interested in, such as reading or writing

The Selector class in Java is part of the NIO (New Input/Output) API and provides a way to perform readiness selection on one or more channels. Readiness selection allows an application to monitor multiple channels for readiness and perform I/O operations only when the channels are ready. This can be more efficient than blocking on

Readiness selection is a key feature of Java’s NIO (New Input/Output) API that allows developers to efficiently manage I/O operations on multiple channels. In traditional blocking I/O operations, the program execution is blocked until the I/O operation completes, which can lead to inefficient use of system resources and decreased performance. Readiness selection allows an application

Asynchronous channels in Java 7 provide a way for developers to perform non-blocking I/O operations on channels, allowing for more efficient handling of I/O operations in high-performance applications. In C, asynchronous I/O operations are typically implemented using operating system-specific APIs such as epoll on Linux or kqueue on BSD and macOS. These APIs allow applications

The Channels class in Java is a utility class that provides various methods for working with channels, which are a key concept in Java’s NIO (New Input/Output) API. Channels are objects that represent a connection to a data source or a data destination, such as a file, a network socket, or a pipe. They provide

In Java network programming, ServerSocketChannel is a class that provides a way to listen for incoming TCP connections from clients. It is a type of SelectableChannel that can be used for non-blocking I/O operations, which allows the application to perform other tasks while waiting for incoming connections. To create a ServerSocketChannel, you can call the
