Client server chat application
A socket represents a connection between two programs on a network and allows them to communicate. The document discusses sockets and how they enable client-server applications like a chat application. It provides code examples of how a chat client would connect to and send messages to a chat server, which would listen for incoming connections and send messages to connected clients. The key aspects are that the server binds to a port and listens for clients to connect, and then messages can be sent bidirectionally between the client and server over their socket connection.

- 2. What is Socket: A socket is one endpoint of a two-way communication link between two programs running on a network. It is one of the most fundamental technologies of computer network programming. Sockets allow network software applications to communicate using standard mechanisms built into network hardware and operating systems. A socket represents a single connection between exactly two pieces of software (a so-called point-to-point connection). More than two pieces of software can communicate with client/server or distributed systems by using multiple sockets.
- 3. . Socket-based softwareusually runs on two separate computers on the network, but sockets can also be used to communicate locally (inter-process) on a single computer like our project. Sockets are bidirectional, meaning that either side of the connection is capable of both sending and receiving data. Sometimes the one application that initiates communication is termed the "client" and the other application the "server“.
- 4. Socket Interface Types: Socket interfaces can be divided into three categories: 1. Stream Socket 2. Datagram Socket 3. Raw Socket [We will talk about Raw Socket only]
- 5. Raw Socket: Incomputer networking, a raw socket is an internet socket that allows direct sending and receiving of Internet Protocol packets without any protocol-specific transport layer formatting. It bypasses the library's built-in support for standard protocols like TCP and UDP. Raw sockets are used for custom low-level protocol development in Client-Server communication. Raw sockets are used in security related applications
- 6. Function of theClient-Server Chat Application: Basic principles: In a connection-oriented client-to-server model, the socket on the server process waits for requests from a client. The client-to-server data exchange takes place when a client connects to the server through a socket. A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent to. An endpoint is a combination of an IP address and a port number.
- 7. . The serverfirst establishes (binds) an address that clients can use to find the server. When the address is established, the server waits for clients to request a service to the server. The server performs the client's request and sends the reply back to the client.
- 8. 8 The java.net packagesupports two common network protocols: TCP: (Transmission Control Protocol) reliable delivery in-order guaranteed connection-oriented bidirectional UDP: (User Datagram Protocol) unreliable delivery no order guarantees no notion of “connection” – app indicates dest. for each packet can send or receive App socket 3 2 1 Dest. App socket 3 2 1 D1 D3 D2
- 9. Methods used inServerSocket Class: The java.net.ServerSocket class is used by server application to obtain a port and listen for client requests.The ServerSocket class has four constructors: public ServerSocket (int port) throws IOException Attempts to create a server socket bound to the specified port. An exception occurs if the port is already bound by another application. public ServerSocket(int backlog) throws IOException Similar to the previous constructor, the backlog parameter specifies how many Incoming clients to store in a wait queue.
- 10. . public ServerSocket(intaddress) throws IOException Similar to the previous constructor, the int address parameter specifies the local IP address to bind to. The int address is used for servers that may have multiple IP addresses, allowing the server to specify which of its IP addresses to accept client requests on. public ServerSocket() throws IOException Creates an unbound server socket. When using this constructor, use the bind() method when you are ready to bind the server socket. If the ServerSocket constructor does not throw an exception, it means that your application has successfully bound to the specified port and is ready for client requests.
