What is server socket and client socket?

In the TCP/IP context, these terms are defined as follows: Server. A process that waits passively for requests from clients, processes the work specified, and returns the result to the client that originated the request. Client. While clients communicate with one server at a time, servers can serve multiple clients.

What is the difference between socket and server socket?

java.net.Socket A socket is an endpoint for communication between two machines. ServerSocket is again a Socket with additional features of server endpoint. The server features includes listening to the port and accepting an incoming connection etc…

What are socket servers?

A socket server is usually a multi-threaded server that can accept socket connection requests. A socket client is a program/process that initiates a socket communication request. In Unix the BSD variant provided a programmatic way for one process to communicate across the network to another process, a socket API.

What is the difference between a client socket and a server port?

a server listens on a host and a port, receives requests (e.g. through a socket connection), and then sends a response to the client who initiated the socket connection. The client is what sends a request to that server socket, and waits for a response.

Why does a server program need two sockets?

2 Answers. The reason is that TCP has two different kinds of state that you want to control, whereas UDP has only one.

What is socket and server socket in Java?

Java Socket programming is used for communication between the applications running on different JRE. Socket and ServerSocket classes are used for connection-oriented socket programming and DatagramSocket and DatagramPacket classes are used for connection-less socket programming.

What do you mean by socket programming explain with example?

Definition: A socket is one endpoint of a two-way communication link between two programs running on the network. 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.

Is socket and Port the same?

Both Socket and Port are the terms used in Transport Layer. A port is a logical construct assigned to network processes so that they can be identified within the system. A socket is a combination of port and IP address. The same port number can be used in different computer running on same software.

How do server sockets work?

The server socket listens for incoming connections. A server creates a socket, binds the socket to an IP address and port number (for TCP and UDP), and then listens for incoming connections. When a client connects to the server, a new socket is created for communication with the client (TCP only).

What is socket programming and how does it work?

Socket programming is a way of connecting two nodes on a network to communicate with each other. Basically, it is a one-way Client and Server setup where a Client connects, sends messages to the server and the server shows them using socket connection.

What is a server and a socket?

Normally, a server runs on a specific computer and has a socket that is bound to a specific port number. The server just waits, listening to the socket for a client to make a connection request.

How do sockets work on the client side?

On the client side, if the connection is accepted, a socket is successfully created and the client can use the socket to communicate with the server. The client and server can now communicate by writing to or reading from their sockets.

How to create a socket application in Java?

To create the client application, we need to create the instance of Socket class. Here, we need to pass the IP address or hostname of the Server and a port number. Here, we are using “localhost” because our server is running on same system. Let’s see a simple of Java socket programming where client sends a text and server receives and prints it.
