What is socket and how it works?
Sockets are commonly used for client and server interaction. A socket has a typical flow of events. In a connection-oriented client-to-server model, the socket on the server process waits for requests from a client. To do this, the server first establishes (binds) an address that clients can use to find the server.
What can I do with socket programming?
Sockets allow you to exchange information between processes on the same machine or across a network, distribute work to the most efficient machine, and they easily allow access to centralized data. Socket application program interfaces (APIs) are the network standard for TCP/IP.
What is a Java socket?
A socket is one endpoint of a two-way communication link between two programs running on the network. The java.net package in the Java platform provides a class, Socket , that implements one side of a two-way connection between your Java program and another program on the network.
What do you need to know about a socket?
The socket needs to have an address. It’s of type IpEndPoint. Each socket is identified through the IP address, which is useful to locate the host’s machine, and the port number to identify which program is using the socket inside the machine.
What kind of protocols can you use with sockets?
While the former is used for high level operations using sockets, the latter is used for any low level operations when working with sockets. When working with sockets you can use either the TCP/IP (Transmission Control Protocol/Internet protocol) or UDP/IP (User Datagram Protocol/Internet protocol) communication mechanisms.
Why are sockets a must for a developer?
Thanks to its powerful features, sockets are becoming a must to learn technology for developers. As sockets are based on client/server architecture, this application is composed of a server and a client. The server will reserve a port number. Then it will listen to any upcoming client. The client then will attempt to connect to the server.
How to use sockets in a.NET application?
To use sockets in .NET applications, we have to add the following using statements: Now we can create a socket object: Let’s create a click event that will enable the created socket to set its IpEndPoint and the protocol type. But before that, a socket needs permission to work, because it will use a closed port number.
