Cookie Preferences The processes that use a socket can reside on the same system or different Thank you for your valuable feedback! The main difference between working with TCP and UDP in Python is that, when creating the socket, you have to use SOCK_DGRAM for UDP and SOCK_STREAM for TCP. It needs a new socket so that it can continue to listen to the original socket for connection requests while tending to the needs of the connected client. The syntax is. However, you may have a higher-level Socket class which encapsulates the behaviour of the low-level socket. In practice, due to the proliferation of the TCP/IP protocols in use on the Internet, the term network socket usually refers to use with the Internet Protocol (IP). In JavaScript development, having the right tools at your disposal can significantly improve your productivity and code quality.

It is important to close the connection by closing the socket as well as input/output streams once everything is done. Allows you to log values and display them in the editor, providing additional visibility into code execution flow. When the server accepts the connection, it gets a new socket bound to the same local port and also has its remote endpoint set to the address and port of the client. In the above example, a socket is created and made ready to listen for connection signals from the client.
