In this article, Rahul shows us how to create a client-server socket program in Perl and then demonstrates it by pinging the server.
What is a socket? Just another bit of computer jargon? Devling a little into networking history, it is a Berkeley UNIX mechanism of creating a virtual duplex connection between processes. This was later ported on to every known OS enabling communication between systems across geographical location running on different OS software. If not for the socket, most of the network communication between systems would never ever have happened.
