...CONNECTION OF CLIENT AND SERVER RUNNING ON DIFFERENT COMPUTERS

....Hello guys,,,,i know how to connect a client program and a server program
running on the same computer. Can some one help me on how to connect the
client program and the server program which run on two different computers
over the internet???

The client needs the IP address of the server.
Do you use localhost or 127.0.0.1? Replace that with the server's IP address
