Vb6 Tcp/ip

[sephirothzero85]

Alright, I understand a little more already. Winsocks help you to connect to each other computer and transfer data among it. The server will open port to all other clients. Clients just identifies the server's port and server will listen to the client if the port is right? Correct? Well then, when server listens to the port, not only then, client have to identifies the server's ip address too right? So... the only thing i dont understand is, will the other client will make the server crash due to maybe perhaps, same ip address? For example, Client A(192.168.1.2) and Client B(192.168.1.2) connects to Server(192.168.1.1). If this is possible, then server will be sending the same data to client who has 192.168.1.2 IP right? or receiving individual? Or maybe Server identifies the machine name hence IP could be anything right? Hence, i would like to know, how does those msn,mirc,icq,yahoo and etc. works? I can see the logic is simple, but still i want to know how to operates. Oh, 1 more thing, port... so with the port like 4000 for example, is used on software A and software B. Will they be transfer same data? or individual? If individual, how they work? Or port is just like a gate pass for you to go through? Hope you guys dont mind my dummy. Thanks all.
