I'm learning winsock, creating server and client applications, and I just finished both, client application last, but there's one piece of code that puzzles me.

27015 is a port used in Half-Life based games for dedicated servers.

Ok. What port is used for things like AIM and MSN, so IMing basically. Also, would port 80 work with sending files?

port 80 is normally for http. I'm pretty sure you could use just about any port you want for anything, though. Just matters if it's already in use.

You can use any port that is between 0 to 65535. So you can do file transfer as well on any you like Smile

. If its used or not, doesn't matter.

I thought certain ports were used for certain things though?

I think I understand this now. I can use about any port I want from 0-65536. But the router filters traffic through ports, so like web traffic is filtered into port 80, so for example if you set your router to not allow traffic coming through port 80, you wouldn't be able to browse the internet or have traffic coming from a program, i.e. AIM (though I doubt it uses port 80).
