How are udp and tcp ports assigned?

irishdude11 · 2011-07-24 12:38:19

If I write a simple server application I have to specify it's port. However I don't have to specify ports for the client. So how does the port get assigned and are they assigned differently for tcp and udp?

I don't understand the question! If you don't specify a connection port in the client it can't possibly connect to the server? The port you create at the server end is its listening port, this is the port the client would connect to (but its source port would be different).
