Does Mobile phone have Server : Port Scheme ?

Question

Hi

I hope I can get all the help i can get here. I am new to mobile phone programming. I find networking very interesting and I have this question:

1. Does Mobile phone like WinMo or other phone have Server:Port scheme and what are the ports ?

To show what I mean, I use PC to demonstarte, there are many ports ( restricted and established ). The below is the Server : Port scheme

Server : port example WebServer 80

So, to use a TCPListener on PC , I can use any port as long as there are not restricted and establsihed) to listen incoming TcpClient .

2) How do I use a TCPListener and Which portNo I need to use to listen incoming TcpClient from the other end in Net Compact Framework?

Thanks
