Internet socket programming in c++ explanation needed
<p>I have two computers, and I have created a network between them, One is server (Windows Server OS) and the client (Windows 10). Both computer also has connection to internet through wifi. To connect two Systems I am using Ethernet Cable</p>

<p>I like to know if I create a program for client in c++ that send packets using internet socket. Should I also create a listener on server too. And should I use port 80 to send packets and same port on server to listen to arriving packets?</p>
