Some of them are default ports in an application; for example, when you surf the internet, you use port 80; when you SSH to a remote server (or your Pi), you use port 22. Thus, for a simple server implementation, we will use an IP address and a port. This combination defines a server uniquely all over the world. In the following example, we will use our localhost machine for the demo. So, instead of an IP ...
