How to display TCP/UDP connections?

In my last video, I talked about TCP/UDP network sessions, connections, sockets, and ephemeral port numbers. Today my topic is about getting detailed connection information when a computer is communicating with other computers. Specifically, I will demonstrate how to display TCP/UDP connection information with netstat. I will also briefly introduce TCPVviwer, Process Explorer, and Netacview.
