Guess what! There is a third type of port, and it is a physical connection point to your box, as in a serial port, printer port, keyboard port, etc. TCP/UDP ports are virtual access points, which all connect through the physical ethernet port to your machine. These two ports (TCP and physical) have a common backing concept... connection points between equipment. However, you must remember that physical ports consist of pins, sockets, and plugs... TCP ports are virtual. As for software ports, I'm not really sure where the term came from... However, these ports have nothing to do with physical ports or network ports... if the name isn't a coincidence, at least there is no modern connection between the two. As I finish this, I think that you might be confused if your English isn't great. Right now, I'm too tired to clarify this. Therefore, if you need extra help deciphering this, just reply with "What the fuck?" and I'll get to it when I'm less sleepy. :) -- Andrew Hesford ajh3@chmod.ath.cx To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
