one, ports are sealed the way to communicate with other computer systems?
performed by default, you can see that did not add a port, that port is shut easy methods to talk with other computer systems it?

Microsoft Office 2010 Professional Plus, with all the Telnet protocol Other gear can also be landing about the machine to open a random port higher than 1024 together with the server 23 to services port. computer solutions, you may say that these ports are standing. The random open ports is temporary, which include the internet whenever you go to a web page, your computer randomly open a port 1026 to connect to the web server port eighty, finished off once the entry page, follow the machine's 1026 port closed, server, port 80 is continually open.
