What is the difference between stp cat6 and sftp cat6?

"S" stands for shielding, usually with a wire mesh. When you strip an stp cable you'll see four twisted pairs, surrounded by a "sleeve" of thin wire mesh.

"F" stands also for shielding, but using a metal foil. The foil (a thin metal film) in form of a tape is wrapped around the 4 pairs in a spring fashion (like a leather wrap on a tennis racket handle for example). Usually an ftp cable has an added bare (uninsulated) wire touching the foil, which facilitates easier electrical connection in plugs, outlets etc.

If the cable is marked SFTP, it means that it has both types of shielding, for added protection against interference.

What is the function of sun fire x2400?

Its a Server Developed By Oracle to host any mater of local network HTTP Web Protocol Sites or Web hosting processes. I have one that was used by Myriad Genetics for some of its proprietary information and research, which it held on the local network for access. Though it is not limited to Local networking or Web Site Hosting, it can be used as a remote storage unit or anything you can find to do with it. I intend to use it to learn penetration testing and server hosting.

If the server can run it, then you can do it. So if you have a music library you can host it privately on the web or make a website. You could host a minecraft server, CENT OS 6 has tutorials specifically for that.

However doing anything with a server requires a bit of knowledge about computers, Linux, Unix and the Command line. So if you know don't w about linux I recommend reading about it before hand.

Some one you know has Skype They say they are able to monitor phone calls you make from your home phone land line is this possible?

Although the Skype™ data streams are encrypted with a proprietary algorithm, preventing anyone from listening in on Skype-to-Skype or Skype-to-land line conversations, it is reported that the police in The Netherlands and in Austria have the ability to listen in on Skype calls at will. If they can do it, presumably police and government snoops around the world can do it, too. Whether you talk on a land line, a cell phone or a Skype connection, you should assume that someone can listen in and that someone is listening in.

J. Edgar Hoover, the late former director of the U.S. Federal Bureau of Investigation is credited with saying, "If you don't want it known, don't use the phone."
