Hi, dko-ga: The Internet is much more than just the "World Wide Web". It's a patchwork of networks which share information through standarized protocols (like TCP/IP) that allow various kinds of peer-to-peer communication. A good overview is here: [How Internet Infrastructure Works by Jeff Tyson] http://computer.howstuffworks.com/internet-infrastructure.htm A local power outtage that takes down your computer is unlikely to have any effect on a Web server that hosts content which you were browsing remotely (HTTP). However other kinds of Internet interactions such as file transfers (FTP) may have adverse consequences due to a power outtage at one end of the communication. The standards for such protocols attempt to limit consequences of service interruptions. A file transfer, for example, is probably broken into small pieces (which may wind up being routed over the Internet in a variety of ways), but sufficient information is provided in the "packets" for them to be reassembled at the destination into a copy of the original file or else detect that the transfer has failed. regards, mathtalk-ga
