Dear Amy: How long have fax machines been around? --Julia, San Francisco

Dear Julia: In 1843, a Scottish man named Alexander Bain patented the first machine to copy an image from one piece of electrically conductive paper to another. In1895, Ernest A. Hummel of the U.S.A. invented the Telediagraph to send pictures via telegraph lines. The ideas behind Bain's and Hummel's inventions are still important to today's developers of fax machines.

Dear Amy: Is there really a bus in my computer? --William, Penang, Malaysia

Dear William: There is a bus in your computer, but it isn't big and yellow. A bus is a path on the motherboard that connects the CPU to the CD-ROM drive, hard drive and other attachments. The picture at http://www.howstuffworks.com/microprocessor2.htm will help you better understand this. When a signal is sent, it goes to each device connected to the mainboard. Only the devices that the signal was directed toward pay attention to it; the others ignore it.
