Sometimes, like in a school computer lab or in an office, you need to hook up several computers to one printer, or several computers need to connect to one file server, or maybe you have several devices (such as a scanner and a CD-ROM player) that you need to hook into one computer. Well, the only way to connect all these devices together, since there is only one port, or connecting place, on the back of the computer, is to connect each object (each device) to the next one in line, making a daisy chain.
For instance, to connect the scanner and the CD-ROM player to your computer, you would have a cable going from the computer to the CD player, and another cable from the CD player to the scanner. Through this “chain,” the computer can use the scanner, even though it is not directly connected to it.
