One of the most common ways to transport data from one computer to another
is to write them onto magnetic tape or removable media (e.g., recordable DVDs),
physically transport the tape or disks to the destination machine, and read them
back in again. Although this method is not as sophisticated as using a geosynchronous
communication satellite, it is often more cost effective, especially for
applications in which high bandwidth or cost per bit transported is the key factor.
