If one examines the dimensions of a CD-ROM jewel box, one
|
|
can determine the approximate volume as being about seven
|
|
cubic inches (1/4 5.5 x 5.5).
|
|
|
|
A CD-ROM holds about 700 megabytes of data...or about
|
|
100 megabytes per cubic inch.
|
|
|
|
There are 1728 cubic inches per cubic foot.
|
|
|
|
If you take a minivan with a 22 cubic foot cargo space and
|
|
load it with CD-ROMs, you have a 38,016 x 10 to the 8th byte
|
|
capacity.
|
|
|
|
Since each byte contains eight bits, you have a 30,412,800
|
|
megaBIT capacity.
|
|
|
|
IF (and you can't) you could use all 1.5 megabit capacity of
|
|
a T1 line to transmit data, it would take 20,275,200 seconds
|
|
to transmit that data.
|
|
|
|
Since there are 3600 seconds in an hour, that's 5,632 hours.
|
|
|
|
With 24 hours in a day, it would take 234.7 days to transmit
|
|
that data from Las Vegas to San Diego.
|
|
|
|
The minivan can get that data there in five hours.
|
|
|
|
Even from Las Vegas to New York City, it would only take
|
|
three or four days with layovers for steaks and brewskies.
|
|
|
|
The lesson is: never underestimate the bandwidth of a
|
|
minivan loaded with CD-ROMs, diskettes, or tape.
