Why USB is a Great Standard for Cables
Why USB is a great standard.
Lets recap on the different types of usb
connectors. First off, there is USB "A"
This connector is generally used for pc connection. It's the
largest and therefore not a good candidate for many USB
peripherals. Digital cameras for instance, are getting small and
smaller and in turn will require small ports for connection. The
most common connection currently used on digital cameras is USB Mini "b".
It doesn't actually look much like USB A or USB B connectors,
but it is definitely smaller. (Thus, the "mini" name). USB
Mini-B connectors come in both a 4 pin and 5 pin configuration.
It's important to know which one your device needs before buying
as they are almost never compatible with one another.
USB B
Connectors are small than "A" and if you get really
creative, are shaped like a 'B". Although not really. The "B"
Connector in some form or another (Standard B, Mini-B) is used
the majority of the time as the device connection. On Digital
cameras, mp3 players, etc, you find the Mini-B's. On Printers
you find regular "USB B" connections.
So now that we understand a little bit about the different types
of connectors, lets discuss why USB is a great standard for
computer manufacturers and device manufacturers to agree on.
Perhaps the first thought that comes to mind is simplicity.
There are literally thousands of different cable varieties
available. Different variations in connectors, cable type,
number of conductors and pinout are used for thousands of
different computers and devices. Pin outs alone can be deceiving
as two cables that look 100% the same can actually be designed
for 2 completely different devices. Narrowing our choices down
to "USB B" and "USB A" will help substantially when the average
consumer needs a new cable. Many people own special devices for
their computers, but not many people can name even 10 different
types of cables.
The second, and probably the most significant reason that the
USB Standard is so great is economical. A basic USB cable
can be had for $5-6. However, a more specialized cable (such as
those for iPods) may run you $20, $30, or more depending on
where you go. Had Apple decided to use the standard USB cable
it's patrons would be able to buy the needed connectivity at a
fraction of the cost. However, the Apple maybe would have lost
out on the extra profit.
